HOUSTON -- Delmar Systems, Inc. successfully completed an eight-line disconnect of the mooring system on Seadrill’s West Phoenix semisubmersible drilling rig on the UK Continental Shelf. The rig disconnection was performed in an impressive two and a half hours without needing AHTS vessel assistance. The West Phoenix is currently under contract with Equinor for a three-well campaign, all of which are using Delmar’s Releasable Anchor Mooring System.

Delmar’s RAR Plus is the first ever dual-release action (acoustic and mechanical) rig anchor release. The RAR Plus is unique in that it allows for immediate rig transit after release with the RAR Plus’ nested in their trigger sleeves against the rig fairlead. This eliminates the weather window requirement that is typical for AHTS operations during a traditional rig disconnect.
