Inland Waters Small Passenger Boat Code 7 MACHINERY 7.1 General 7.1.1 Machinery, fuel tanks and associated piping systems and fittings should be fit for purpose and be of a design and construction adequate for the service for which they are intended. Moving parts, hot surfaces and other hazards should be installed and protected so as to minimise danger to persons during normal movement about the vessel. Materials should be fire resistant or otherwise protected from fire. Plastic fittings at the Hull are not recommended. 7.1.2 A vessel should be provided with a fuel tank of sufficient capacity for the main engines, and its area of operation. All fuel tanks vents should be fitted with a flame gauze as required by BS/EN/ISO 10088, and carried to at or above tank filling plate level and where there should be no danger from escaping fuel or vapour. 7.1.3 Where the machinery is in its own dedicated compartment and remote from the operator, means should be provided to isolate a source of fuel, which may feed a fire. A valve or cock, which can be shut from a position outside the engine space should be fitted in the fuel-feed pipe, as close to the fuel tank as possible. Where the machinery is situated directly below the operator, and within easy reach for control and isolation in event of emergency, these conditions need not apply. Petrol tanks for outboards motors should have quick connection shut off devices. 7.1.4 Measures should be taken to prevent spillage and build up of flammable vapours in any part of the vessel, including bilges during fueling. 7.1.5 Vessels should have an efficient and reliable starting mechanism. Where the means of starting is by battery, charging facilities for the battery should be available. 7.1.6 In CATEGORY C and D WATERS: where the sole means of starting is by battery, there should be a duplicate battery connected to the starter motor by a “change over switch” so that either battery or other means of obtaining power can be used to start the engine. 7.1.7 All inflatable boats, boats fitted with buoyant collar, and open boats that achieve planing speed, when fitted with remote throttle controls, should be fitted with a kill cord, to be used at all times during navigation. 7.6 Electrically powered engines 7.6.1 An electrically powered propulsion engine may be used provided that: 1. the installation complies with the provisions of Section 8 of this Code in so far as they are applicable, and to The Institution of Electrical Engineers (IEE) Regulations for the electrical and electronic equipment of ships as is appropriate to the size of the installation. 2. the arrangement of batteries, including in particular their stowage and adequate ventilation, should comply with the IEE regulations – Section 15. 3. a manually operated master switch, which can be operated from the steering position, should be fitted. It should be capable of cutting off the electrical supply to the propulsion motor. 4. the connection from the battery charger on board the vessel to the charging point ashore should be by means of a 3-core flexible cable of adequate current carrying capacity, suitably constructed and graded, complying with the slash-proof category of BS/EN/ 6030-2, IEC60309-2, Plugs, socket outlets and couplers for industrial purposes - Dimensional interchangeability requirements for pin and contact tube accessories. The battery charging panel of the vessel should be adequately ventilated and have a positive switch and an indication light to show when charging of the vessel’s batteries is taking place. 5. the battery charging arrangement should incorporate control of the battery compartment exhaust ventilation fan, if fitted, so that the fan is automatically switched ON when battery charging commences and continues for one hour after charging is completed. 6. the motor and controller compartments should be adequately ventilated. 7.6.2 Small electrically powered outboards may be used in the event of an emergency N.B.
