Install mooring bitts, as required. (WP 0017 00)
9.
Maneuver and assemble trident pierhead/extension and causeway, with beach/sea end toward the shore line,
together end to end using warping tugs, ropes/line, flush turn tubes and lift lugs so the tapered surfaces of male
and female shear connectors mate together in general alignment.
INSERTING CAUSEWAY IN SEGMENTS
&,21
Surf conditions and swells are independent of open water Sea State conditions. If
wave height exceed five foot swells, operations should be curtailed. If the surf
conditions sustained five foot swells for an extended period of time, the FC should
be towed to a safe harbor. Failure to comply could result in equipment damage.

Causeway sections may be off-loaded and assembled into causeway segments in lengths
less than the total length of the causeway.The first causeway segment to be inserted on
the beach (the shore end) should be a minimum of five sections long. The more gentle the
bottom gradient, the greater the length of the causeway segment needed, allowing enough
depth of water at the offshore end for the SLWT to operate. The table below dictates
minimum lengths of causeway segments for beaching. The shorter the causeway, the
easier it will be to control and steer with the warping tug. For segments over four sections,
one or two additional tender craft may be required to steer the front end.
Beaching of the causeway should be timed to be at high tide. Beaching at other than high
tide can require extensive relocation and adjustments of the anchor and mooring lines as
the tide rises.
Ensure mooring lines are faked out on deck before beaching.
