15 ACCOMMODATION GENERAL 150 GENERAL 150.0 General Guidelines As stated in the introduction to Main Group (MGp) 5, the standard set-up/structure established for “Super-Man” has been followed as far as practical also for the accommodation Groups. This implies that the Groups (Gps) 50-58 with corresponding Sub-Groups (SGps), follow the subdivision and contents given in the applied “SFI Group System”. However, several important aspects related to accommodation matters for ships in general, have no natural “home” in MGp 5 of the standard Group System. These general items have therefore been dealt with under MGp 1, where matters of a more general nature have been gathered. General items concerning the accommodation have thus been given in Gp 15, which should therefore be studied in connection with MGp 5. Hence, Gp 15 deals with general items of importance when planning and designing the accommodation, as well as settling the main parameters being decisive for to what extent the accommodation area will fulfil certain basic requirements. These requirements apply to: * Safety * Comfort * Low maintenance cost * Easy communication and transport * Reasonable investment cost * Otherwise practical and tailor-made to the intended use On the above basis Gp 15 has been structured to contain the following Sub-Groups (SGps): * 150 - General * 151 - Location and arrangement of the accommodation * 152 - Space and size requirements * 153 - Vibrations * 154 - Noise * 155 - Material requirements * 156 - Hygiene and cleaning * 157 - Construction systems/elements * 158 - General considerations concerning the accommodation area * 159 - Misc. accommodation details Figures and sketches are located at the end of Gp 15. 150.01 Abbreviations and Definitions Following abbreviations have been used in Main Group (MGp) 5: * ABS : American Bureau of Shipping * CBT : Computer based training

When writing a specification, a special list should be made of spaces to be air-conditioned, ref. MGp 5/Gp 57. When planning a new vessel, optimisation of the cargo area and the cargo handling equipment will naturally be given priority, same for the engine room arrangement and all safety- and manoeuvring equipment. To some extent, practical layout of mooring- and other deck equipment will also have to be planned at the expense of an optimum accommodation. However, there are still numerous important matters and details concerning the accommodation that can be planned and executed in a satisfactory manner, without hampering the earning capacity of the vessel. Such items are outlined in the following. Guidelines given in Gp 15 are generally based on a ship design with all accommodation aft. However, most of the comments and recommendations given with regard to practical layout


3

and details are also applicable to vessels with accommodation forward (Ro/Ro, etc.) or in other positions, e.g. on top deck (car carriers). 151.1 Maritime Authorities/Class 151.10 General When designing and building the accommodation, compliance with applicable rules and conventions must be ensured. The same applies to quality of equipment, materials and workmanship. In addition to durability and easy cleaning of surface materials, the most important requirements for divisions, doors, ceilings, hatches and floorings are fire class and sound reduction. Suppliers should present certification for such properties as fire and sound reduction capability. Certification according to MED is the common fire and quality certification for all vessels sailing under EU/EC flag, and thus represents the preferred documentation. MED-certificates are issued by “Notified bodies” (i.e. a rather large number of institutions approved by the European Union/Community, which are too numerous to list here, but may probably be found on the Internet). The ABS “Guide for Crew Habitability on Ships” (“CrewHab”) gives ABS’ requirements for this special class notation, which as such may be considered an expensive and unnecessary refinement, but the pamphlet gives practical standards on most accommodation criteria and will thus constitute a useful platform during specification discussions. (For passenger ships there is a similar pamphlet termed “Guide for Passenger Comfort on Ships”). For material requirements see SGp 155. 151.2 Planning of Layout/Arrangement 151.20 General The engine casing with exhaust up-take and funnel should if possible be separated from and arranged aft of the accommodation area. The same applies to engine room ventilation. Precautions should be taken to prevent downdraft of soot and exhaust to the accommodation. On the lower accommodation deck, and where accommodation bulkheads are adjacent to engine room or casing, special care should be taken to reduce noise and vibrations. The area available for erecting the superstructure containing the accommodation is, in particular for smaller vessels, often more limited than desirable. Building high is normally possible, but should not exceed what is necessary to ensure prescribed view from the navigating bridge. Height of shore based bridge spans and power lines in intended trading areas must be carefully checked to ensure clearance for radar/signal mast placed on top of the deck house. A special lowering arrangement for the (top of the) mast may prove necessary.


