Sec. 58.01-55  Tanks for flammable and combustible oil.

    (a) For the purposes of this section, a machinery space of category 
A is a space that contains any of the following:
    (1) Internal-combustion machinery used for main propulsion.
    (2) Internal-combustion machinery used for other than main 
propulsion, whose power output is equal to or greater than 500 HP (375 
kw).
    (3) Any oil-fired boiler.

[[Page 256]]

    (4) Any equipment used to prepare fuel oil for delivery to an oil-
fired boiler, or equipment used to prepare heated oil for delivery to an 
internal-combustion engine, including any oil-pressure pumps, filters, 
and heaters dealing with oil pressures above 26 psi.
    (b) As far as practicable, each fuel-oil tank must be part of the 
vessel's structure and be located outside a machinery space of category 
A.
    (c) If a fuel-oil tank, other than a double-bottom tank, must be 
located adjacent to or within a machinery space of category A--
    (1) At least one of its vertical sides must be contiguous to the 
boundary of the machinery space;
    (2) The tank must have a common boundary with the double-bottom 
tanks; and
    (3) The area of the tank boundary common with the machinery spaces 
must be kept as small as practicable.
    (d) If a fuel-oil tank must be located within a machinery space of 
category A, it must not contain fuel oil with a flashpoint of less than 
60 [deg]C (140 [deg]F).
    (e) In general, no freestanding fuel-oil tank is permitted in any 
machinery space of Category A on a passenger vessel. A freestanding 
fuel-oil tank is permitted in other spaces only if authorized by the 
Commanding Officer, Marine Safety Center. If so authorized, each 
freestanding fuel-oil tank must--
    (i) Comply with Subpart 58.50 of this subchapter; and
    (ii) Be placed in an oil-tight spill tray with a drain pipe leading 
to a spill-oil tank.
    (f) No fuel-oil tank may be located where spillage or leakage from 
it can constitute a hazard by falling on heated surfaces. The design 
must also prevent any oil that may escape under pressure from any pump, 
filter, or heater from coming into contact with heated surfaces.
