1 INTRODUCTION
Explain that
bull This short training programme is about oily water
bull It is in two parts This part is about where oily water comes from how to minimise its quantity and how to control its content so that the separator and oil content monitor are able to work properly Part 2 covers how the separator and oil content monitor work how to operate and maintain them simple security precautions and an outline of the new generation of separators
bull You will show them a video lasting about 15 minutes
bull You will then lead a discussion about the points raised in the video The main objective of this discussion is to identify and agree ways of handling oily water better on your ship Stress that you want their ideas and suggestions
Remind the group that the discharge of oily water whether through the separator or to shore based facilities is strictly controlled by internationally agreed regulations and it is inspected by port state authorities The limit for discharge at sea is 15ppm parts per million] and the ship must be en route during discharge
Ask them if they know what 15ppm means It is roughly a coffee cup of oil in 20m3 of water

3 POINTS FROM THE VIDEO
Ask the group what they thought were the important points from the video In summary these are
bull There are many sources of oily water - such as leaks spills overflows and condensation
bull Good housekeeping can reduce the quantity of oily water coming from many of these sources A leak that drips every second can put 30 or 40 litres into the bilges in a day
bull Cleaning is a particular issue
bull Controlling the content as well as the quantity of the oily water that reaches the bilges is important If it contains too much oil the separator may struggle to cope with it If it contains impurities such as soot the OCM may not work properly
4 SOURCES - LEAKS ETC
bull Ask the group for suggestions about how to reduce the amount of oily water from leaks spills and overflows
bull Check that they understand and are following the procedures for handling items contaminated with oil - filters oily rags and so on Ask for any ideas about how to do this better
bull Stress the importance of keeping as much oil as possible out of the bilges by for example carefully emptying drip trays
bull Add any points for improvement which the group have not suggested
9
ENGINE ROOM WASTE MANAGEMENT OILY WATER AND SEPARATORS
5 SOURCES - CLEANING
Discuss and identify improvements in the procedures for the following cleaning tasks
bull Keeping bilges and holding tanks as clean as possible
bull Preventing emulsifiers getting into the bilge water
bull Cleaning the air cooler in the charge air receiver
bull Disposing of gas oi l used for clea ning
bull Handling water contaminated with soot from pressure washing the waste heat recovery unit in the funnel wh ile in port

3 HOW THE SEPARATOR AND OIL CONTENT MONITOR WORK
Check that those taking part understand the principles of how the separator and OCM wo rk Answer any questions they may have Points to stress are
bull Separation starts in the holding tank Because oil and water have a different specific gravity the static mixture of the two liqu ids in the tank will separate with oil ris ing to the top wh ich from there can be drawn off into a waste oil tank This lowers the concentration of oil in the water towards the bottom of the tank making it eas ier for the separator to deal with
bull The present generation of separators contain two stages

4 OPERATION OF THE SEPARATOR
The details to cover in th is secti on will obvi ously depend on the make and mode l of the separator on your sh ip Find out wh ether t he group ever experience any problems when running the equ ipment Ask for any suggestions th ey may have for im provements
You may wish to stress the following general points which were covered in the video
bull It is good practice to put the manufacturers operating instructions in an easily visible position near the separator Encourage those who operate the equipment to check the instructions even if they have used it before Sometimes even experienced operators can overlook something important
bull At the end of each cycle whoever is operating the separator should back-flush the equ ipment with clean water This cleans the filters in Stage 2 and removes any remaining oil from Stage 1 The separator should be left full at clean water so that it is ready for the next time it is used
bull At the beginning of each separat ion cycle it is important to zero test the OCM with clean water
bull At the beginning and end of each cycle it is essential to check the ship s exact posit ion as th is information must be entered in the Oil Record Book
bull On many ships [yours] there is a float in the bilge holding tank wh ich will stop the separator running before the concentration of oil in the water becomes too great for it to cope with If this is not the case on your sh ip stress that the operator should estimate the amount of pumpable water in the system so that it can be shut down before the separator is flooded with concentrated oi l It is not acceptable pract ice to run the equipment until the alarm sounds
Explain and discuss any standing orders on your ship which are additional to the procedures called for in the statutory regulations
15
ENGINE ROOM WASTE MANAGEMENT OILY WATER AND SEPARATORS
5 MAINTENANCE
Discuss the PMS for your separator with the group
bull Check that they understand the important points which it covers
bull Find out whether they have any problems maintaining the equipment or ideas for improvement
bull Expla in how you verify that maintenance schedules are being followed
bull Stress the importance of keeping sufficient spares on board
VIDEOTEL PRODUCTIONS
Explain the key points from the fault list for your separator Stress that when faults occur
bull They must stop the separator runn ing as soon as the fault develops rather than waiting until they have identified the problem There must never be any r isk that water with an oil content above the 15 ppm Limit could be discharged overboard
bull They must avoid any temptation to break or bend the rules If a problem arises which can only be solved by doing something illegal that is an issue for the shore office to sort out
6 SECURITY
The video highlighted the use of
bull White boxes These prevent anyone tampering with the OCM
bull Seals on valves and flanges in the engine room These ensure that no one can interfere with any pipe work containing oil or oily wastes Some seals are plastic so that they can be removed quickly in an emergency Others are chains secured by padlocks The numbers of plastic seals are recorded in the engine room logbooks and the Chief Engineer keeps the keys to any padlocks
Discuss with the group the steps taken on your ship to protect the security of the equipment for handling oily water

ENGINE ROOM WASTE MANAGEMENT OILY WATER AND SEPARATORS VIDEOTEL PRODUCTIONS
7 THE NEW GENERATION OF SEPARATORS
As the student pointed out to the engineer in the video the current generation of separators have some important disadvantages and limitations They cope badly with dirt soot emulsifiers and oil at too high a concentration Rough sea conditions lower the efficiency of separation For these reasons it is often
difficult for even the most experienced engineers to make them work properly
That is why the IMO has introduced a revised set of gu idelines and specifications for separators These
are set out in M EPC107[491
MEPC stands for Marine Environment Protection Committee This is a committee of the International Maritime Organization - the IMO The numbers simply tell us that this is the Committee s 107th
resolution passed at their 49th session The full title of the resolution is
Revised guidelines and specifications for pollution prevention equipment for machinery spaces of ships
In addition to the usual introduction explanation of the background and definitions the resolution
contains
bull Tech nical specifications
bull Specifications for type approva l testing of pollution prevention equipment
bull Installation requirements
17
ENGINE ROOM WASTE MANAGEMENT OILY WATER ANO SEPARATORS VIOEOTEL PRODUCTIONS
These new requirements apply to
bull Installations fitted to ships the keel of which are Laid or which are at a similar stage of construction on or after 1 January 2005 and
bull To new installations fitted on or after 1 January 2005 to ships the keel of which were laid or which were at a similar stage of construction before 1 January 2005 in as far as is reasonable and practicable
The requirements for design manufacture testing type approval and so on are very detailed but tell the group that the good news for ships engineers is contained in the following single paragraph
It should be understood that a 15ppm Bilge Separator must be capable of handling any oily mixtures from the machinery space bilges and be expected to be effective over the complete range of oils which might be carried on board ship and deal with oil of very high relative density or with a mixture presented to it as an emulsion Cleansing agents emulsifiers solvents or surfactants used for cleaning purposes may cause the bilge water to emulsify Proper measures should be taken to minimise the presence of these substances in the bilges of a ship With the possibility of emulsified bilge water always present the 15ppm Bilge Separator must be capable of separating the oil from the emulsion to produce an effluent with an oil content not exceeding 15ppm
Explain that a number of manufacturers have already risen to this challenge using a variety of technical approaches including centrifuges sophisticated membranes biological systems and evaporation If your company is introducing new generation separators explain the approach on which they will be based