4

An optimum layout of the accommodation may also depend on the chosen lifeboat arrangement and related escape routes. The preferred solution today (2002) is often to have one free-fall lifeboat aft which simplifies the arrangement. For details see MGp 5/Gp 50. There shall be at least two exits to escape routes leading in different directions from each level in the living quarters and at least one internal stairway linking all levels. All public rooms exceeding 20 m2 should (as far as possible) have at least two escape ways from opposite sides of the room with doors to open outwards. (Technical rooms may have hatches 800×800 mm). When planning the crew accommodation area and layout, following must be taken into account: * Number and ranks of manning * Personnel policy and social relations on board * Sailing periods and relieving arrangements * Spare accommodation for pilot(s), travelling squads, Suez crew, clients, agents, family

visits, etc. During this part of the planning phase a “contact analysis diagram” may prove useful to check and visualise internal transport and the frequency of communication between the various personnel categories. This may help to find an optimum location of working areas, living quarters and leisure areas in relation to each other. At an early planning stage it might also be possible to influence the steel structure to ensure optimum dimensions of cabins etc. 151.3 Arrangement of Technical Systems 151.30 General When the various main systems are arranged in a systematic manner and, as far as relevant, at the same locations on the various decks, this will facilitate construction and the crew’s knowledge of the vessel. This applies to main stairways, sanitary- and electrical equipment, ventilation ducts, etc. For details see the respective Groups/Sub-Groups of MGp 5. 151.4 Wind Resistance 151.40 General This may be somewhat reduced by rounding the corners and inclining the front of the deck house. However, for ordinary cargo vessels, fuel savings will be minimal in comparison to the increase in building cost. It is therefore more viable to arrange “spoilers” at the aft end of the deck house, e.g. in the shape of a vertical trunk for exhaust pipes and/or ventilation ducts, located at the centre of the aft end wall to break up the single, big slipstream vortex.

152 SPACE AND SIZE REQUIREMENTS 152.0 General Guidelines Accommodation requirements for sea-going ships above 1000 GRT are basically ruled by the ILO Convention No. 92 – “Convention concerning Crew Accommodation on Board Ships” (Revised 1949) and Convention No. 133 (Supplementary Provisions) of 1970, the essence of which is given below. It should be noted, however, that these regulations constitute a bare minimum and that most accommodations nowadays (year 2002) provide more spacious layouts for the well being of officers and crew. One may therefore state that the ILO Conventions in many respects are somewhat out of date. The Norwegian Maritime Directorate’s (NMD) regulations (Sect. 18) are also on certain points exceeding the ILO minimum. In this regard it should be noted that crew’s living quarters and working areas generally are quite strictly regulated by the various flag states. Unfortunately, the practical implications of their rules may vary quite a lot. (See also 151.1 – ABS’ Guide). In spite of this, it may be of interest to the users of “Super-Man” that an overview of the ILO requirements is given in this Manual. The following description is therefore generally based on the ILO minimum requirements. However, the proposed cabin layouts and sizes are not related to ILO, but are meant to serve as a guideline for how cabins may be arranged on modern vessels. As a general rule, each crewmember (above 18 of age) should have a separate cabin (does not apply to passenger vessels). In ships of 3.000 GRT and above, the senior officers shall in addition have an adjoining day/sitting-room. The ILO minimum floor area for ratings’ separate cabins is: * 1000 - 3000 GRT : 3,75 m2

* 3000 - 10.000 GRT: 4,25 m2 * Above 10.000 GRT: 4,75 m2 Cabins for (a maximum of) two ratings require 0,5 m2 less than the above figures for each person. Cabins for officers where no adjoining day room is provided, should be minimum 6,5 m2 for ships below 3.000 GRT and 7,5 m2 for ships above. The distance from bedside to opposite bulkhead never to be less than 700 mm. Space occupied by berths, lockers, chest of drawers, seats and tables shall be included in the above areas. Minimum inside dimensions of a berth shall be 2000 mm x 800 mm. (Note: Standard mattress lengths are 2000 and 2010 mm). A reading lamp to be installed at the head of each berth.


