1- STRUCTURE

The KOBELCO COMPACT SEAL is composed of an AFT SEAL, which prevents stern tubelubricant oil leakage outside the ship as well as seawater from entering the stern tube, anda FORWARD SEAL which prevents stern tube lubricant oil leakage into the engine room.There is also a Double Security Type aft seal with a built-in back-up seal.

1.1 AFT SEALThe AFT SEAL can be broadly divided into the casing, which is fixed to the hull, and the

chrome steel liner, which is fixed to the propeller boss and rotates with the propeller shaft.The casing is composed of three kinds of metal rings; flange ring, intermediate ring andcover ring, which are tightened to each other with bolts. Three or four sealing rings areassembled between the metal rings with their pointed ends (lip section) touching thechrome steel liner. The lips are pressed hard against the rotating liner and maintain asealing effect through water pressure, oil pressure, elasticity of the sealing ring andtightening force of the springs.

The sealing rings are numbered 1, 2, 3, and 3S in order from the seawater side. The No.1and No.2 sealing rings close out seawater, while the No.1 sealing ring also has the functionof protecting the inside of the stern tube from foreign matter in the seawater. Lubricant oilin the stern tube is sealed in with the No.3 sealing ring.

STANDARD TYPE (3 Seals))

3

(DOUBLE SECURITY TYPE (4 Seals))

The Double Security Type has an additional construction of the No.3S sealing ring and the No.3intermediate ring on the Standard Type. If the No.3 sealing ring is damaged, the No.3S sealingring can be immediately brought into service by closing the valves on the oil lines to the oil chamberbetween the No.3 and No.3S sealing rings.

Oil Chamber Between No.3 andNo.3S Sealing Rings

In the AFT Seal Oil Supply System, oil piping is constructed to connect the engine room to theoil chamber between the No.2 and No.3 sealing rings on the AFT SEAL. (This piping is adaptablefor both Standard Type and Double Security Type seals as an option.)

(AFT Seal Oil Supply System)

Tank for Oil Chamberbetween No.2 and No.3Sealing Rings

1.2 FORWARD SEALThe FORWARD SEAL is of similar construction to the AFT SEAL except that it is

composed of two sealing rings. The sealing rings are numbered 4 and 5 in order from thestern tube. The No.4 sealing ring seals the lubricant oil in the stern tube. The forwardchrome steel liner is tightened with bolts to the split clamp ring mounted to the propellershaft.

1.3 SEALINGAll KOBELCO COMPACT SEALS are the same shape and are available in two types of

material; VITON (flororic rubber) and NBR (nitrile-butadiene rubber). VITON sealing ringshave particularly excellent heat resistant properties.

The shape of our sealing rings has a unique KOBELCO design. Therefore, be sure torequest KOBELCO COMPACT SEALS when you replace sealing rings for maintenance orrepair.

2. LUBRICATION

2.1 LUBRICANT OILRefer to the list of recommended lubricant oils on pages 18

and 19 to select an appropriate lubricant oil for the stern tubebearings.

The lubricant oils in the list have been confirmed asapplicable for our sealing rings. However, confirmation testswill be made on request for lubricant oils not listed.The appropriate lubricant oil viscosity is approximately SAE 30.

2.2 OILING2.2.1. Stern Tube

There are two methods for oiling the stern tube; through gravity tank(s) or by forcedcirculation with pumps.

FOLLOW

CAUTION

Set the oiling pressure 0.30kg/cm2 higher than the seawater pressure appliedto the center of the shaft at full load conditions.

In cases where both high and low level tanks are provided, use the high tankfor deep draft conditions and the low tank in shallow draft conditions. Followthe operating instructions for the stern tube lubrication system published bythe shipbuilder for switching over from the high and low level tanks.

For the Low Pressure System, the stern tube lubricant oil pressure can be theCAUTION same or lower than the seawater pressure (Pst<=Psw). Check the builder's

instructions for the lubrication system before use.

2.2.2. Aft Seal* In the case where there is no oil piping from the engine room to the oil chamber betweenthe No.2 and No.3 sealing rings in the AFT SEAL, feed lubricant oil during docking to the No.1/2 and No.2/3 sealing chambers through the oiling holes on the No.1 and No.2 intermediaterings. (AFT Seal Oil Supply-None. See Cover.)

In the case where oil piping is installed, the oiling pressure must beFOLLOW maintained at least 0.30kg/cm2 lower than the seawater pressure applied to

the center of the shaft under the actual aft draft. (See cover: AFT Seal OilSupply-Exist.)

