Delmar Systems has expanded its portfolio of releasable mooring solutions by introducing the Fairlead Locking Bolster Hook — an auto-engaging technology that enables fairlead locking during transit without anchor handling vessel (AHV) support.

“RAR PLUS has new surpasses 1000 PLUS releases and the lessons learned have brought Delmar to develop the  bolster hook to allow for immediate transit readiness in harsh environments. Avoiding damages to the fairleads and eliminating the need of vessels during disconnection,” said John Shelton, CEO of Delmar Systems. “Our team engineered and tested the bolster hook from scaled models to full-scale offshore trials, and we’re proud to see it performing as safely and efficiently as our engineers intended.”

The hook is designed to integrate seamlessly with Delmar’s flagship RAR PLUS system without rig modifications. Its one-hook design supports reliable, efficient deployments and contributes to safer, more autonomous rig operations.

The hook has already been deployed at five locations in the North Sea and will soon be deployed in Australia, proving its ability to reduce costs by eliminating AHV support and accelerating rig moves. The Bolster Hook is now available globally as an add-on to the RAR Plus.
