10A. Access to spaces in the cargo area of oil tanker
(1) This regulation applies to oil tankers which are post 1994 ships.
(2) Access to cofferdams, ballast tanks, cargo tanks and other spaces in the cargo area shall be direct from the open deck and such as to ensure their complete inspection. Access to double bottom spaces may be through a cargo pump room, pump room, deep cofferdam, pipe tunnel or similar compartments, subject to consideration of ventilation aspects.
(3) For access through horizontal openings, hatches or manholes, the dimensions shall be sufficient to allow a person wearing a self-contained, air-breathing apparatus and protective equipment to ascend or descend any ladder without obstruction and also to provide a clear opening to facilitate the hoisting of an injured person from the bottom of the space. The minimum clear opening should be not less than 600 millimetres by 600 millimetres.
(4) For access through vertical openings, or manholes providing passage through the length and breadth of the space, the minimum clear opening should be not less than 600 millimetres by 800 millimetres at a height of not more than 600 millimetres from the bottom shell plating unless gratings or other footholds are provided.
(5) For oil tankers of less than 5,000 tonnes deadweight, the Certifying Authority may approve smaller access openings in special circumstances if the ability to traverse such openings or to remove an injured person can be proved to its satisfaction.
(L.N. 415 of 1995)

11. Precaution against oil spills
Means shall be provided to isolate oil spills on the upper deck from accommodation and service spaces and shall take into account stern cargo handling facilities where these are provided.

13. Ventilation of pump rooms and other enclosed spaces
(1) Cargo pump rooms and pump rooms having a similar hazard shall be mechanically ventilated and discharges from the exhaust fans shall be led to a safe place on the open deck. The ventilation of these rooms shall have sufficient capacity to minimize the possibility of accumulation of flammable vapours. The number of changes of air shall be at least 20 per hour, based upon the gross volume of the space. The air ducts shall be arranged so that all of the space is effectively ventilated. The ventilation system shall be of the exhaust type.
(2) Ventilation inlets and outlets and other deckhouse and superstructure boundary space openings shall be located clear of the cargo pump room openings. Openings for machinery space ventilation shall be located as far aft as practicable taking into consideration the location of any stern loading and discharging facilities provided.
(3) The cargo spaces and their adjacent enclosed spaces in combination carriers shall be capable of being ventilated by permanently installed or portable fans. A fixed gas detection system shall be provided in cargo pump rooms, pipe ducts and the cofferdams adjacent to slop tanks. Arrangements shall be provided to detect the presence of flammable vapours in all other spaces within the cargo tank area from the open deck or other easily accessible positions.

13A. Seawater ballast tank corrosion prevention system
(1) This regulation applies to oil tankers and bulk carriers constructed on or after 1 July 1998.
(2) All dedicated seawater ballast tanks shall have an efficient corrosion prevention system, such as hard protective coatings or equivalent. The coatings should preferably be of a light colour. The scheme for the selection, application and maintenance of the system shall be approved by the Director, based on the guidelines adopted by the International Maritime Organization. Where appropriate, sacrificial anodes shall also be used.

15. Machinery
(1) In every ship to which these regulations apply the propulsion machinery systems shall be designed, constructed and installed so that undue stress due to vibration is not induced during normal operation.
(2) All gearing and every shaft and coupling used for transmission of power essential for the propulsion and safety of the ship or for the safety of persons on board shall be so designed and constructed that they will withstand the maximum working stresses to which they will be subjected to in all service conditions taking into account the type of engines by which they are driven or of which they form part.
(3) Every internal combustion engine having a cylinder diameter of 200 millimetres or greater or a crankcase volume of 0.6 cubic metres or greater shall be provided with crankcase explosion relief valves of a suitable type having sufficient area to relieve abnormal pressure in the crankcase. The explosion relief valves shall be arranged or provided with means to ensure that any discharge from them is so directed as to minimize the possibility of injury to personnel.
(4) Every main propulsion turbine and, where applicable, main internal combustion propulsion machinery and auxiliary machinery shall be provided with automatic shut-off arrangements that will operate in the case of failures, such as a lubricating oil supply failure, which could lead rapidly to complete breakdown, serious damage or explosion. The Certifying Authority may permit arrangements that over-ride the automatic shut-off devices.

16. Means of manoeuvring and going astern
(1) Every ship shall have sufficient power for going astern to secure proper control of the ship in all normal circumstances. The ability of the machinery to reverse the direction of thrust of the propeller in sufficient time, and so to bring the ship to rest from maximum ahead service speed shall be demonstrated and recorded.
(2) The effectiveness of any supplementary means of stopping or manoeuvring the ship shall be demonstrated and recorded.
(3) Every ship with multiple propellers shall undergo trials to determine the ability of the ship to manoeuvre with one propeller inoperative.
(4) The trial records including the records required by subregulations (1), (2) and (3) shall be available on the ship.

17. Boilers and other pressure vessels
(1) In every ship every boiler or other pressure vessel and its respective mountings shall, before being put into service for the first time, be subjected to a hydraulic test to a pressure suitably in excess of the working pressure which will ensure that the boiler or other pressure vessel and its mountings are adequate in strength and design for the service for which it is intended and having regard to—
(a) the design and the material of which it is constructed,
(b) the purpose for which it is intended to be used, and
(c) the working conditions under which it is intended to be used;
and every such boiler or other pressure vessel and its respective mountings shall be maintained in an efficient condition.
(2) Means shall be provided which will prevent overpressure in any part of boilers and other pressure vessels, and in particular every boiler and every unfired steam generator shall be provided with not less than two safety valves. The Director may, having regard to the output or any other feature of any boiler or unfired steam generator, permit only one safety valve to be fitted if he is satisfied that adequate protection against overpressure is provided.
(3) Every unattended oil fired boiler shall be provided with arrangements to shut off the fuel supply and give an alarm at an attended location in the event of low boiler water level, combustion air supply failure or flame failure.
(4) Every boiler designed to contain water at a specific level shall be provided with at least two means for indicating the water level, at least one of which shall be a direct reading gauge glass.
(5) Every water tube boiler serving turbine machinery shall be fitted with a higher water level alarm.
(6) Means shall be provided to test and control the quality of the water in boilers.
