THEORY OF OPERATION
The floating causeway (FC) is a floating platform used during logistics over the shore (LOTS) operations on unde-
veloped beach area where flat underwater gradients are available, and no port area is available for direct shoreside
discharge of vessels. The FC consists of three major segments; trident pierhead extension, trident pierhead, and
causeway. The trident pierhead extension is the most seaward part of the floating platform and is used for loading and
unloading of more than one ocean-going sealift and lighter vessels. It may also be used to moor lighter vessels to the
FC. The trident pierhead, connected between the trident pierhead extension and the causeway, is a floating platform
used as a working area and a set up area for such items as the personnel shelter, diesel generator and light towers. The
causeway extends from the trident pierhead to the beach, where a combination beach/sea combination is connected.
The causeway is a docking pier head and provides a means of delivering containers, vehicles and bulk cargo ashore.
The FC may be set up in different configurations based on the operational situation and the best method of loading
One configuration is the force opening floating causeway or an administrative pier with a single roadway extending
from the beach out to 15 ft of water depth at the unloading and loading point. This configuration would be used for
single point loading or unloading of cargo, as no trident pierhead or trident pierhead extension is used.
The FC is held in place during LOTS operations by the floating causeway anchor mooring system (FCAMS). The
structure of the FC will withstand cargo loading and unloading through Sea State 2 conditions.
1O KW OR 15 KW SKID MOUNTED TACTICAL QUIET GENERATOR
Refer to TM 9-6115-642-10 for the theory of operation of the 10 KW diesel generator set.
Refer to TM 9-6115-642-10 for the theory of operation of the 15 KW diesel generator set.
The personnel shelter is contained in a 20 ft ISO container. Power is supplied to the shelter from the tactical quiet
generator through a power cable stored in the shelter and connected from a 100 amp connector on the backside of the
shelter to a 100 amp connector on the generator. The power provided by the generator supplies power to the electrical
distribution panel, which is cabled to the incinerator toilet, heating and cooling unit, lighting, fire suppression system
and to the ground-fault interrupter (GFI) receptacles in the personnel shelter.
6 KW TRAILER MOUNTED LIGHT TOWER
The lighting system consists of a self-contained, trailer mounted, 6 KW diesel generator which provides 6 KW of
power at 60 hz to four high pressure sodium, 1000 watt lamps. The power to each lamp is controlled by individual
switches on a control panel. The power is received from a 120 VAC - 2 phase alternator which is cabled through two
25 amp circuit breakers, to the switches, to a ballast box and connected by quick disconnects to the lights.
The VHF/FM transceiver is utilized for communicating between personnel during loading and unloading operations
on the FC. The transceiver has a frequency range of 156.025 to 163.275 mhz, plus 10 weather channels. The
transceiver has an RF power output with the CNB350 battery of 5.0 watts (high) and 1.0 watts (low). The operating
voltage is 7.2 Volts DC. Current drain in standby mode is 40 ma, in receive mode 200 ma, in the transmit mode
1.8 A (high power) and 0.7 A (low power). The battery life (5% TX, 5% rcv, 90% standby) is approximately 10 hrs
(high mode) and 15 hrs (low mode). The audio response is within +2/-8 of 6 dB/octave pre-emphasis characteristic
from 300 hz to 3000 hz. The AF harmonic distortion of the transmitter is 3%. The transmitter has a hum and noise