6

The floor area of mess rooms for officers and for ratings shall not be less than 1 m2 per person of the planned seating capacity. Number of seats must be sufficient to accommodate the greatest number of crewmembers likely to use them at any time. Recreation rooms are also to be provided for officers and ratings. If such rooms are not provided separately (as required for ships above 8000 GRT), they may be incorporated in the mess room(s). Such facilities shall as a minimum include a bookcase, facilities for reading, writing and for games. A swimming pool “should be considered”. It should also be possible to watch TV and video. On ships between 5000 and 15.000 GRT at least five officer’s cabins shall have attached a separate, private bathroom with shower, toilet and wash basin. In addition, on ships above 10.000 but less than 15.000 GRT, the cabins for all other officers shall have common, intercommunicating bathrooms between two adjacent cabins similarly equipped, whereas on ships above 15.000 GRT all officers to have private bathrooms attached. On ships above 25.000 GRT a separate bathroom equipped as above for every two ratings shall be provided, preferably as an intercommunicating room between two adjacent cabins or just across the corridor. Otherwise, on all ships, a minimum of one toilet/water closet and one shower to be provided for each six persons or less, who have not been provided with separate facilities. Such persons also to have a wash basin installed in each cabin. One water closet and wash basin should be arranged within easy access from the navigation bridge, and one likewise from the engine room. One separate WC with wash basin (Note: Paper towel holder!) to be arranged for the exclusive use of galley and catering staff. In ships above 1.600 GRT without separate cabins and private or semi-private bathrooms for all engine personnel, a changing room outside the engine space, with easy access to it, to be provided and fitted with clothes lockers, showers and wash basins. Facilities for washing, drying and ironing personal clothes to be provided appropriate to the size of the crew. The minimum headroom in all crew accommodation where full and free movement is required should not be less than 1980 mm as required by IMO, but as today’s (year 2002) standard door height is 2000 mm, a free height of not less than 2100 mm should be specified. Each cabin should as a minimum have a writing facility and one extra seating, one chest of drawers and a wardrobe. It is also considered sound practise to place the bed in longitudinal direction and to have a sofa placed at 90º to the bed as alternative sleeping place for use in adverse weather. Considering these items, a suggestion for a reasonable minimum space allocation for cabins including bathroom, would be the following: * Rating’s cabin w/shared bathroom : ~ 9,5 m2 * Rating’s cabin w/separate bathroom : ~ 11 m2 * Junior officer’s cabin w/sep. bathroom : ~ 16,5 m2 * Senior officer’s cabin w/sep. dayroom and bathroom : ~ 17 - 20 m2 Examples of cabin layouts according to the above are given in Figs. 152.10 A, B, C and D at the end of Gp 15. It should be added, however, that GA-plans, arrangement and size of cabins and public rooms, colour schemes, interior details and architectural solutions are difficult to generalise.

