Bulwark mounted ISO13729 closed mooring chock is a special type of anchor hole at a vessel’s bow bulwarks. It is specially used to guide the mooring ropes of large ships. The closed chock is made of high quality cast steel and bolted or welded to the hull. It is used to lead the mooring and towing rope from the ship’s inboard to outboard.

As a large ship mooring chock, it meets the outfitting design by the requirement of Panama Chock. This closed chock is very important mooring equipment. In the process of mooring ship, it bears huge loads. 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. Because this type of mooring chock is closed, the cable will not jump out.

Customers can choose the suitable ISO13729 closed chock according to the size of the vessel and the diameter of the pipeline. In addition, we can also provide a series of customized solutions.

  • All surfaces of the closed chocks including welding shall be free from any visible flaws or imperfections.
  • All surfaces in contact with the ropes shall be free from surface roughness or irregularities likely to cause damage to the ropes by abrasion.
  • The closed chocks shall be coated externally with an anti-corrosion protective finish.