Accordingly, it is also necessary to change the oiling pressure with changesin the aft draft due to loading conditions. For details, refer to the operatinginstructions published by the shipbuilder. Feed lubricant oil to the oil chamberbetween the No.1 and No.2 sealing rings before undocking through the No.1intermediate ring oiling hole.

6

2.2.3 FORWARD SEAL* There are two methods for oiling the chamber betweenthe No.4 and No.5 sealing rings on the FORWARD SEAL:gravity tank and forced circulation method.

In the case of the gravity tank method, acirculator is installed in the chamber between

FOLLOW the No.4 and No.5 sealing rings. Set the oillevel400mm - 500mm higher than the top of the casingfor the circulation of the lubricant oil. If thesetting position is too high it may causeinsufficient circulation.

CAUTION Observe the oil level and add or remove oil as necessary.

In the case of the forced circulation method, generally, the FORWARD SEALreceives oil through a line that branches off of the main oiling line to the stern

CAUTION tube. However, for smooth circulation, the valve (orifice) of the branch linemust be checked to see that the pressure is not too high or low. Also, checkthe oil circulation in the sight glass.

2.3 OIL PRESSURE TEST* After flushing the stern tube and piping system, close the stern tube drain valveand feed lubricant oil to the stern tube.

In cases where both high and low level tanks are installed, use the low level tank.

<Procedure for Standard Type seal>(1) Feed oil from the tank to the stern tube.(2) Open the drain plugs for the oil chamber between the No.2 and No.3 sealing rings

for the AFT SEAL and the No.4 and No.5 sealing rings for the FORWARD SEAL, andcheck for any oil leakage.

(3) Feed oil to the oil chamber between the No.1 and the No.2 sealing rings on the AFT SEAL.(4) Check for any leakage from the No.1 sealing ring and the drain plug for the #2 /3 oil

chamber.(5) Close the drain plug for the oil chamber between the No.2 and No.3 sealing rings and

CAUTION feed oil into the chamber. Check that the oil level does not drop below the top plug.In the case of the AFT Seal Oil Supply system, conduct oiling with the valve on theoiling line open. However, close the valve after oiling. Otherwise, rear leakage mayoccur from the No.2 sealing ring if the oil pressure is high.

(6) Close the drain plug for the #4/5 oil chamber and feed oil to the chamber.(7) Check for any leakage from the No.5 sealing ring and the vicinity of the clamp ring.

Tank for Oil Chamber betweenNo.2 and No.3 Sealing Rings

7

<Procedure for Double Security Type seal>

(1) Feed oil from the tank to the stem tube. (The valve on the #3/3S oiling line must be closed.)

(2) Open the drain plugs for the #3/3S oil chamber on the AFT SEAL and the #4/5 oil

chamber on the FORWARD SEAL and check for any leakage.

(3) Close the drain plug for the #3/3S oil chamber on the AFT SEAL, then open the valve

on the #3/3S oiling line to feed oil into the #3/3S oil chamber.

(4) Open the drain plug for the #2/3 oil chamber and check for leakage from the hole.

(5) Feed oil to the #1/2 oil chamber on the AFT SEAL.

(6) Check for any leakage from the No.1 sealing ring and the drain plug for the #2/3 oil chamber.

(7) Close the drain plug on the #2/3 oil chamber and feed oil to the chamber. Check that

the oil level does not drop below the top plug.

In the case of the AFT Seal Oil Supply, conduct oiling with the valve on the oiling lineopen.

CAUTION Close the valve after oiling. Otherwise, oil leakage may occur from the No.2 sealing

ring if the oil pressure is high.

(8) Close the drain plug on the #4/5 oil chamber and feed oil to the chamber.

(9) Check for any leakage from the No.5 sealing ring and the vicinity of the clamp ring.

CAUTION * In the case where there is a large leakage, it is important to investigate thecause.After completing the oil pressure test, check that all plugs are completelytightened and secure them with locking wire.

3. WEAR-DOWN GAUGE

The wear-down gauge is used to indirectlydetermine whether there is an abnormalitywith the stern tube bearing metal bymeasuring the variation in the clearancebetween the stern tube bearing and propellershaft. Measurements are taken at the oilinghole (TOP) and drain hole (BOTTOM) of the AFTSEAL. The initial measurement is taken uponcompletion of the ship building with theshafting, propellers and seals fully installed.Measurements thereafter should be takenduring docking and the value measured should becompared with previous measurements. When the seals are opened or the shaft is removedmeasurements should be taken before and after opening the seals. All measurements are takenwith a regular turning position; such as the No.1 cylinder piston of the main engine in the topposition, or "A" blade of the propeller in the top position.