bull It is in two parts This part is about where oily water comes from how to minimise its quantity and how to control its content so that the separator and oil content monitor are able to work properly Part 2 covers how the separator and oil content monitor work how to operate and maintain them simple security precautions and an outline of the new generation of separators
bull You will show them a video lasting about 15 minutes
bull You will then lead a discussion about the points raised in the video The main objective of this discussion is to identify and agree ways of handling oily water better on your ship Stress that you want their ideas and suggestions
Remind the group that the discharge of oily water whether through the separator or to shore based facilities is strictly controlled by internationally agreed regulations and it is inspected by port state authorities The limit for discharge at sea is 15ppm parts per million] and the ship must be en route during discharge
Ask them if they know what 15ppm means It is roughly a coffee cup of oil in 20m3 of water

3 POINTS FROM THE VIDEO
Ask the group what they thought were the important points from the video In summary these are
bull There are many sources of oily water - such as leaks spills overflows and condensation
bull Good housekeeping can reduce the quantity of oily water coming from many of these sources A leak that drips every second can put 30 or 40 litres into the bilges in a day
bull Cleaning is a particular issue
bull Controlling the content as well as the quantity of the oily water that reaches the bilges is important If it contains too much oil the separator may struggle to cope with it If it contains impurities such as soot the OCM may not work properly
4 SOURCES - LEAKS ETC
bull Ask the group for suggestions about how to reduce the amount of oily water from leaks spills and overflows
bull Check that they understand and are following the procedures for handling items contaminated with oil - filters oily rags and so on Ask for any ideas about how to do this better
bull Stress the importance of keeping as much oil as possible out of the bilges by for example carefully emptying drip trays
bull Add any points for improvement which the group have not suggested

3 HOW THE SEPARATOR AND OIL CONTENT MONITOR WORK
Check that those taking part understand the principles of how the separator and OCM wo rk Answer any questions they may have Points to stress are
bull Separation starts in the holding tank Because oil and water have a different specific gravity the static mixture of the two liqu ids in the tank will separate with oil ris ing to the top wh ich from there can be drawn off into a waste oil tank This lowers the concentration of oil in the water towards the bottom of the tank making it eas ier for the separator to deal with

4 OPERATION OF THE SEPARATOR
The details to cover in th is secti on will obvi ously depend on the make and mode l of the separator on your sh ip Find out wh ether t he group ever experience any problems when running the equ ipment Ask for any suggestions th ey may have for im provements
You may wish to stress the following general points which were covered in the video
bull It is good practice to put the manufacturers operating instructions in an easily visible position near the separator Encourage those who operate the equipment to check the instructions even if they have used it before Sometimes even experienced operators can overlook something important
bull At the end of each cycle whoever is operating the separator should back-flush the equ ipment with clean water This cleans the filters in Stage 2 and removes any remaining oil from Stage 1 The separator should be left full at clean water so that it is ready for the next time it is used
bull At the beginning of each separat ion cycle it is important to zero test the OCM with clean water
bull At the beginning and end of each cycle it is essential to check the ship s exact posit ion as th is information must be entered in the Oil Record Book
bull On many ships [yours] there is a float in the bilge holding tank wh ich will stop the separator running before the concentration of oil in the water becomes too great for it to cope with If this is not the case on your sh ip stress that the operator should estimate the amount of pumpable water in the system so that it can be shut down before the separator is flooded with concentrated oi l It is not acceptable pract ice to run the equipment until the alarm sounds

5 MAINTENANCE
Discuss the PMS for your separator with the group
bull Check that they understand the important points which it covers
bull Find out whether they have any problems maintaining the equipment or ideas for improvement
bull Expla in how you verify that maintenance schedules are being followed
bull Stress the importance of keeping sufficient spares on board
VIDEOTEL PRODUCTIONS
Explain the key points from the fault list for your separator Stress that when faults occur
bull They must stop the separator runn ing as soon as the fault develops rather than waiting until they have identified the problem There must never be any r isk that water with an oil content above the 15 ppm Limit could be discharged overboard
bull They must avoid any temptation to break or bend the rules If a problem arises which can only be solved by doing something illegal that is an issue for the shore office to sort out
6 SECURITY
The video highlighted the use of
bull White boxes These prevent anyone tampering with the OCM
bull Seals on valves and flanges in the engine room These ensure that no one can interfere with any pipe work containing oil or oily wastes Some seals are plastic so that they can be removed quickly in an emergency Others are chains secured by padlocks The numbers of plastic seals are recorded in the engine room logbooks and the Chief Engineer keeps the keys to any padlocks
Discuss with the group the steps taken on your ship to protect the security of the equipment for handling oily water

7 THE NEW GENERATION OF SEPARATORS
As the student pointed out to the engineer in the video the current generation of separators have some important disadvantages and limitations They cope badly with dirt soot emulsifiers and oil at too high a concentration Rough sea conditions lower the efficiency of separation For these reasons it is often
difficult for even the most experienced engineers to make them work properly
That is why the IMO has introduced a revised set of gu idelines and specifications for separators These
are set out in M EPC107[491
MEPC stands for Marine Environment Protection Committee This is a committee of the International Maritime Organization - the IMO The numbers simply tell us that this is the Committee s 107th
resolution passed at their 49th session The full title of the resolution is
Revised guidelines and specifications for pollution prevention equipment for machinery spaces of ships
In addition to the usual introduction explanation of the background and definitions the resolution
contains
bull Tech nical specifications
bull Specifications for type approva l testing of pollution prevention equipment
bull Installation requirements
17
ENGINE ROOM WASTE MANAGEMENT OILY WATER ANO SEPARATORS VIOEOTEL PRODUCTIONS
These new requirements apply to
bull Installations fitted to ships the keel of which are Laid or which are at a similar stage of construction on or after 1 January 2005 and
bull To new installations fitted on or after 1 January 2005 to ships the keel of which were laid or which were at a similar stage of construction before 1 January 2005 in as far as is reasonable and practicable
The requirements for design manufacture testing type approval and so on are very detailed but tell the group that the good news for ships engineers is contained in the following single paragraph
It should be understood that a 15ppm Bilge Separator must be capable of handling any oily mixtures from the machinery space bilges and be expected to be effective over the complete range of oils which might be carried on board ship and deal with oil of very high relative density or with a mixture presented to it as an emulsion Cleansing agents emulsifiers solvents or surfactants used for cleaning purposes may cause the bilge water to emulsify Proper measures should be taken to minimise the presence of these substances in the bilges of a ship With the possibility of emulsified bilge water always present the 15ppm Bilge Separator must be capable of separating the oil from the emulsion to produce an effluent with an oil content not exceeding 15ppm
Explain that a number of manufacturers have already risen to this challenge using a variety of technical approaches including centrifuges sophisticated membranes biological systems and evaporation If your company is introducing new generation separators explain the approach on which they will be based

