TM 55-1945-205-10-40002 00 50002 00MOORING BITTThe mooring bitts provide securing points on the trident pierhead for lighters and for fenders. They attach to the platform at the module connector locks. The bitts are designed for up to a 6 in. circumference mooring line. The mooring bitts are lifted and installed using the forklift adaptor. Each bitt weighs 235 lbs and is 6 ft 5 in. long. Eight mooring bitts are provided with the FC system.FENDERS (WITH ATTACHMENT CHAINS)There are three types of fenders authorized for use on the FC: 5 ft X 10 ft, 4 ft X 12 ft and 3 ft X 5 ft. The 5 ft X 10 ft fender weighs approximately 1500 lbs. The 4 ft X 12 ft fender weighs approximately 1450 lbs. The 3 ft X 5 ft fender weighs approximately 300 lbs. CORNER FENDERSThe corner fenders are installed on protruding corners of the FC. The corner fender assembly has two parts and is installed on the ISO corner fittingsFLOATING CAUSEWAY ANCHOR MOORING SYSTEM (FCAMS)The FCAMS is designed to hold the floating causeway in place during logistics over the shore (LOTS) operations in sea conditions up to Sea State 3. The offshore mooring leg is designed to perform in soft soils and sand. The onshore mooring leg is designed to perform in soft soils, sand and competent rock.In addition to Sea State, the capability of the FCAMS to hold the floating causeway in position is highly dependent on the alongshore current speed and number and type of vessels mooring to the floating causeway. It is also dependent on the water depth at the vessel’s location. The complete system, which has 16 offshore mooring legs and four onshore mooring legs, is required for a full floating causeway that is 1500 ft long. The following table shows the estimated current speeds for the FCAMS to hold the floating causeway in place when one or two lighters are moored alongside the five string wide trident pierhead extension of the floating causeway.
