The skirt contains the six chain stoppers housings. Self-aligning chain stoppers for chains are designed to allow for the chain stopper to align itself according to the chain angle and therefore reduce the risk of Out-of-Plane Bending (OPB) failure of the mooring chain. Self-lubricating plain bearings are inserted at the chain stoppers trunions ...
Also, due to the position of the chain stoppers, the clearance between the tanker bow and the anchor chain catenary is larger, thus reducing the risk of tankers running into and damaging the anchor chain layout. The centre of gravity of the turret buoy is relatively low, providing higher stability during installation and hook-up of the buoy.
Uses: The Rolling Hitch Knot is useful to take the strain off a rope with a foul turn on a winch. It can be used to relieve the strain on a hawser while the "Bitter End" is transferred to the "Bitts" but the Rat-Tail Stopper is better. It can also be used to make a Midshipman's Hitch, an adjustable loop in the end of a rope with many uses on boats, e.g., to act as a spring line to a ...

Chain stopper, which is also known as cable stopper, is a device used to secure the anchor chain when riding at anchor, because the windlasses are not designed to hold high loads while a boat is at anchor, the chain stopper can relieve the strain on the windlass and secure the anchor in the housed position in the hawse pipe.
Bow chain stopper. A device mounted on tanker forecastle deck for securing a chafe chain. Ships likely to trade to Single Point Moorings should be equipped with bow chain stoppers designed to accept 76 mm chafe chain.
Chain stoppers—The chain stopper connects the top end of the mooring line to the bottom of the turret structure (chain table). The top segment of the mooring line, typically chain, passes through the chain hawse and terminates at the chain stopper. 3.
linked to the seabed via one chain or an articulated rigid structure. The floating body of the system is such that the ratio height / diameter is large. • Mooring Legs: Mooring legs systems are flexible linear elements (e.g. chains, polyester ropes, wire ropes) connected to a buoy or a turret. In the case of a
System components include the anchor, anchor chain, anchor shackles, anchor roller, anchor rode and windlass. Anchor rodes can be all chain or a combination of rope and chain. The anchor rode is secured to a boat cleat, Samson post or held in place by a chain stopper. Equipping your boat for anchoring includes installing a boat ladder.

In order to avoid damage to submarine pipelines and anchor chains, the ships anchor should not be dropped except in an extreme emergency. When the tanker is close to the SBM or FSO, the messenger should be lowered to a mooring launch for connection to the pick‐up rope. When the launch is clear of the system, it can begin to be winched in.

Chain may also be used, especially in anchorages that are primarily rock or coral, which may cut a nylon line. A length of chain should be used between the anchor and a longer length of line. The chain will add weight to set your anchor without making it too heavy to lift manually, while serving to exert a horizontal pull on the anchor to set it.
Typically chafe chains form a single chain of approximately 8 metres or more in length, composed of 76mm stud link chain. If through-type chain support buoys are utilised the length of the chain may have to be increased. Each chain should terminate, at the shipboard end with an oblong plate for connecting the chain to the pick up rope bow shackle.