1 INTRODUCTION
Explain that
bull This short training programme is about oily water
bull It is in two parts This part is about where oily water comes from how to minimise its quantity and how to control its content so that the separator and oil content monitor are able to work properly Part 2 covers how the separator and oil content monitor work how to operate and maintain them simple security precautions and an outline of the new generation of separators
bull You will show them a video lasting about 15 minutes
bull You will then lead a discussion about the points raised in the video The main objective of this discussion is to identify and agree ways of handling oily water better on your ship Stress that you want their ideas and suggestions
Remind the group that the discharge of oily water whether through the separator or to shore based facilities is strictly controlled by internationally agreed regulations and it is inspected by port state authorities The limit for discharge at sea is 15ppm parts per million] and the ship must be en route during discharge
Ask them if they know what 15ppm means It is roughly a coffee cup of oil in 20m3 of water

3 POINTS FROM THE VIDEO
Ask the group what they thought were the important points from the video In summary these are
bull There are many sources of oily water - such as leaks spills overflows and condensation
bull Good housekeeping can reduce the quantity of oily water coming from many of these sources A leak that drips every second can put 30 or 40 litres into the bilges in a day
bull Cleaning is a particular issue
bull Controlling the content as well as the quantity of the oily water that reaches the bilges is important If it contains too much oil the separator may struggle to cope with it If it contains impurities such as soot the OCM may not work properly
4 SOURCES - LEAKS ETC
bull Ask the group for suggestions about how to reduce the amount of oily water from leaks spills and overflows
bull Check that they understand and are following the procedures for handling items contaminated with oil - filters oily rags and so on Ask for any ideas about how to do this better
bull Stress the importance of keeping as much oil as possible out of the bilges by for example carefully emptying drip trays
bull Add any points for improvement which the group have not suggested
9
ENGINE ROOM WASTE MANAGEMENT OILY WATER AND SEPARATORS
5 SOURCES - CLEANING
Discuss and identify improvements in the procedures for the following cleaning tasks
bull Keeping bilges and holding tanks as clean as possible
bull Preventing emulsifiers getting into the bilge water
bull Cleaning the air cooler in the charge air receiver
bull Disposing of gas oi l used for clea ning
bull Handling water contaminated with soot from pressure washing the waste heat recovery unit in the funnel wh ile in port

3 HOW THE SEPARATOR AND OIL CONTENT MONITOR WORK
Check that those taking part understand the principles of how the separator and OCM wo rk Answer any questions they may have Points to stress are
bull Separation starts in the holding tank Because oil and water have a different specific gravity the static mixture of the two liqu ids in the tank will separate with oil ris ing to the top wh ich from there can be drawn off into a waste oil tank This lowers the concentration of oil in the water towards the bottom of the tank making it eas ier for the separator to deal with
bull The present generation of separators contain two stages

4 OPERATION OF THE SEPARATOR
The details to cover in th is secti on will obvi ously depend on the make and mode l of the separator on your sh ip Find out wh ether t he group ever experience any problems when running the equ ipment Ask for any suggestions th ey may have for im provements
You may wish to stress the following general points which were covered in the video
bull It is good practice to put the manufacturers operating instructions in an easily visible position near the separator Encourage those who operate the equipment to check the instructions even if they have used it before Sometimes even experienced operators can overlook something important
bull At the end of each cycle whoever is operating the separator should back-flush the equ ipment with clean water This cleans the filters in Stage 2 and removes any remaining oil from Stage 1 The separator should be left full at clean water so that it is ready for the next time it is used
bull At the beginning of each separat ion cycle it is important to zero test the OCM with clean water
bull At the beginning and end of each cycle it is essential to check the ship s exact posit ion as th is information must be entered in the Oil Record Book
bull On many ships [yours] there is a float in the bilge holding tank wh ich will stop the separator running before the concentration of oil in the water becomes too great for it to cope with If this is not the case on your sh ip stress that the operator should estimate the amount of pumpable water in the system so that it can be shut down before the separator is flooded with concentrated oi l It is not acceptable pract ice to run the equipment until the alarm sounds
Explain and discuss any standing orders on your ship which are additional to the procedures called for in the statutory regulations
15
ENGINE ROOM WASTE MANAGEMENT OILY WATER AND SEPARATORS
5 MAINTENANCE
Discuss the PMS for your separator with the group
bull Check that they understand the important points which it covers
bull Find out whether they have any problems maintaining the equipment or ideas for improvement
bull Expla in how you verify that maintenance schedules are being followed
bull Stress the importance of keeping sufficient spares on board
VIDEOTEL PRODUCTIONS
Explain the key points from the fault list for your separator Stress that when faults occur
bull They must stop the separator runn ing as soon as the fault develops rather than waiting until they have identified the problem There must never be any r isk that water with an oil content above the 15 ppm Limit could be discharged overboard
bull They must avoid any temptation to break or bend the rules If a problem arises which can only be solved by doing something illegal that is an issue for the shore office to sort out
6 SECURITY
The video highlighted the use of
bull White boxes These prevent anyone tampering with the OCM
bull Seals on valves and flanges in the engine room These ensure that no one can interfere with any pipe work containing oil or oily wastes Some seals are plastic so that they can be removed quickly in an emergency Others are chains secured by padlocks The numbers of plastic seals are recorded in the engine room logbooks and the Chief Engineer keeps the keys to any padlocks
Discuss with the group the steps taken on your ship to protect the security of the equipment for handling oily water
16
ENGINE ROOM WASTE MANAGEMENT OILY WATER AND SEPARATORS VIDEOTEL PRODUCTIONS
7 THE NEW GENERATION OF SEPARATORS
As the student pointed out to the engineer in the video the current generation of separators have some important disadvantages and limitations They cope badly with dirt soot emulsifiers and oil at too high a concentration Rough sea conditions lower the efficiency of separation For these reasons it is often
difficult for even the most experienced engineers to make them work properly
That is why the IMO has introduced a revised set of gu idelines and specifications for separators These
are set out in M EPC107[491
MEPC stands for Marine Environment Protection Committee This is a committee of the International Maritime Organization - the IMO The numbers simply tell us that this is the Committee s 107th
resolution passed at their 49th session The full title of the resolution is
Revised guidelines and specifications for pollution prevention equipment for machinery spaces of ships
In addition to the usual introduction explanation of the background and definitions the resolution
contains
bull Tech nical specifications
bull Specifications for type approva l testing of pollution prevention equipment
bull Installation requirements
17
ENGINE ROOM WASTE MANAGEMENT OILY WATER ANO SEPARATORS VIOEOTEL PRODUCTIONS
These new requirements apply to
bull Installations fitted to ships the keel of which are Laid or which are at a similar stage of construction on or after 1 January 2005 and
bull To new installations fitted on or after 1 January 2005 to ships the keel of which were laid or which were at a similar stage of construction before 1 January 2005 in as far as is reasonable and practicable
The requirements for design manufacture testing type approval and so on are very detailed but tell the group that the good news for ships engineers is contained in the following single paragraph
It should be understood that a 15ppm Bilge Separator must be capable of handling any oily mixtures from the machinery space bilges and be expected to be effective over the complete range of oils which might be carried on board ship and deal with oil of very high relative density or with a mixture presented to it as an emulsion Cleansing agents emulsifiers solvents or surfactants used for cleaning purposes may cause the bilge water to emulsify Proper measures should be taken to minimise the presence of these substances in the bilges of a ship With the possibility of emulsified bilge water always present the 15ppm Bilge Separator must be capable of separating the oil from the emulsion to produce an effluent with an oil content not exceeding 15ppm
Explain that a number of manufacturers have already risen to this challenge using a variety of technical approaches including centrifuges sophisticated membranes biological systems and evaporation If your company is introducing new generation separators explain the approach on which they will be based

