The 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.
The corner fenders are installed on protruding corners of the FC. The corner fender assembly has two parts and is
installed on the ISO corner fittings
FLOATING 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 vessels 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.
