PART 28_REQUIREMENTS FOR COMMERCIAL FISHING INDUSTRY VESSELS
--Table of Contents
 
 Subpart C_Requirements for Documented Vessels That Operate Beyond the 
 Boundary Lines or With More Than 16 Individuals On Board, or for Fish 
              Tender Vessels Engaged in the Aleutian Trade
 
Sec. 28.255  Bilge pumps, bilge piping, and dewatering systems.

    (a) Each vessel must be equipped with a bilge pump and bilge piping 
capable of draining any watertight compartment, other than tanks and 
small buoyancy compartments, under all service conditions. Large spaces, 
such as enginerooms must be fitted with more than one suction line.
    (b) In addition to the requirements of paragraph (a) of this 
section, a space used in the sorting or processing of fish in which 
water is used must be fitted with dewatering system capable of 
dewatering the space under normal conditions of list and trim at the 
same rate as water is introduced. Pumps used as part of the processing 
of fish do not count for meeting this requirement. The dewatering system 
must be interlocked with the pump(s) supplying water to the space, so 
that in the event of failure of the dewatering system, the water supply 
is inactivated.
    (c) Except as provided by paragraph (f) of this section, each vessel 
79 feet (24 meters) or more in length must be equipped with a fixed, 
self-priming, powered, bilge pump connected to a bilge manifold.
    (d) If a bilge pump required by paragraph (a) of this section is 
portable, it must be provided with a suitable suction hose of adequate 
length to reach the bilges of each watertight compartment it must serve 
and with a discharge hose of adequate length to ensure overboard 
discharge. A portable pump must be capable of dewatering each space it 
serves at a rate of at least 2 inches (51 millimeters) of water depth 
per minute.
    (e) Except for a fire pump required by Sec. 28.315, a bilge pump 
may be used for other purposes.
    (f) Except where an individual pump is provided for a separate space 
or for a portable pump, each individual bilge suction line must be led 
to a manifold. Each bilge suction line must be provided with a stop 
valve at the manifold and a check valve at some accessible point in the 
bilge line to prevent unintended flooding of a space.
    (g) Each bilge suction line and dewatering system suction must be 
fitted with a suitable strainer to prevent clogging of the suction line. 
Strainers must have an open area of not less than three times the open 
area of the suction line.
    (h) Each vessel must comply with the oil pollution prevention 
requirements of 33 CFR parts 151 and 155.