1 INTRODUCTION
Explain that
bull This short training programme is about oily water
bull It is in two parts This part is about where oily water comes from how to minimise its quantity and how to control its content so that the separator and oil content monitor are able to work properly Part 2 covers how the separator and oil content monitor work how to operate and maintain them simple security precautions and an outline of the new generation of separators
bull You will show them a video lasting about 15 minutes
bull You will then lead a discussion about the points raised in the video The main objective of this discussion is to identify and agree ways of handling oily water better on your ship Stress that you want their ideas and suggestions
Remind the group that the discharge of oily water whether through the separator or to shore based facilities is strictly controlled by internationally agreed regulations and it is inspected by port state authorities The limit for discharge at sea is 15ppm parts per million] and the ship must be en route during discharge
Ask them if they know what 15ppm means It is roughly a coffee cup of oil in 20m3 of water

3 POINTS FROM THE VIDEO
Ask the group what they thought were the important points from the video In summary these are
bull There are many sources of oily water - such as leaks spills overflows and condensation
bull Good housekeeping can reduce the quantity of oily water coming from many of these sources A leak that drips every second can put 30 or 40 litres into the bilges in a day
bull Cleaning is a particular issue
bull Controlling the content as well as the quantity of the oily water that reaches the bilges is important If it contains too much oil the separator may struggle to cope with it If it contains impurities such as soot the OCM may not work properly
4 SOURCES - LEAKS ETC
bull Ask the group for suggestions about how to reduce the amount of oily water from leaks spills and overflows
bull Check that they understand and are following the procedures for handling items contaminated with oil - filters oily rags and so on Ask for any ideas about how to do this better
bull Stress the importance of keeping as much oil as possible out of the bilges by for example carefully emptying drip trays
bull Add any points for improvement which the group have not suggested

3 HOW THE SEPARATOR AND OIL CONTENT MONITOR WORK
Check that those taking part understand the principles of how the separator and OCM wo rk Answer any questions they may have Points to stress are
bull Separation starts in the holding tank Because oil and water have a different specific gravity the static mixture of the two liqu ids in the tank will separate with oil ris ing to the top wh ich from there can be drawn off into a waste oil tank This lowers the concentration of oil in the water towards the bottom of the tank making it eas ier for the separator to deal with
bull The present generation of separators contain two stages

4 OPERATION OF THE SEPARATOR
The details to cover in th is secti on will obvi ously depend on the make and mode l of the separator on your sh ip Find out wh ether t he group ever experience any problems when running the equ ipment Ask for any suggestions th ey may have for im provements
You may wish to stress the following general points which were covered in the video
bull It is good practice to put the manufacturers operating instructions in an easily visible position near the separator Encourage those who operate the equipment to check the instructions even if they have used it before Sometimes even experienced operators can overlook something important
bull At the end of each cycle whoever is operating the separator should back-flush the equ ipment with clean water This cleans the filters in Stage 2 and removes any remaining oil from Stage 1 The separator should be left full at clean water so that it is ready for the next time it is used
bull At the beginning of each separat ion cycle it is important to zero test the OCM with clean water
bull At the beginning and end of each cycle it is essential to check the ship s exact posit ion as th is information must be entered in the Oil Record Book
bull On many ships [yours] there is a float in the bilge holding tank wh ich will stop the separator running before the concentration of oil in the water becomes too great for it to cope with If this is not the case on your sh ip stress that the operator should estimate the amount of pumpable water in the system so that it can be shut down before the separator is flooded with concentrated oi l It is not acceptable pract ice to run the equipment until the alarm sounds
Explain and discuss any standing orders on your ship which are additional to the procedures called for in the statutory regulations
15
ENGINE ROOM WASTE MANAGEMENT OILY WATER AND SEPARATORS
5 MAINTENANCE
Discuss the PMS for your separator with the group
bull Check that they understand the important points which it covers
bull Find out whether they have any problems maintaining the equipment or ideas for improvement
bull Expla in how you verify that maintenance schedules are being followed
bull Stress the importance of keeping sufficient spares on board
VIDEOTEL PRODUCTIONS
Explain the key points from the fault list for your separator Stress that when faults occur
bull They must stop the separator runn ing as soon as the fault develops rather than waiting until they have identified the problem There must never be any r isk that water with an oil content above the 15 ppm Limit could be discharged overboard
bull They must avoid any temptation to break or bend the rules If a problem arises which can only be solved by doing something illegal that is an issue for the shore office to sort out
6 SECURITY
The video highlighted the use of
bull White boxes These prevent anyone tampering with the OCM
bull Seals on valves and flanges in the engine room These ensure that no one can interfere with any pipe work containing oil or oily wastes Some seals are plastic so that they can be removed quickly in an emergency Others are chains secured by padlocks The numbers of plastic seals are recorded in the engine room logbooks and the Chief Engineer keeps the keys to any padlocks
Discuss with the group the steps taken on your ship to protect the security of the equipment for handling oily water

