How IM™-H-Link works

Each IM™-H-Link mooring connector is designed for straightforward installation and long-term reliability. Featuring hold-off shackles, improved bolt systems and free-standing deck layout, the connector simplifies offshore handling and speeds up deck operations. 

H-Links connect chain to chain, or fibre rope to chain, enabling flexibility across hybrid mooring systems. Class approval and custom fabrication ensure the right fit, every time. 

The most robust mooring connector

Developed in 2001 to replace the outdated technology of shackles and thimbles, the H-Link has set new standards in strength, reliability, and ease of use.

Ensuring versatility and flexibility

The H-Link adapts to different rope and chain sizes, connecting fibre, chain or hybrid configurations with minimal interface complexity - ideal for evolving mooring systems across oil and gas and renewables.
