H-Link Mooring Connectors: A More Reliable Fiber-Chain Connection

H-Link

The InterMoor Deepwater H-Link is composed of plates and pins that are specifically designed with a corrosion allowance for long term mooring.

H-Links are used for Fibre to Fibre or Fibre to Chain connection on a deepwater mooring line.

Over 2000 H-Links were installed in the deepest waters around the world. Projects include Williams GulfStar 1, Independence Hub, Technip Heidelberg, Equinor Astaa Hansteen, BP Juniper, and Shell Appomattox. For Shell Appomattox, InterMoor provided vendor coordination and production management for 94 H-Links. Each H-link weighed on average 7 t (15,653 lbs) and measured about 2m (6ft. 7in.). We work closely with Oceanside Equipment for the design, manufacturing plan specification (MPS), inspection and test plan (ITP) and documentation for the H-Links.

H-Links were developed starting in 2001 and replaced the old technology of shackles and thimbles. They provide

  • improved strength (recent MBL tests of over 2700te)
  • more reliable connection: all links undergo stringent fatigue and corrosion design analysis, and use carefully selected steel in line with class society grades (R4, R4S and R5).
  • easier on-deck installation features (hold off shackles, free deck standing and improved bolt/nut technology)

InterMoor holds the world record currently for the largest/strongest H-Link (7000kg/2744te).

All H-Links provided by InterMoor are fully DNV and ABS approved.