7 THE NEW GENERATION OF SEPARATORS
As the student pointed out to the engineer in the video the current generation of separators have some important disadvantages and limitations They cope badly with dirt soot emulsifiers and oil at too high a concentration Rough sea conditions lower the efficiency of separation For these reasons it is often
difficult for even the most experienced engineers to make them work properly
That is why the IMO has introduced a revised set of gu idelines and specifications for separators These
are set out in M EPC107[491
MEPC stands for Marine Environment Protection Committee This is a committee of the International Maritime Organization - the IMO The numbers simply tell us that this is the Committee s 107th
resolution passed at their 49th session The full title of the resolution is
Revised guidelines and specifications for pollution prevention equipment for machinery spaces of ships
In addition to the usual introduction explanation of the background and definitions the resolution
contains
bull Tech nical specifications
bull Specifications for type approva l testing of pollution prevention equipment
bull Installation requirements
17
ENGINE ROOM WASTE MANAGEMENT OILY WATER ANO SEPARATORS VIOEOTEL PRODUCTIONS
These new requirements apply to
bull Installations fitted to ships the keel of which are Laid or which are at a similar stage of construction on or after 1 January 2005 and
bull To new installations fitted on or after 1 January 2005 to ships the keel of which were laid or which were at a similar stage of construction before 1 January 2005 in as far as is reasonable and practicable
The requirements for design manufacture testing type approval and so on are very detailed but tell the group that the good news for ships engineers is contained in the following single paragraph
It should be understood that a 15ppm Bilge Separator must be capable of handling any oily mixtures from the machinery space bilges and be expected to be effective over the complete range of oils which might be carried on board ship and deal with oil of very high relative density or with a mixture presented to it as an emulsion Cleansing agents emulsifiers solvents or surfactants used for cleaning purposes may cause the bilge water to emulsify Proper measures should be taken to minimise the presence of these substances in the bilges of a ship With the possibility of emulsified bilge water always present the 15ppm Bilge Separator must be capable of separating the oil from the emulsion to produce an effluent with an oil content not exceeding 15ppm
Explain that a number of manufacturers have already risen to this challenge using a variety of technical approaches including centrifuges sophisticated membranes biological systems and evaporation If your company is introducing new generation separators explain the approach on which they will be based

That is why the IMO has introduced a revised set of gu idelines and specifications for separators These
are set out in M EPC107[491
MEPC stands for Marine Environment Protection Committee This is a committee of the International Maritime Organization - the IMO The numbers simply tell us that this is the Committee s 107th
resolution passed at their 49th session The full title of the resolution is
Revised guidelines and specifications for pollution prevention equipment for machinery spaces of ships
In addition to the usual introduction explanation of the background and definitions the resolution
contains
bull Tech nical specifications
bull Specifications for type approva l testing of pollution prevention equipment
bull Installation requirements

ENGINE ROOM WASTE MANAGEMENT OILY WATER ANO SEPARATORS VIOEOTEL PRODUCTIONS
These new requirements apply to
bull Installations fitted to ships the keel of which are Laid or which are at a similar stage of construction on or after 1 January 2005 and
bull To new installations fitted on or after 1 January 2005 to ships the keel of which were laid or which were at a similar stage of construction before 1 January 2005 in as far as is reasonable and practicable
The requirements for design manufacture testing type approval and so on are very detailed but tell the group that the good news for ships engineers is contained in the following single paragraph
It should be understood that a 15ppm Bilge Separator must be capable of handling any oily mixtures from the machinery space bilges and be expected to be effective over the complete range of oils which might be carried on board ship and deal with oil of very high relative density or with a mixture presented to it as an emulsion Cleansing agents emulsifiers solvents or surfactants used for cleaning purposes may cause the bilge water to emulsify Proper measures should be taken to minimise the presence of these substances in the bilges of a ship With the possibility of emulsified bilge water always present the 15ppm Bilge Separator must be capable of separating the oil from the emulsion to produce an effluent with an oil content not exceeding 15ppm
Explain that a number of manufacturers have already risen to this challenge using a variety of technical approaches including centrifuges sophisticated membranes biological systems and evaporation If your company is introducing new generation separators explain the approach on which they will be based

1 INTRODUCTION
Explain that
bull This short training programme is about oily water
bull It is in two parts This part is about where oily water comes from how to minimise its quantity and how to control its content so that the separator and oil content monitor are able to work properly Part 2 covers how the separator and oil content monitor work how to operate and maintain them simple security precautions and an outline of the new generation of separators
bull You will show them a video lasting about 15 minutes
bull You will then lead a discussion about the points raised in the video The main objective of this discussion is to identify and agree ways of handling oily water better on your ship Stress that you want their ideas and suggestions
Remind the group that the discharge of oily water whether through the separator or to shore based facilities is strictly controlled by internationally agreed regulations and it is inspected by port state authorities The limit for discharge at sea is 15ppm parts per million] and the ship must be en route during discharge
Ask them if they know what 15ppm means It is roughly a coffee cup of oil in 20m3 of water

3 POINTS FROM THE VIDEO
Ask the group what they thought were the important points from the video In summary these are
bull There are many sources of oily water - such as leaks spills overflows and condensation
bull Good housekeeping can reduce the quantity of oily water coming from many of these sources A leak that drips every second can put 30 or 40 litres into the bilges in a day
bull Cleaning is a particular issue
bull Controlling the content as well as the quantity of the oily water that reaches the bilges is important If it contains too much oil the separator may struggle to cope with it If it contains impurities such as soot the OCM may not work properly
4 SOURCES - LEAKS ETC
bull Ask the group for suggestions about how to reduce the amount of oily water from leaks spills and overflows
bull Check that they understand and are following the procedures for handling items contaminated with oil - filters oily rags and so on Ask for any ideas about how to do this better
bull Stress the importance of keeping as much oil as possible out of the bilges by for example carefully emptying drip trays
bull Add any points for improvement which the group have not suggested

5 SOURCES - CLEANING
Discuss and identify improvements in the procedures for the following cleaning tasks
bull Keeping bilges and holding tanks as clean as possible
bull Preventing emulsifiers getting into the bilge water
bull Cleaning the air cooler in the charge air receiver
bull Disposing of gas oi l used for clea ning
bull Handling water contaminated with soot from pressure washing the waste heat recovery unit in the funnel wh ile in port

3 HOW THE SEPARATOR AND OIL CONTENT MONITOR WORK
Check that those taking part understand the principles of how the separator and OCM wo rk Answer any questions they may have Points to stress are
bull Separation starts in the holding tank Because oil and water have a different specific gravity the static mixture of the two liqu ids in the tank will separate with oil ris ing to the top wh ich from there can be drawn off into a waste oil tank This lowers the concentration of oil in the water towards the bottom of the tank making it eas ier for the separator to deal with
bull The present generation of separators contain two stages

