Type shackles
Split key
| Rivet pin
53
Split key shackle
Split-key shackles shall only be used to connect the bridle to the buoy, the swivel to the bridle, the riser to the swivel, and the mooring chain to the sinker. Split-key shackles shall not be used to connect lengths of chain. When connecting the swivel to the bridle, ensure that the head of the shackle pin lies toward the buoy counterweight to reduce wear.
54
Rivet Pin
Rivet-pin shackles (“heat and beat”) are used to connect lengthsofchain. Installtheshacklewiththepintowardthesinkerto preventcatchingthe“horsecollar”duringmooringretrieval. Rivet- pin shackles shall not be used in the chafe section of the mooring. When removing a rivet pin shackle to replace a section of mooring chain, cut the shackle pin instead of the shackle body. This will conserve the shackle body for future use and will only require replacement of the less expensive shackle pin. (
55
Swivel usage
Swivels. Worn or seized swivels shall be replaced. Swivels are mounted between the bridle and the riser chain with the round eye toward the bridle. If the mooring is prone to knotting an additional swivel can be used further down in the riser section of the mooring. However, swivels shall not be used in the chafe section of the mooring.
56
Sinker usage
Sinker. The sinker shall be replaced if the bail is worn to less than 1/2 of its original diameter, or the concrete is eroded or broken away. Sinker bails shall be made from steel bar stock. Sinkers with bails made from buoy chain shall be replaced.
