Aqualis Offshore has completed the jacket installation engineering of an 1800T steel jacket structure offshore Bahrain as part of the Bahrain LNG Import Terminal.
Aqualis Offshore delivered the project in cooperation with APMC, who were in charge of the transportation and installation contract on behalf of its EPC contractor client, GS E&C.
Aqualis Offshore was contracted by GS E&C to provide loadout, transport and offshore installation of the jacket.
Aqualis Offshore’s scope of work provided full engineering services related to the loadout, transportation and float off operation, towing, positioning, lowering to the seabed and buoyancy tank removal, including all marine procedures.
An innovative approach for jacket installation in shallow water was applied by engineering buoyancy tanks to allow the jacket structure to be floated-off the transport vessel, towed to site and lowered to the seabed through ballasting, the company explained.
“The jacket, with three of six main piles slotted into the jacket legs, and its buoyancy tanks were loaded out onto pre-installed grillages on the submersible heavy lift vessel using trailers,” said Phil Lenox, director – Asia Pacific, Aqualis Offshore.
The Wish Wayheavy lift vessel was utilized to transport the jacket from SKMT (Samkang M&T) in Goseong Yard, South Korea to its destination at its final location offshore Bahrain at 20 meters water depth.
Aqualis Offshore managed the jacket installation project out of its Singapore office. The associated topside floatover installation will be executed in August 2018.