Generally one may state and realise that there are as many good and practical solutions as there are owners and ship/accommodation designers. 153 VIBRATIONS 153.0 General Guidelines The most important excitation sources causing vibrations are the propeller plus free forces and moments generated by main and auxiliary machinery. The propeller forces may be calculated based on wake measurements in a model tank. The underwater hull form above the propeller as well as propeller clearances must also be considered. For details see MGp 2/Gp 21. Vibration frequencies in the higher range may cause damage to instruments and equipment, particularly high up in the superstructure, e.g. on the bridge. High frequencies may cause cracks in the steel structure. However, also lower frequencies may be unacceptable and even harmful to the people on board, hence vibrations are a determining factor for dimensioning and structuring the superstructure. In this regard the main purpose is to avoid resonance areas, i.e. when the natural frequency of the superstructure/elements coincides with imposed vibration frequencies. Generally, it is only the lowest natural frequency of the superstructure that may be in resonance with the excitation forces, this should therefore be somewhat higher than the highest excitation frequency at max. rpm. Consequently, the superstructure is to be designed to achieve the highest possible natural frequency, i.e. with max. margin for resonance. Hence the deck house should as previously mentioned, not be higher than strictly necessary as determined by required view from the bridge and space requirements. Further the outer bulkheads as well as inner structural bulkheads should have a stiffest possible support by continuous bulkheads or pillars underneath. Large deck openings should be compensated for by added structural strength. For further details see MGp 2/Gp 25. Max. permissible vibrations, e.g. by reference to a curve combining frequency and amplitude, should be clearly stated in newbuilding specifications. Prior to and during construction of the accommodation area, it is important to try to “foresee” where unpleasant vibrations may occur in cabins as well as in public and operational areas. It may be a wise precaution to specify a “finite element” calculation for vibration analysis of hull and deck houses. In addition to proper stiffening and support of the steel structure, it is important that machinery and equipment in galley, provision rooms, etc. are properly secured and braced and mounted on vibration dampers. DNVs “Guidance for prevention of harmful vibrations in ships” should be followed, with maximum values not to exceed 10 mm/sec, according to ISO guidelines for vertical and horizontal vibrations in ships. One should also bear in mind that low frequency vibrations may increase the tendency of seasickness. (ABS’ “CrewHab”, see 151.10, also gives useful criteria on vibrations).

154 NOISE 154.0 General Guidelines General recommendations for noise levels in the accommodation, engine room etc. have been given by Class and maritime authorities, ref. DNVs Comfort Class and NMD regulations (Sect. 25). These should be taken into account when preparing specifications. Noise measurement of doors should be carried out in accordance with ISO 140/3. Permitted noise level is defined by ISO's N-curves (“Noise rating curves”), where the decibel (dB) values are given as a function of the “octave band frequency”. The db(N)-values are values at 1000 Hz octave band frequency, whereas the dB(A) values are given at 500 Hz. The latter is normally applied when stating permissible/recommended values. Crew members exposed to noise above 90 db(A) (=N85) are requested to use ear protection. Entrance to such areas to be marked “High Noise Level - Use Ear Protection”. If the noise level is above 120 dB(A) (=N115), the text to read : “Caution - Excessive High Noise Level - Use of Ear Protection is mandatory - Short Inspections only”). Examples of maximum recommended db(A) noise levels are (See also ABS’ “CrewHab”): * Bedrooms : 60 * Mess/lounge(s) : 60 * Wheelhouse : 65 * Working spaces : 65 * Control room : 75 * Eng. workshop : 85 * Engine room : 90 - 110 (Manned - periodically unmanned respectively) 155 MATERIAL REQUIREMENTS 155.0 General Guidelines Maritime authorities and Class have specific requirements to materials used in accommodation. These requirements apply to fire precautions, noise, heat transfer and toxicity. For details, see also MGp5/Gps 51-53. 156 HYGIENE AND CLEANING 156.0 General Guidelines When planning the accommodation, various details, which will facilitate future cleaning, should be taken into account: * Straight alleyways with minimum amount of recesses/protrusions. * Smooth surfaces, implying that piping, cables etc. are arranged inside walls/bulkheads.


9

* Wall-mounted water-closet stools. * Fixed furniture fastened to floor to have recessed and closed bases. * Cupboards/lockers either to extend all the way to the ceiling (dust-tight) or to have

easily accessible, open (storage) space on top. * All materials to be of “easy to clean”-type, particularly in shower/toilet rooms. * To prevent dirt spreading in the accommodation, changing rooms to be arranged in

direct connection to engine room and working areas, including location for changing shoes, e.g. at engine room entrance. Dirt absorbing mats at all entrances.