When the chrome steel liner is skimmed with the shaft removed, the beforeCAUTION and after values will increase the amount of the skimming.

CAUTION

It is important to take measurements in the same position at all times.Alignment marks are on the oiling and drain holes for measurement.Alignment marks are also on the wear-down gauge. Conduct measurementswith both marks aligned.

CAUTION Remove the copper packing for measurement.

<Underwater inspection specifications>There is a hole on the covering for measuring wear down. All other items

are the same as above. Divers should use the special spanner included in theaccessory tools for underwater inspections.

4. REPAIR

After a long period of use the seals will require repair such as replacement of sealing rings orother parts due to the wear on sealing rings and chrome steel liners. Repair methods includereplacement repair and bonding repair where sealing rings are replaced as an emergencymeasure.

4.1 REPLACEMENT REPAIRReplacement of seals is generally done during docking when the propeller and propeller

shaft have been removed. After the seal housing has been detached from the hull, thesealing rings, chrome steel liners and other parts are replaced or repaired.Replacement of seals can recover functions similar to new. The aft and forward chromesteel liners can be reused by repeated skimming until the allowable limit shown in the tablebelow. When there is no skimming allowance remaining, the liner must be replaced.

For repair, it is possible to skim the aft and forwardchrome steel liners until the diameter D-X.*For example in the case of a 600 type, D=600, X=3.7.Therefore, D-X=600-3.7=596.3mm. It is possible to skim the linerdown to 596.3mm.

CAUTION Check that "stainless" steel bolts are used for aftseals when reassembling at repair yards or docks.

After reattaching the sealing rings to the ship, adjust the alignments in accordance with the tablebelow.

4.2 BONDING REPAIRGenerally done while the ship is in dock, bonding repair is the method of replacing the

sealing rings with the shaft and the propeller in place by vulcanizing the new sealing ringsusing a special bonding device while the ship is generally in dock. This method eliminatesthe need to move the propeller or propeller shaft to replace the sealing rings and allowsemergency repair of the aft and forward sealing rings in a short time. Bonding repairs arecarried out by KOBELCO MARINE ENGINEERING or its authorized agents.

Bonding Device

To conduct bonding repairs on the AFT SEAL while afloat, it is necessary to raise the hullto the bow in trim and propeller shaft approximately 1 meter above sea level. It alsorequires the construction of scaffolding at least 300mm above sea level.

7. POINTS THAT MUST BE FOLLOWED

FOLLOW!

During installation:* Check alignments of the seal to the hull.* Make sure waste, dust, paint, etc. do not enter theseal.

* Do not cause shock to the seal.* Do not put heavy items on top of the seal.* Do not expose the seal to high temperatures when welding etc.

Before oiling:* Flush out any waste, dust, paint, etc. from the piping.* Do not use volatile oils such as gasoline or toluene for cleaning sealing rings.

Before turning shaft:

* Fill the sealing system with the designated lubricant oil. (Refer to the recommendedlubricant oil list on pages 18 and 19.)

* Set the oil pressure of each part as designated. (Refer to the piping diagram andoperating instructions published by the shipbuilder.)

For dry-docking:

* When using the AFT Seal Oil Supply, close the valve on the oil supply line. (When theseawater pressure decreases, the lubricant oil in the #2/3 oil chamber may leak outsidethe ship due to the lack of seawater pressure.)

Requesting bonding repair:* When the seal requires bonding repair, ask for "KOBELCO MARINEENGINEERING" or its authorized agent.

16

8. USEFUL HINTS

REFERENCE

• Use of Distance Ring:

Generally grooves are generated orgrow on the outer diameter surface ofthe chrome steel liner due to friction withthe sealing rings. At times of bonding repair,the presence of such grooves may result inthe sealing ring not working properly. In suchcases it is recommended that a distance ringbe installed so that the sealing ring can be

Ipositioned in an area where there are no grooves.(Removing a distance ring that was installed during new shipbuilding will have the same effect.)

The attachment and removal of distance rings will affect the length of theflange bolt. Therefore, make sure to use an appropriate bolt. Further, distance

CAUTION rings should be Cleaned and protected with an anti-rust treatment afterremoval and stored carefully together with the bolt.

For the Forward Seal, the point of friction of the sealing ring can be changedby moving the set position of the clamp ring.

• Net StopperThe Net Stopper protects the No.1 sealing ring from fishing nets, shells etc. It is necessary to

renew the rubber stopper contained in the net stopper.
