The Merchant Shipping (Passenger Ship Construction: Ships of Classes I, II and II(A)) Regulations 1998

General

62.—(1) In every ship the machinery, boilers and other pressure vessels, associated piping systems and fittings shall be of a design and construction adequate for the service for which they are intended and shall be so installed and protected as to reduce to a minimum any danger to persons on board, due regard being paid to moving parts, hot surfaces and other hazards. The design shall have regard to the materials used in construction including design standards, material specifications, and certification etc, the purpose for which the equipment is intended, the working conditions to which it will be subjected and the environmental conditions on board.

(2) Where the arrangements of the main propulsion machinery are unconventional and without a known history of satisfactory service the Secretary of State may require a separate source of propulsion power to be provided sufficient to give the ship a navigable speed.

(3) The main and auxiliary machinery essential for the propulsion and overall safety of the ship shall be provided with effective means of control. In addition, suitable means shall be provided to ensure that machinery can be brought into operation from dead ship conditions.

(4) Where risk from over-speeding of machinery would otherwise exist, two independent means of control shall be provided to ensure that the safe speed is not exceeded; provided that where the Secreary of State considers it is safe to do so, a single means of limiting the speed of machinery may be permitted.

(5) All boilers, main or auxiliary machinery or any parts of such machinery, all steam, hydraulic, pneumatic and other systems and their associated fittings which are under internal pressure, shall be subjected to appropriate testing including a pressure test in excess of the working pressure, prior to being put into service for the first time. The pressure test shall have regard to—

(a) the design/standards and materials of which the respective items are constructed;

(b) the purpose for which they are intended to be used; and

(c) the working conditions under which they are intended to be used, and such parts shall be maintained in an efficient condition and be subject to periodic inspection/testing.

(6) Access shall be provided to facilitate the cleaning, maintain cleanliness, inspection and maintenance of main propulsion and auxiliary machinery including boilers and pressure vessels.

Additional requirements for ships constructed on or after 1st September 1984

(7) In every ship means shall be provided whereby the normal operation of propulsion machinery can be sustained or restored when there is a breakdown of—

(a) a generating set which serves as a main source of electrical power;

(b) the sources of steam supply;

(c) the boiler feed water systems;

(d) the fuel oil supply systems for boilers or engines;

(e) the sources of lubricating oil pressure;

(f) the sources of water pressure;

(g) a condensate pump and the arrangements to maintain vacuum in condensers;

(h) the mechanical air supply for boilers;

(i) an air compressor and receiver for starting or control purposes;

(j) the hydraulic, pneumatic or electrical means for control of main propulsion machinery including controllable pitch propellors; or

(k) any other auxiliary system essential for propulsion.

• A partial reduction in propulsion capability from normal operation may be permitted if it can be shown that the safety of the ship will not be impaired.

(8) In any such ship the main propulsion machinery and all auxiliary machinery essential to the propulsion and the safety of the ship shall be designed to operate when the ship is upright and when inclined at any angle of list up to and including 15 degrees either way under static conditions and 22.5 degrees either way under dynamic conditions (rolling) and simultaneously inclined dynamically (pitching) 7.5 degrees by bow or stern. Where it can be shown that the overall safety of the ship will not be impaired, deviation from the aforesaid angles may be permitted, taking into account the type, size and service conditions.