* Galley floor to be well drained for easy hosing/flushing. * Cleaning lockers with utility sink and equipment on each deck. * Central vacuum cleaning system For further details see MGp 4/Gp 44/SGp 444. If the vessel shall trade permanently in US waters, one may want the galley to be approved by an USPH inspector. If so, contact with the USPH office should be made at an early stage. Since the regulations do not give accurate descriptions of recommended/required technical solutions, the evaluation by the individual inspector (from case to case), will be of vital importance. (For passenger vessels trading on the US such approval is mandatory!). 157 CONSTRUCTION SYSTEMS / ELEMENTS 157.0 General Guidelines The deck house should be constructed with continuous steel bulkheads in line with the principal structural elements of the hull (See also 153.0 and MGp 2/Gp 25). Larger spans of internal girder/beam systems improve the flexibility as to cabin arrangements, modules etc. However, this may increase construction cost and danger of vibrations. Some yards prefer to use vertical corrugations for stiffening of the outside walls of the deck house. This makes the steelwork cheaper and facilitates installation of inside lining and insulation, but may have disadvantages such as more difficult outside maintenance, increased wind resistance and a less aesthetic appearance. There should be no camber or spring in the accommodation decks. 157.1 Modules 157.10 General Any prefabricated module systems should be approved prior to contract signing. Such modules will usually comprise cabins and/or adjoining bathrooms, while offices, mess rooms etc. are erected on site. A cabin prototype (“mock-up”) will in such case be advantageous for early inspection and modifications prior to final fitting on board.


10

Prefabricated modules may be cost effective if many cabins of same type. Prefabricated cabins may, however, lead to a non-optimised use of the area on board, and thereby fewer cabins. 157.2 Drawings 157.20 General Accommodation drawings of scale 1:50 for Owner’s approval should be requested from the yard at an early stage. Drawings must show the main supporting steel structure, pipe and ventilation ducts and other important elements and systems, also including arrangement of furniture, lights and other fittings. The yard further to present 1:20 (1:25) drawings with sections and elevations including ceiling plans for all types of cabins and toilet rooms, public rooms, wheelhouse, galley and special rooms such as cargo control room, offices, conference room, etc. The drawings to show location of furniture, instruments and equipment, electrical switches, sockets, lighting fixtures etc., furthermore detailed drawings of wall-, ceiling- and floor systems, including window- and door details. For further details concerning drawings and drawing approval, see Part I/Ch. 6 of the Manual. 157.3 Colour Schemes 157.30 General The Owner should have the final decision as to selection of colours, panelling surfaces, deck top covering, upholstery, furniture, curtains, etc. Proposals and samples should normally be presented by the yard. Specifying different panel colours deck-wise on corridor walls, doors etc. is inexpensive (within certain limits) and may be helpful for easy orientation and may offer variation in an otherwise monotonous and dull accommodation. Properties that should be considered include: * “Timelessness” of colours * No fading due to exposure to sunlight 157.4 Stairs 157.40 General Internal main stairs should (if at all possible) be arranged in longitudinal direction. For details see MGp 5/Gp 52/SGp 524.


11

158 GENERAL CONSIDERATIONS CONCERNING THE ACCOMMODATION AREA 158.0 General Guidelines It is considered outside the scope of this Manual to discuss the social systems on board, since these may differ from company to company. (However, some considerations concerning manning are given in Part I/Ch. 2 of the Manual). Nevertheless, it is reasonable to conclude that everybody on board is in need of varying degrees of social relationships, further that the previously common and complete separation of officers and crew during off-duty hours may not always be considered desirable or necessary any more, especially with today’s limited crew sizes. 158.1 Cabins and Corridors 158.10 General (See also SGp 152) When specifying furniture and equipment, it might prove sensible to base this on following categories of cabins: * Senior officers * Officers * Crew * Riding crew/travelling squads * Suez crew (if applicable) Only floor space, internal room arrangement and type/number of furniture should generally differ for the various categories and not the quality, which should be maintained throughout, with exception of a possible Suez crew’s cabin, which is to be kept absolutely simple and with only steel furniture. (Examples of crew and officers’ cabins are given in the sketches at the end of Gp 15). See also MGp 5/Gp 54. Corridors form parts of escape routes and should be dimensioned accordingly. For cargo ships there are no definite rules, but an absolute minimum width should be 750 mm between handrails, also allowing transportation of a patient on a standard stretcher, around corners and through doors. On larger vessels, 1000 mm may be a recommended figure. 158.2 Central Lobby 158.20 General The arrangements of a central lobby, gathering and concentrating the traffic from main staircases, deck and engine room, will create a junction where everybody have to pass. If the lobby furthermore is designed and furnished with easy-to-clean, preferably wooden, non- upholstered furniture, with the purpose of giving a pleasant atmosphere where members of the


