FLOATING CAUSEWAY
DESCRIPTION AND DATA
EQUIPMENT CONFIGURATION
General
Following are two typical configurations that may be used as floating causeway platform during logistics over the
shore (LOTS) operations. The trident pierhead is used for loading and unloading ocean going sealift vessels. It is
capable of supporting two M-1 Abrams Tanks and one sealift vessels’s cargo ramp foot on the platform surface. The
trident pierhead extension is used by lighter vessels to moor to the floating causeway.
The force opening floating causeway is an administrative pier used to get to 15 ft of water depth and does not use a
trident pierhead. It is a floating platform for loading and unloading ocean-going sealift vessels. The causeway
consists of one or more intermediate sections connected length wise and connected to a combination beach/sea end
section. The length depends on how far offshore, from the beach, the causeway must extend to give the required
water depth. The force opening floating causeway operating conditions are: Sea State 2 with five foot waves and a
current of two knots
