DEEP-WATER H-LINKS

2

H-LINKS HISTORY• Initial concept: Deep-water connector for the Gulf of Mexico spars and semi-

submersibles.

• Huge mooring systems require life spans of 27 years (plus) in a permanent position

• Connector design needed to allow for excessive corrosion (0.4mm per year over 27 years equates to 10.8mm of steel being lost in service).

• The first H-Links used in such a capacity were for the Ocean Confidence in the GoM on the InterMoor SEPLAs and Balltec connectors.

H-LINK

• The H-Link is forged and/or fabricated from Grade R4 material• Fully compatible with the chain links that are in the mooring system• Certifiable by LRS, DNV and/or ABS (depending on the mooring system requirements)• Strength calculations and FEA are undertaken to ascertain the life expectancy of the

units. • H-Link is taken to loads approximately 10% above the MBL (minimum breaking load)

of the chain.
