ISO 13713 Type B Casting Steel Mooring Chock Ship Towing Equipment

Description:

ISO 13713 Type B Casting Steel Mooring Chock Ship Towing Equipment is made according to the ISO 13713 standard and is for mooring purpose installed on the shipside to lead the mooring rope from the ship's inboard to outboard. It is welding on the bulwark. The mooring chocks are normally adopted for ships that use nylon or other synthetic ropes rather than wire ropes considering the small bending ratio (for wire rope see ISO13729 closed chocks). The tensile strength of the rope is reduced depending on the bend radius through the chock in accordance with the rope manufacture's guidelines. All surfaces, including welding, shall be free from any visible flaws or imperfections and in contact with the ropes, shall be free from surface roughness or irregularities likely to cause damage to the ropes by abrasion. The chock should be coated externally with an anti-corrosion protective finish.

Main Technical Specification:

  1. Standard: ISO 13713