4 OPERATION OF THE SEPARATOR
The details to cover in th is secti on will obvi ously depend on the make and mode l of the separator on your sh ip Find out wh ether t he group ever experience any problems when running the equ ipment Ask for any suggestions th ey may have for im provements
You may wish to stress the following general points which were covered in the video
bull It is good practice to put the manufacturers operating instructions in an easily visible position near the separator Encourage those who operate the equipment to check the instructions even if they have used it before Sometimes even experienced operators can overlook something important
bull At the end of each cycle whoever is operating the separator should back-flush the equ ipment with clean water This cleans the filters in Stage 2 and removes any remaining oil from Stage 1 The separator should be left full at clean water so that it is ready for the next time it is used
bull At the beginning of each separat ion cycle it is important to zero test the OCM with clean water
bull At the beginning and end of each cycle it is essential to check the ship s exact posit ion as th is information must be entered in the Oil Record Book
bull On many ships [yours] there is a float in the bilge holding tank wh ich will stop the separator running before the concentration of oil in the water becomes too great for it to cope with If this is not the case on your sh ip stress that the operator should estimate the amount of pumpable water in the system so that it can be shut down before the separator is flooded with concentrated oi l It is not acceptable pract ice to run the equipment until the alarm sounds
Explain and discuss any standing orders on your ship which are additional to the procedures called for in the statutory regulations
15
ENGINE ROOM WASTE MANAGEMENT OILY WATER AND SEPARATORS
5 MAINTENANCE
Discuss the PMS for your separator with the group
bull Check that they understand the important points which it covers
bull Find out whether they have any problems maintaining the equipment or ideas for improvement
bull Expla in how you verify that maintenance schedules are being followed
bull Stress the importance of keeping sufficient spares on board
VIDEOTEL PRODUCTIONS
Explain the key points from the fault list for your separator Stress that when faults occur
bull They must stop the separator runn ing as soon as the fault develops rather than waiting until they have identified the problem There must never be any r isk that water with an oil content above the 15 ppm Limit could be discharged overboard
bull They must avoid any temptation to break or bend the rules If a problem arises which can only be solved by doing something illegal that is an issue for the shore office to sort out
6 SECURITY
The video highlighted the use of
bull White boxes These prevent anyone tampering with the OCM
bull Seals on valves and flanges in the engine room These ensure that no one can interfere with any pipe work containing oil or oily wastes Some seals are plastic so that they can be removed quickly in an emergency Others are chains secured by padlocks The numbers of plastic seals are recorded in the engine room logbooks and the Chief Engineer keeps the keys to any padlocks
Discuss with the group the steps taken on your ship to protect the security of the equipment for handling oily water

3 HOW THE SEPARATOR AND OIL CONTENT MONITOR WORK
Check that those taking part understand the principles of how the separator and OCM wo rk Answer any questions they may have Points to stress are
bull Separation starts in the holding tank Because oil and water have a different specific gravity the static mixture of the two liqu ids in the tank will separate with oil ris ing to the top wh ich from there can be drawn off into a waste oil tank This lowers the concentration of oil in the water towards the bottom of the tank making it eas ier for the separator to deal with
bull The present generation of separators contain two stages

4 OPERATION OF THE SEPARATOR
The details to cover in th is secti on will obvi ously depend on the make and mode l of the separator on your sh ip Find out wh ether t he group ever experience any problems when running the equ ipment Ask for any suggestions th ey may have for im provements
You may wish to stress the following general points which were covered in the video
bull It is good practice to put the manufacturers operating instructions in an easily visible position near the separator Encourage those who operate the equipment to check the instructions even if they have used it before Sometimes even experienced operators can overlook something important
bull At the end of each cycle whoever is operating the separator should back-flush the equ ipment with clean water This cleans the filters in Stage 2 and removes any remaining oil from Stage 1 The separator should be left full at clean water so that it is ready for the next time it is used
bull At the beginning of each separat ion cycle it is important to zero test the OCM with clean water
bull At the beginning and end of each cycle it is essential to check the ship s exact posit ion as th is information must be entered in the Oil Record Book
bull On many ships [yours] there is a float in the bilge holding tank wh ich will stop the separator running before the concentration of oil in the water becomes too great for it to cope with If this is not the case on your sh ip stress that the operator should estimate the amount of pumpable water in the system so that it can be shut down before the separator is flooded with concentrated oi l It is not acceptable pract ice to run the equipment until the alarm sounds
Explain and discuss any standing orders on your ship which are additional to the procedures called for in the statutory regulations
15
ENGINE ROOM WASTE MANAGEMENT OILY WATER AND SEPARATORS
5 MAINTENANCE
Discuss the PMS for your separator with the group
bull Check that they understand the important points which it covers
bull Find out whether they have any problems maintaining the equipment or ideas for improvement
bull Expla in how you verify that maintenance schedules are being followed
bull Stress the importance of keeping sufficient spares on board
VIDEOTEL PRODUCTIONS
Explain the key points from the fault list for your separator Stress that when faults occur
bull They must stop the separator runn ing as soon as the fault develops rather than waiting until they have identified the problem There must never be any r isk that water with an oil content above the 15 ppm Limit could be discharged overboard
bull They must avoid any temptation to break or bend the rules If a problem arises which can only be solved by doing something illegal that is an issue for the shore office to sort out
6 SECURITY
The video highlighted the use of
bull White boxes These prevent anyone tampering with the OCM
bull Seals on valves and flanges in the engine room These ensure that no one can interfere with any pipe work containing oil or oily wastes Some seals are plastic so that they can be removed quickly in an emergency Others are chains secured by padlocks The numbers of plastic seals are recorded in the engine room logbooks and the Chief Engineer keeps the keys to any padlocks
Discuss with the group the steps taken on your ship to protect the security of the equipment for handling oily water

7 THE NEW GENERATION OF SEPARATORS
As the student pointed out to the engineer in the video the current generation of separators have some important disadvantages and limitations They cope badly with dirt soot emulsifiers and oil at too high a concentration Rough sea conditions lower the efficiency of separation For these reasons it is often
difficult for even the most experienced engineers to make them work properly
That is why the IMO has introduced a revised set of gu idelines and specifications for separators These
are set out in M EPC107[491
MEPC stands for Marine Environment Protection Committee This is a committee of the International Maritime Organization - the IMO The numbers simply tell us that this is the Committee s 107th
resolution passed at their 49th session The full title of the resolution is
Revised guidelines and specifications for pollution prevention equipment for machinery spaces of ships
In addition to the usual introduction explanation of the background and definitions the resolution
contains
bull Tech nical specifications
bull Specifications for type approva l testing of pollution prevention equipment
bull Installation requirements
17
ENGINE ROOM WASTE MANAGEMENT OILY WATER ANO SEPARATORS VIOEOTEL PRODUCTIONS
These new requirements apply to
bull Installations fitted to ships the keel of which are Laid or which are at a similar stage of construction on or after 1 January 2005 and
bull To new installations fitted on or after 1 January 2005 to ships the keel of which were laid or which were at a similar stage of construction before 1 January 2005 in as far as is reasonable and practicable
The requirements for design manufacture testing type approval and so on are very detailed but tell the group that the good news for ships engineers is contained in the following single paragraph
It should be understood that a 15ppm Bilge Separator must be capable of handling any oily mixtures from the machinery space bilges and be expected to be effective over the complete range of oils which might be carried on board ship and deal with oil of very high relative density or with a mixture presented to it as an emulsion Cleansing agents emulsifiers solvents or surfactants used for cleaning purposes may cause the bilge water to emulsify Proper measures should be taken to minimise the presence of these substances in the bilges of a ship With the possibility of emulsified bilge water always present the 15ppm Bilge Separator must be capable of separating the oil from the emulsion to produce an effluent with an oil content not exceeding 15ppm
Explain that a number of manufacturers have already risen to this challenge using a variety of technical approaches including centrifuges sophisticated membranes biological systems and evaporation If your company is introducing new generation separators explain the approach on which they will be based