12

crew can sit down during coffee breaks etc., one may have created an area for good social contact. Offices and the night/duty mess should also be located (on the same deck) in the vicinity of the central lobby, if possible. 158.3 Lounge(s)/Day Room(s) 158.30 General The lounge should have a central location, preferably not too far from mess room and lobby, and in the vicinity of possible other leisure areas such as swimming pool. The lounge should have small tables and loose chairs, which could be easily regrouped e.g. for watching TV. The ship’s library should preferably be located to the vessel’s day room and arranged in open shelves with stoppers. Equipped with carpet tiles (easy to replace), attractive colours, large windows, (green plants/flowers) and pleasant lighting, the lounge will hopefully become a leisure area frequently used by everybody on board. If the modern “unit crew” concept is adapted by the Owner, i.e. only one mess room and one lounge for officers and ratings together, it might be practical to arrange these areas for a later possible partitioning in case of vessel’s sale or implementation of regulations concerning smoking/non smoking areas. Arrangement for installation of at least one PC for the crew’s use, e.g. for Internet, e-mail etc. should be considered. For details, see MGp 8/Gp 85/SGp 855. 158.4 Cafeteria/Mess Room 158.40 General The mess room should naturally be located in the border area between work and leisure, with a direct connection to the galley. Small tables are preferable and the furniture should be of good standard. The mess room should further have pleasant lighting, green plants, large windows etc. A smaller duty- or night mess should be provided for meals during intensive work periods, e.g. drawing pistons, etc. To keep the size within reasonable limits, it might be better to consider a second serving in case of guests, rather than building the mess room for surplus capacity (See SGp 152). 158.5 Recreation Facilities 158.50 General On larger vessels a gymnasium may be relevant, preferably in direct communication with the main recreation area and swimming pool, if fitted. Normal outfit would be lockers, wooden wall bars and various exercise equipment supplied by Owner. Such equipment should be


13

fitted by the yard. If space permits, the room could extend through two decks to permit ball games. In such case the lighting fixtures must be high on the walls (and not in the ceiling) to facilitate access. As a minimum, recreation rooms should accommodate a table tennis set-up. Swimming pools must be arranged longitudinally, if installed. A good size would be 10 x 4 m, which will allow for normal swimming. The sea water is to be re-circulated through a filter unit. A direct dumping line to be provided. 158.6 Wheelhouse with Radio Equipment 158.60 General In addition to normal navigation and communication equipment (see MGp 4/Gps 41/42) following outfit should be considered: * Refrigerator and coffee/tea boiler, small sink w/hot and cold water * Full length “Pullman” type sofa with draw-curtains, to serve as “captain’s sea cabin”

(Ref. IMO A.708 (17)). * Chart room or navigating table with draw-curtains * A toilet with wash basin, adjacent to the bridge * A drinking water fountain Radio equipment (GMDSS) (see MGp 4/Gp 42) is normally incorporated in the wheelhouse. The radio equipment supplier often plans the layout, but working conditions, light, etc. should anyhow be carefully considered in order not to interfere with navigation and night vision. (As the ship-to-shore and v/v communication now (2002) is via satellite mail systems and satellite phone for all newer vessels, the radio room has become obsolete on normal cargo ships). There should also be a satellite phone extension on the bridge to ensure that all incoming calls are received. Fire alarm and navigation light panels to be located aft of and separately from all manoeuvring- and ship handling equipment, navigating instruments and alarms. If the bridge has “around-the-horizon” windows, separate consoles for such lights should be arranged. A special switch should be arranged on the entrance door to the bridge cutting off the corridor light outside and giving a red “night light” instead. Such red lights (with dimmer) should also be arranged in the ceiling above the navigating instrument panels. 158.7 Offices, Conference Room, Files 158.70 General An office area located near the central lobby on the first accommodation deck, will greatly improve communication and cooperation on board and with visiting persons. The vessel’s trading may influence the layout; open or cell-based solutions should be evaluated. Depending on vessel’s type and trade, the deck office may contain control equipment such as remote control panel for ballast pumps and valves (since ballast control is the responsibility of


