Subsea connector specialist, First Subsea has completed the installation of the twelve mooring connectors for the Thunder Hawk DeepDraft Semi, a semisubmersible floating production unit (FPU) in 6,050 feet (1,800m) in the Gulf of Mexico.

The Thunder Hawk FPU is anchored with a polyester rope-chain spread mooring system connected to twelve driven piles by Ballgrab mooring connectors. The mooring connectors' receptacles were first pre-installed in a docking porch on each of the driven piles. Once the Thunder Hawk FPU was in position, the male Ballgrabs were attached to the end of each of the mooring lines were connected.

Clay Thompson, Installation Manager, SBM Atlantia Inc., was responsible for supervising the installation of the mooring lines. He commented, "The First Subsea team did a great job; the Ballgrab mooring connector installations went very well. By pre-installing the female connectors on the piles, we were able to attach the male connector within a few minutes once it was within a few feet of the female connector."

DeepDraft Semi is a registered trademark of Atlantia Offshore Ltd.
