Large Fishing Vessel Inspection Regulations

13 (1) Air receivers, main engines, reduction and reverse gearing and main shafting shall be constructed and inspected during construction as required by the Marine Machinery Regulations.

(2) Air receivers and other pressure vessels that are subject to inspection and are being inspected for the first time shall be tested by hydraulic pressure as specified in Schedule III after the working pressure has been ascertained in accordance with the Marine Machinery Regulations.

(3) Where main engines depend on compressed air for starting, there shall be sufficient air receiver capacity provided to permit, without replenishment of the air,

• (a) 12 consecutive starts of reversible engines, and

• (b) six consecutive starts of non-reversible engines,

and there shall be provided one air compressor driven by a prime mover that can be started without the use of compressed air.

(4) A safety valve shall be provided on every air receiver or on the piping between each air compressor and each air receiver, but where the safety valve is fitted on the piping, a fusible plug shall be provided on each air receiver.

(5) Exhaust pipes and silencers shall be efficiently water-cooled, lagged or so installed that they will create no fire hazard.

(6) Where exhaust pipes pass through the side of a fishing vessel, the connection shall be watertight and provision shall be made so that the engine cannot be flooded.

(7) An inspector shall satisfy himself by actual examination, and by a series of calculations when required, that

• (a) the working pressure assigned to air receivers and other pressure vessels subject to inspection can be safely carried and is suitable for the piping and machinery;

• (b) the propelling machinery is sufficient in power and capacity to enable the ship to be manoeuvred and handled at sea with a proper degree of safety, having regard to the voyages the ship is to make; and

• (c) the machinery has been installed in a satisfactory manner and is sufficient and suitable for the voyages intended.

(8) Safety valves shall be set, in the presence of an inspector, to blow off at a pressure not in excess of the working pressure assigned.