14

the Chief Officer and not of the engineers), reefer container control panel etc. It may be combined or connected with the Chief Officer’s office. Desks for other officers may also be relevant. The conference room should be closely connected with the office area, but not just as a part of the Master’s office. It is far more useful during port clearances and for meetings if built as a separate room. A general file should be located in the office area, preferably in the conference room. This file should be based on the Owner’s system code and contain all ship drawings and instruction books. Each senior officer’s desk plus the conference room should also have a PC with screen and keyboard, connected to a common server system. A data projector connected to the conference room PC, should be considered. 158.8 Changing Room(s) 158.80 General Changing room(s) to have easy access to engine room and deck, common for officers and crew. If a location covering both deck and engine room is difficult, two changing rooms must be arranged. A high standard of the accommodation in general (carpet tiles, textiles on chairs, etc.) is waste of money if the changing rooms are not adequately located and equipped (e.g. shower, wash basins, one locker for each person and possibly washing machine/dryer for work clothes). See also SGp 156 and MGp 4/Gp 44/SGp 444. 158.9 Hospital 158.90 General A well equipped first aid room with medicine locker should normally be arranged in direct connection with the hospital, the latter having one or more beds, adjoining toilet and a bath tub for cooling of severe fire burns, see also MGp 5/Gp 58/SGp 583. (One bed only may be permitted, provided all crewmembers have single cabins with separate bathrooms). The hospital should be located away from noise and arranged to allow for a stretcher to be carried into the room. Easy access from open deck is also important (see ILO convention 92, Art. 14). For further details, see MGp5/Gp 50/SGp 504.

159 MISC. ACCOMMODATION DETAILS 159.0 General Guidelines Specification and drawings should be thoroughly studied. For details and equipment not shown on drawings, practical locations and “user friendly” fittings to be agreed with yard. This may include: * Knobs and mountings * Book shelves, pictures, fixed ashtrays, paper bins etc. * Toilet paper holders, handgrips etc. in toilet/shower rooms * Plug sockets, small lamps, light switches etc. Check that doors (also for lockers etc.) and drawers can be fully opened and not obstructed by other accommodation details. Protruding fittings, such as doorstoppers, knobs, etc. to be located and fitted in a manner not causing obstructions to people passing. Also check that doors will not collide and that they are hinged in such a way that “walking around the door” to get out is avoided. Doors in public rooms are to open outwards, cabin doors generally inwards. Check that one’s hand is not pinched when opening/closing of doors and drawers. Protruding objects not to be placed where people may bend, e.g. to pick up/put on shoes, etc. Mirrors should be placed in such a way that a window or a strong light source is not reflected. A notice/pin board should be placed in all cabins, offices, mess/day rooms, control rooms etc. for messages, notes, personal photos etc. to avoid tape or glue on the walls. 159.1 Information System and Signs 159.10 General Safety on board is greatly facilitated when the crew as well as passengers and visitors easily can find their way through the accommodation. In addition to a logical and practical layout, this will also require an effective information system. This will reduce possible misunderstandings and also serve to direct visitors. A well planned information system with signboards to guide the traffic on deck and inside the accommodation should be arranged in close cooperation yard-Owner. The signboards should have large, easily readable letters, with a main information signboard in a central lobby or in the office area, also with boards on each deck. Escape routes and exits to be marked with fluorescent signs (ref. NMD Sect. 18, §10,2.4). 159.2 Lighting in Accommodation 159.20 General (For details, see MGp 8/Gp 89/SGp 892).

