This Guide has

When an Owner elects to install such a system in a vessel classed with this Bureau the system is to be of an approved design. Crude-oil burning installations which are fitted in accordance with thi
8、s Guide are considered to be of an approved type. When the design and installation of the system are in accordance with this Guide, a certif- icate will be issued by the Bureau when requested by the Owners or Builders and a notation will be made in the Record. This Guide is based on the recommendati

12、ng system Associated electrical installation and control systems slops 3.0 Crude-Oil Supply Crude oil or slops are to be taken directly from cargo tanks, slop tanks, or suitable tanks fitted in cargo tank area. They are to be separated from non-gas-dangerous areas by means of cofferdams with gas-tig
13、ht bulkheads. The entire system of pumps, strainers, separators, and heaters, if any, is to be located in the cargo pump room or other space considered dangerous. Such spaces are to be separated from the engine and boiler room by gas-tight bulkheads (See 10.0). When the crude oil is heated by steam
14、or hot water the outlet of the heating coils is to be led to a separate observation tank installed with the above mentioned components. This closed tank is to be fitted with a vent pipe led to the atmosphere in a safe location in accordance with the requirements for tankers in the “Rules for Huildin
15、g and Classing Steel Vessels.” This vent outlet is to be fitted with a suitable flameproof gauze of corro- sion-resistant material which is to be easily removable for,kleaning. b , A + 4.0 Fuel-oil Burning Arrangements are to be provided in all cases for burning fuel oil as well as crude oil and slo
16、ps. These arrangements are to comply with the “Rules for Huilding and Classing Steel Vessels.” The fuel-oil supply to and the returns from biirriers are to be equipped with a suitable mechanical interlocking device that precludes the simultaneous hiirning of fuel oil and crude oil.

When boilers are fitted with a double casing, particular care is to be taken to preclude the possibility of gases leaking into and being trapped between the casings or accumulating in pockets in the inne

Means are to be provided so that the boiler can be purged automatically before firing. 6.0 Vent Hood Boilers are to be fitted with a suitable hood constructed in such a way as to enclose burners, valves, and oil pipes as much as possible without preventing or restricting the flow of air in
20、to the burner registers. The hood is to be fitted with suitable doors placed in such a way as to enable inspection of and provide access to oil pipes and valves enclosed within it and is to be connected with a duct exhausting to the open deck in a safe location. This duct is to be fitted with a suit

At least two me- chanically-driven exhaust fans having nonsparking impellers are to be fitted to insure that pressure inside the hood is maintained at a level less than that in the boiler room. These exhaust fans are to be con- nected with an au