1 INTRODUCTION
Explain that
bull PART 2 of this short training programme covers how the separator and DCM work how to operate and mainta in them including tackling faults simple security precautions and an outline of the new generation of separators
bull As in PART 1 you will show them a video lasting about 15 m inutes followed by a discussion about the points raised in the video The main objective of this discussion is to identify and agree ways of handling oily water better on your ship Stress that you want their ideas and suggestions
2 THE VIDEO
Remind the group that the video shows a conversation between an engineer officer and a student who is nearing the end of her university degree course in mechanical engineering and is considering a career at sea In PART 1 they discussed the sources of oily water In this part they talk about how oily water is dealt with

3 HOW THE SEPARATOR AND OIL CONTENT MONITOR WORK
Check that those taking part understand the principles of how the separator and OCM wo rk Answer any questions they may have Points to stress are
bull Separation starts in the holding tank Because oil and water have a different specific gravity the static mixture of the two liqu ids in the tank will separate with oil ris ing to the top wh ich from there can be drawn off into a waste oil tank This lowers the concentration of oil in the water towards the bottom of the tank making it eas ier for the separator to deal with
bull The present generation of separators contain two stages

4 OPERATION OF THE SEPARATOR
The details to cover in th is secti on will obvi ously depend on the make and mode l of the separator on your sh ip Find out wh ether t he group ever experience any problems when running the equ ipment Ask for any suggestions th ey may have for im provements
You may wish to stress the following general points which were covered in the video
bull It is good practice to put the manufacturers operating instructions in an easily visible position near the separator Encourage those who operate the equipment to check the instructions even if they have used it before Sometimes even experienced operators can overlook something important
bull At the end of each cycle whoever is operating the separator should back-flush the equ ipment with clean water This cleans the filters in Stage 2 and removes any remaining oil from Stage 1 The separator should be left full at clean water so that it is ready for the next time it is used
bull At the beginning of each separat ion cycle it is important to zero test the OCM with clean water
bull At the beginning and end of each cycle it is essential to check the ship s exact posit ion as th is information must be entered in the Oil Record Book
bull On many ships [yours] there is a float in the bilge holding tank wh ich will stop the separator running before the concentration of oil in the water becomes too great for it to cope with If this is not the case on your sh ip stress that the operator should estimate the amount of pumpable water in the system so that it can be shut down before the separator is flooded with concentrated oi l It is not acceptable pract ice to run the equipment until the alarm sounds
Explain and discuss any standing orders on your ship which are additional to the procedures called for in the statutory regulations
15
ENGINE ROOM WASTE MANAGEMENT OILY WATER AND SEPARATORS
5 MAINTENANCE
Discuss the PMS for your separator with the group
bull Check that they understand the important points which it covers
bull Find out whether they have any problems maintaining the equipment or ideas for improvement
bull Expla in how you verify that maintenance schedules are being followed
bull Stress the importance of keeping sufficient spares on board
VIDEOTEL PRODUCTIONS
Explain the key points from the fault list for your separator Stress that when faults occur
bull They must stop the separator runn ing as soon as the fault develops rather than waiting until they have identified the problem There must never be any r isk that water with an oil content above the 15 ppm Limit could be discharged overboard
bull They must avoid any temptation to break or bend the rules If a problem arises which can only be solved by doing something illegal that is an issue for the shore office to sort out
6 SECURITY
The video highlighted the use of
bull White boxes These prevent anyone tampering with the OCM
bull Seals on valves and flanges in the engine room These ensure that no one can interfere with any pipe work containing oil or oily wastes Some seals are plastic so that they can be removed quickly in an emergency Others are chains secured by padlocks The numbers of plastic seals are recorded in the engine room logbooks and the Chief Engineer keeps the keys to any padlocks
Discuss with the group the steps taken on your ship to protect the security of the equipment for handling oily water

7 THE NEW GENERATION OF SEPARATORS
As the student pointed out to the engineer in the video the current generation of separators have some important disadvantages and limitations They cope badly with dirt soot emulsifiers and oil at too high a concentration Rough sea conditions lower the efficiency of separation For these reasons it is often
difficult for even the most experienced engineers to make them work properly
That is why the IMO has introduced a revised set of gu idelines and specifications for separators These
are set out in M EPC107[491
MEPC stands for Marine Environment Protection Committee This is a committee of the International Maritime Organization - the IMO The numbers simply tell us that this is the Committee s 107th
resolution passed at their 49th session The full title of the resolution is
Revised guidelines and specifications for pollution prevention equipment for machinery spaces of ships
In addition to the usual introduction explanation of the background and definitions the resolution
contains
bull Tech nical specifications
bull Specifications for type approva l testing of pollution prevention equipment
bull Installation requirements
17
ENGINE ROOM WASTE MANAGEMENT OILY WATER ANO SEPARATORS VIOEOTEL PRODUCTIONS
These new requirements apply to
bull Installations fitted to ships the keel of which are Laid or which are at a similar stage of construction on or after 1 January 2005 and
bull To new installations fitted on or after 1 January 2005 to ships the keel of which were laid or which were at a similar stage of construction before 1 January 2005 in as far as is reasonable and practicable
The requirements for design manufacture testing type approval and so on are very detailed but tell the group that the good news for ships engineers is contained in the following single paragraph
It should be understood that a 15ppm Bilge Separator must be capable of handling any oily mixtures from the machinery space bilges and be expected to be effective over the complete range of oils which might be carried on board ship and deal with oil of very high relative density or with a mixture presented to it as an emulsion Cleansing agents emulsifiers solvents or surfactants used for cleaning purposes may cause the bilge water to emulsify Proper measures should be taken to minimise the presence of these substances in the bilges of a ship With the possibility of emulsified bilge water always present the 15ppm Bilge Separator must be capable of separating the oil from the emulsion to produce an effluent with an oil content not exceeding 15ppm
Explain that a number of manufacturers have already risen to this challenge using a variety of technical approaches including centrifuges sophisticated membranes biological systems and evaporation If your company is introducing new generation separators explain the approach on which they will be based

The details to cover in th is secti on will obvi ously depend on the make and mode l of the separator on your sh ip Find out wh ether t he group ever experience any problems when running the equ ipment Ask for any suggestions th ey may have for im provements
You may wish to stress the following general points which were covered in the video
bull It is good practice to put the manufacturers operating instructions in an easily visible position near the separator Encourage those who operate the equipment to check the instructions even if they have used it before Sometimes even experienced operators can overlook something important
bull At the end of each cycle whoever is operating the separator should back-flush the equ ipment with clean water This cleans the filters in Stage 2 and removes any remaining oil from Stage 1 The separator should be left full at clean water so that it is ready for the next time it is used
bull At the beginning of each separat ion cycle it is important to zero test the OCM with clean water
bull At the beginning and end of each cycle it is essential to check the ship s exact posit ion as th is information must be entered in the Oil Record Book
bull On many ships [yours] there is a float in the bilge holding tank wh ich will stop the separator running before the concentration of oil in the water becomes too great for it to cope with If this is not the case on your sh ip stress that the operator should estimate the amount of pumpable water in the system so that it can be shut down before the separator is flooded with concentrated oi l It is not acceptable pract ice to run the equipment until the alarm sounds
Explain and discuss any standing orders on your ship which are additional to the procedures called for in the statutory regulations

