LLOYD'S REGISTER OF BRITISH AND FOREIGN SHIPPING

Rules for the Burning and Carrying of Liquid Fuel

The following rules for steel vessels have been approved :

1. In vessels fitted for burning liquid fuel, the record "Fitted for Liquid Fuel" will be made in the Register Book.

2. The compartments for carrying oil fuel must be strengthened efficiently to withstand the pressure of the oil when only partly filled and in a seaway. They must be tested by a head of water extending to the highest point of the filling pipes or 12 feet above the load line, or 12 feet above the highest point of the compartment, whichever of these is the greater.

3. If peak tanks or other deep tanks are used for carrying liquid fuel, the riveting of these should be as required in the case of vessels carrying in bulk. The strengthening of these compartments must be to the Committee's satisfaction.

4. Each compartment must be fitted with an air-pipe, to be always open, discharging above the upper deck.

5. Efficient means must be provided by wells and sparring or lining to prevent any leakage from any of the oil compartments from coming into contact with cargo or into the ordinary engine-room bilges.

6. If double bottoms under holds are used for carrying liquid fuel, the ceiling must be laid on transverse battens, leaving at least two inches air space between the ceiling and tank top and permitting free drainage from the tank top into the limbers.

7. The pumping arrangements of the oil-fuel compartments and their wells must be absolutely distinct from those of other parts of the vessels and must be submitted for approval.

If it is intended to sometimes carry oil and sometimes water ballast in the various compartments of the double bottom the valves controlling the connexion between these compartments and the ballast donkey pump, and also those controlling the suctions of the special oil pump, must be so arranged that the suctions for each separate compartment cannot be connected at the same time to both pumps.

8. No wood fittings or bearers are to be fitted in the stokehold spaces.

9. Where oil-fuel compartments are at the sides of, or above, or below the boilers, special insulation is to be fitted where necessary to protect them from the heat from the boilers, their smoke boxes, casings, etc.

10. If the fuel is sprayed by steam, means are to be provided to make up for the fresh water used for this purpose.

11. If the oil fuel is heated by a steam coil the condensed water should not be taken directly to the condenser, but should be led into a tank or an open funnel mouth, and thence led to the hot well or feed tank.

12. The above arrangements are applicable only to the case of oil fuel, the flash point of which, as determined by Abel's close test, does not fall below 150° Fahrenheit. NOTE. The foregoing alterations and amendments also apply to the Rules for Iron Vessels. By order of the Committee,
