ISO13729 Type B Bulwark Mounted Closed Chock

Description:

The closed chock is a type of ship’s mooring and towing fitting installed on the ship side to lead the mooring and towing rope from the ship’s inboard to outboard. The closed chocks are normally adopted for ships which use wire ropes. The radius of chock surface was designed based on the bending ratios of rope through the chock of not less than twelve times of the wire rope diameter.
