ISO 13729 deck mounted closed chock is a type of ship’s mooring and towing fitting installed on the shipside to lead the mooring and towing rope from the ship’s inboard to outboard. It can be either mounted directly onto or into the hull, or alternatively can come supplied with a base plate to be bolted to a plinth.

The closed chocks are normally adopted for ships that use wire ropes. The radius of the chock surface was designed based on the bending ratio of rope through the chock of not less than twelve times the wire rope diameter.

The closed chock is used specifically for the guidance of rope mooring lines on board a large ship or vessel. Due to its heavy-duty use, the chock is manufactured from high quality cast steel in various grades depending upon the particular application and loading required.

ISO 13729 deck mounted closed chock is made of steel casting material having a yield point of not less than 235 N/mm2 or equivalent. The carbon contents of the steel casting shall not be more than 0.23 % considering weldability. There are no visible flaws or imperfections on the surface, and without roughness or irregularities in contact with the rope will damage the rope due to wear.
