Project Description
ISO13713 Mooring Chocks Type B Bulwark Mounted
ISO13713 Type B Bulwark Mounted Chock
ISO13713 Type B bulwark-mounted chock is a specialized marine mooring chock, engineered and manufactured strictly in accordance with the ISO13713 standard. Designed for bulwark-mounted installation on ships, this Type B chock is specifically optimized for nylon and other synthetic ropes, delivering reliable performance for ship mooring and towing operations.
Unlike other chock types, the ISO13713 Type B bulwark-mounted chock features a unique bulwark-mount design, allowing it to be securely installed on the ship’s bulwark to guide mooring ropes from inboard to outboard. Its precision-cast structure ensures minimal rope wear, preserves synthetic rope tensile strength, and adapts to the bending ratio requirements recommended by rope manufacturers.
Key Features
- Compliance: Fully meets the ISO13713 standard for mooring chocks, ensuring international marine safety and quality requirements.
- Unique Design: Bulwark-mounted installation, perfect for ships requiring secure, space-saving mooring guidance.
- Rope Compatibility: Optimized for nylon and synthetic ropes (not suitable for wire ropes; refer to ISO 13729 for wire rope chocks).
- Material: High-grade cast steel, ensuring durability and corrosion resistance in harsh marine environments.
- Finishing: Hot-dip galvanized (HDG) or black tarred painting, extending service life in high-salinity conditions.
- Function: Guides mooring and towing ropes smoothly, reducing tension loss and preventing rope damage.
- Customization: Available in customized sizes to match different ship bulwark dimensions and mooring requirements.
Applications
The ISO13713 Type B bulwark-mounted chock is widely used for:
- Commercial cargo ships and offshore workboats
- Yachts and leisure vessels (with synthetic mooring ropes)
- Port and marine mooring operations
