berthing only submarines or MSO ships may use 3-inch lateral.
Space lateral and pier riser at 150 feet (46 m). This
relatively close spacing facilitates flexible berthing
configurations. Mission change frequently and flexibility
should be incorporated. Hose riser assemblies need not be
provided at the end of piers unless specifically required by the
activity. Use dual hose receivers to provide capability for
nesting ships. Nesting may occur during major exercises and
holidays and during periods when nearby berth are down because
of damage or repair. Provide containment according to Title 33
CFR Part 154.530 (U.S. Coast Guard regulations). See Figure 9
for pier receiving hose riser assembly connection.
Consider the following when laying out a pier
collection pipeline:
a)
Ships of same class type often berth together.
b) Locate a riser at the pier end for use by oil SWOB
or service craft.
c) Install valves at head of each pier to allow for
isolation in case of pier pipeline damage.
d) Allow for minimum slope toward free discharge to
prevent liquid stagnation and freezing.
e) Use a minimum fluid velocity that will prevent
settling of suspended solids and minimize emulsification.
3.8.2.3
Pipe Materials.
Specification of oily waste collection
piping should include:
a)
Minimum operating pressure of 150 psig (1,034 kPa).
b) Use mechanical joint, lined ductile iron for
exposed locations where high impact resistance is important.
Support exposed pipe per manufacturer's recommendations. In
other exposed locations, for superior corrosion resistance,
consider thermoplastic (high density polyethylene) pressure pipe
with butt fusion joints. Plastic piping on pier and wharf
systems should be protected from impact of floating debris and