The current NMD-rules (year 2002) require an average light intensity of 150 lux in cabins and public rooms, but dispensations have been given down to 100 lux. (Even this may be rather high for comfort since the average value in living rooms in homes is around 50 lux.) It is, however, very important that the light conditions are adjusted to the relevant work- or rest situation, and that the light sources are not glaring. An unshielded light source giving direct eye contact (e.g. in corridors leading to the wheelhouse) will destroy a person’s night-sight for several minutes, which could prove disastrous in a critical situation. It is recommended to locate the corridor lighting fixtures in the corner between wall and ceiling with a vertical shielding or countersunk in the ceiling with grids. Exceptions are emergency lighting, which should be located close to the floor (smoke). A master (“cut-all”) light switch should be installed just inside the entrance of each cabin and public/common room to save electricity. 159.3 Drainage of Outer Bulkheads 159.30 General If insulation has been fixed directly to steel bulkheads from deck to deck, gutter and drainage might not be absolutely necessary, but are generally recommended. If the insulation material is mounted on the bulkhead lining or if parts of the outer bulkhead are not completely insulated, a gutter must be arranged, with cut-outs in the bulkhead stiffeners giving free flow of condensed water to drain pipes. Insulation close to gutter must be fixed/covered in a way preventing insulation material from falling down and clogging the drains. For details, see MGp 5/Gp 51. Check that all gutters are fully welded, cleaned and well protected against corrosion prior to fitting the panelling. Also access hatches to be arranged for cleaning of drains. These hatches must be marked on the panelling and on drawings. Self-closing devices should be arranged in the lowermost drain pipes to prevent external water from entering the accommodation. 159.4 Location of Drains – General 159.40 General Normal trim conditions to be taken into account when arranging drains. In larger wet rooms, drains forward and aft on both sides should be considered. 159.5 Smoking Areas/fixed Ashtrays 159.50 General Ashtrays (preferably fixed/wall mounted) should normally only be installed in designated smoking areas. Cigarette supports should be 50 mm long so that lighted cigarettes will

extinguish by themselves if left in the tray, and not drop burning onto materials that may ignite or be scorched. 159.6 Owner’s Delivery 159.60 General The follow-up of equipment and parts supplied for newbuildings by the Owner may prove to become a time consuming task for the responsible Supt. (See also Part I/Ch. 6 - “Newbuilding Procedures” and MGp 4/Gp 44/SGp 440). Such equipment is normally ordered by Owner’s purchase department, which also arranges forwarding to the yard. Some equipment may be purchased locally by the Supt. or by the vessel. It is very important that the person handling the purchases specifies and ensures safe packaging and mode of transportation, taking into account type of commodity and transport conditions. The yard should agree to receive and store all equipment in safe and climatically satisfactory storage until bringing it on board. Relevant drawings should be requested from the supplier for equipment fitted/installed by the yard. For other equipment, the responsible department heads on board should in due course plan when, where and how equipment and parts are to be installed in an optimum manner. If this is done in a hurry and without planning, it will prove difficult and time consuming to store the equipment efficiently and to find it when it is going to be used. Advanced planning and ordering of steel cabinets etc. for storing of all spare parts are very important to ensure good order and overview. Storage and marking to be in accordance with Owner's code system and maker’s part numbers. A reasonable progress plan for Owner’s Delivery may be: * Specification of Owner’s deliveries to be checked and commented on by the Supt. * Effecting orders. * Information to Supt. regarding transport details. * Shipping documentation to Supt. * Equipment received at yard and inspected by Supt./ship officers. Possible damage

reports to supplier and/or Owner’s office. * Time schedules and plans for location on board to be worked out by Supt./SMT. * Items are brought on board, and checked against plans and specifications. * Proper marking of lockers, cabinets, shelves etc. Establish a computerised storage file or

similar to give easy identification and location of all items on board. _________