bull Check that they understand the important points which it covers
bull Find out whether they have any problems maintaining the equipment or ideas for improvement
bull Expla in how you verify that maintenance schedules are being followed
bull Stress the importance of keeping sufficient spares on board
VIDEOTEL PRODUCTIONS
Explain the key points from the fault list for your separator Stress that when faults occur
bull They must stop the separator runn ing as soon as the fault develops rather than waiting until they have identified the problem There must never be any r isk that water with an oil content above the 15 ppm Limit could be discharged overboard
bull They must avoid any temptation to break or bend the rules If a problem arises which can only be solved by doing something illegal that is an issue for the shore office to sort out
6 SECURITY
The video highlighted the use of
bull White boxes These prevent anyone tampering with the OCM
bull Seals on valves and flanges in the engine room These ensure that no one can interfere with any pipe work containing oil or oily wastes Some seals are plastic so that they can be removed quickly in an emergency Others are chains secured by padlocks The numbers of plastic seals are recorded in the engine room logbooks and the Chief Engineer keeps the keys to any padlocks
Discuss with the group the steps taken on your ship to protect the security of the equipment for handling oily water

7 THE NEW GENERATION OF SEPARATORS
As the student pointed out to the engineer in the video the current generation of separators have some important disadvantages and limitations They cope badly with dirt soot emulsifiers and oil at too high a concentration Rough sea conditions lower the efficiency of separation For these reasons it is often
difficult for even the most experienced engineers to make them work properly
That is why the IMO has introduced a revised set of gu idelines and specifications for separators These
are set out in M EPC107[491
MEPC stands for Marine Environment Protection Committee This is a committee of the International Maritime Organization - the IMO The numbers simply tell us that this is the Committee s 107th
resolution passed at their 49th session The full title of the resolution is
Revised guidelines and specifications for pollution prevention equipment for machinery spaces of ships
In addition to the usual introduction explanation of the background and definitions the resolution
contains
bull Tech nical specifications
bull Specifications for type approva l testing of pollution prevention equipment
bull Installation requirements
17
ENGINE ROOM WASTE MANAGEMENT OILY WATER ANO SEPARATORS VIOEOTEL PRODUCTIONS
These new requirements apply to
bull Installations fitted to ships the keel of which are Laid or which are at a similar stage of construction on or after 1 January 2005 and
bull To new installations fitted on or after 1 January 2005 to ships the keel of which were laid or which were at a similar stage of construction before 1 January 2005 in as far as is reasonable and practicable
The requirements for design manufacture testing type approval and so on are very detailed but tell the group that the good news for ships engineers is contained in the following single paragraph
It should be understood that a 15ppm Bilge Separator must be capable of handling any oily mixtures from the machinery space bilges and be expected to be effective over the complete range of oils which might be carried on board ship and deal with oil of very high relative density or with a mixture presented to it as an emulsion Cleansing agents emulsifiers solvents or surfactants used for cleaning purposes may cause the bilge water to emulsify Proper measures should be taken to minimise the presence of these substances in the bilges of a ship With the possibility of emulsified bilge water always present the 15ppm Bilge Separator must be capable of separating the oil from the emulsion to produce an effluent with an oil content not exceeding 15ppm
Explain that a number of manufacturers have already risen to this challenge using a variety of technical approaches including centrifuges sophisticated membranes biological systems and evaporation If your company is introducing new generation separators explain the approach on which they will be based

bull They must stop the separator runn ing as soon as the fault develops rather than waiting until they have identified the problem There must never be any r isk that water with an oil content above the 15 ppm Limit could be discharged overboard
bull They must avoid any temptation to break or bend the rules If a problem arises which can only be solved by doing something illegal that is an issue for the shore office to sort out
6 SECURITY
The video highlighted the use of
bull White boxes These prevent anyone tampering with the OCM
bull Seals on valves and flanges in the engine room These ensure that no one can interfere with any pipe work containing oil or oily wastes Some seals are plastic so that they can be removed quickly in an emergency Others are chains secured by padlocks The numbers of plastic seals are recorded in the engine room logbooks and the Chief Engineer keeps the keys to any padlocks
Discuss with the group the steps taken on your ship to protect the security of the equipment for handling oily water

7 THE NEW GENERATION OF SEPARATORS
As the student pointed out to the engineer in the video the current generation of separators have some important disadvantages and limitations They cope badly with dirt soot emulsifiers and oil at too high a concentration Rough sea conditions lower the efficiency of separation For these reasons it is often
difficult for even the most experienced engineers to make them work properly
That is why the IMO has introduced a revised set of gu idelines and specifications for separators These
are set out in M EPC107[491
MEPC stands for Marine Environment Protection Committee This is a committee of the International Maritime Organization - the IMO The numbers simply tell us that this is the Committee s 107th
resolution passed at their 49th session The full title of the resolution is
Revised guidelines and specifications for pollution prevention equipment for machinery spaces of ships
In addition to the usual introduction explanation of the background and definitions the resolution
contains
bull Tech nical specifications
bull Specifications for type approva l testing of pollution prevention equipment
bull Installation requirements

bull To new installations fitted on or after 1 January 2005 to ships the keel of which were laid or which were at a similar stage of construction before 1 January 2005 in as far as is reasonable and practicable
The requirements for design manufacture testing type approval and so on are very detailed but tell the group that the good news for ships engineers is contained in the following single paragraph
It should be understood that a 15ppm Bilge Separator must be capable of handling any oily mixtures from the machinery space bilges and be expected to be effective over the complete range of oils which might be carried on board ship and deal with oil of very high relative density or with a mixture presented to it as an emulsion Cleansing agents emulsifiers solvents or surfactants used for cleaning purposes may cause the bilge water to emulsify Proper measures should be taken to minimise the presence of these substances in the bilges of a ship With the possibility of emulsified bilge water always present the 15ppm Bilge Separator must be capable of separating the oil from the emulsion to produce an effluent with an oil content not exceeding 15ppm
Explain that a number of manufacturers have already risen to this challenge using a variety of technical approaches including centrifuges sophisticated membranes biological systems and evaporation If your company is introducing new generation separators explain the approach on which they will be based

The requirements for design manufacture testing type approval and so on are very detailed but tell the group that the good news for ships engineers is contained in the following single paragraph
It should be understood that a 15ppm Bilge Separator must be capable of handling any oily mixtures from the machinery space bilges and be expected to be effective over the complete range of oils which might be carried on board ship and deal with oil of very high relative density or with a mixture presented to it as an emulsion Cleansing agents emulsifiers solvents or surfactants used for cleaning purposes may cause the bilge water to emulsify Proper measures should be taken to minimise the presence of these substances in the bilges of a ship With the possibility of emulsified bilge water always present the 15ppm Bilge Separator must be capable of separating the oil from the emulsion to produce an effluent with an oil content not exceeding 15ppm
Explain that a number of manufacturers have already risen to this challenge using a variety of technical approaches including centrifuges sophisticated membranes biological systems and evaporation If your company is introducing new generation separators explain the approach on which they will be based
