9.1 Internal Combustion Engines
9.1.1 Every new ship should be fitted with a marine diesel engine and a sufficient supply of fuel capable of propelling it in a calm sea at a speed of minimum 6 knots for a period of at least 24 hours. Ships in which engines using other fuels are installed should be subject to special consideration of the Board in respect of fire safety provisions.
9.1.2 All engine seatings and securing arrangements, and their ship supporting structure should take into consideration the loadings arising from an acceleration of 2 g in any direction up to angles of heel of 60 degrees.
9.1.3 The design of any engine, and the installation arrangement in the ship should permit unrestricted operation at angles of heel up to 15 degrees. All machinery should be designed to operate when the ship is upright and when listing at any angle up to and including 15 degrees either way under static conditions and 22.5 degrees either way under rolling conditions and simultaneously inclined 7.5 degrees by the bow or stern under pitching conditions
9.1.4 Installation of engines should permit full and ready access to all replenishment points, system connections valves, and filters.
9.1.5 All fluid system connections to engines should be provided with cocks or valves on the hull side, to permit removal of the engine.
9.1.6 Space beneath the engine should be arranged so as to contain any leakage of fluid, and to provide adequate access for removal of such fluid accumulation.
9.1.7 Installation of engines should ensure unrestricted supply of cooling fluids and combustion air in accordance with the engine manufacturer's recommendations.
9.1.8 Combustion and cooling air should be ducted from the weather deck, such ducts being arranged so as to minimize the ingestion of spray or moisture.
9.1.9 Ventilation and cooling airflow should be provided by separate ducts, with equal cross-section area provided for intake and exhaust. Where combustion air is drawn from within the machinery space, the intake duct cross-section area should be proportionally increased.
9.1.10 All ventilation and combustion air ducting should be adequately supported and so far as practical should not pass through any accommodation space.
9.1.11 The cross sectional area of inlet ducts and of exhaust ducts providing ventilation/cooling air only should be at least 22 sq.cm. for each metre of ship beam .
9.1.12 Each engine should be provided with a means of speed control and stopping. Instrumentation should be provided at the position from which the engine is normally controlled, monitoring such parametres and marked with any manufacturer's limitations as recommended by the engine manufacturers. Visual and audio warnings should be provided in the event that fault conditions leading to engine failure develop.
9.1.13 Engines which are normally monitored and controlled from a remote station should be provided with local means of control and monitoring.
9.1.14 Moving parts, hot surfaces and other hazards should be so installed and protected as to minimise any danger to persons on board.
9.1.15 Exhaust pipe runs should be as short as practical and any penetration of partitions or of the ship hull should be adequately insulated. No dry exhaust pipes should be run through spaces normally used for accommodation.
9.1.16 No dry exhaust pipe should terminate within 1 metre of the weather deck, a ventilation intake or a survival craft.
9.1.17 Provision should be made for two-way communication between spaces containing propulsion engines and the station from which the ship is normally steered except if considered impractical by the attending surveyor.
9.1.18 All permanently installed engines should be capable of being started from a "dead ship" condition while alongside.
9.1.19 Engines used for ship propulsion should be installed in enclosed spaces, which should to the maximum extent practical be watertight and any bulkhead common with an accommodation space should be fire resistant and vapour-proof.(see 12.4.8)
9.1.20 Any electrical equipment installed in an enclosed machinery space should be of a certified safe or intrinsically safe type for use in the dangerous environment to which the equipment may be exposed.
9.2 Transmission and Shafting
9.2.1 Engine power for propulsion should be transmitted through transmission and shafting designed and installed in compliance with TC accepted classification society rules or should be of a design with a record of at least 5 years safe operation in similar installation.
9.2.2 Transmissions should provide for ahead and astern propulsion including neutral mode.
9.2.3 Transmission control should be adjacent to controls for the connected engine.
9.2.4 No shafting should penetrate accommodation spaces.
9.2.5 Shafting should be designed and installed so as to ensure that first order critical (whirling) speed is not less than 110% of the maximum designed operating speed.
9.2.6 Shaft penetrations of the hull should be by way of stern glands and bearings in accordance with established practice and provided with the appropriate adjustment or system for lubrication.
