Jumbo signed a contract with Technip Oceania for the installation of 13 subsea structures for the Chevron Wheatstone Project. The subsea structures comprise of pipeline termination structures, subsea isolation valve structures, tee protection structures and drill center manifolds. The manifolds, to be installed at a maximum water depth of 240m, weigh up to 564-tonnes.
Installation will be done by Jumbo’s Fairplayer, a DP2 heavy lift vessel with two 900-tonne revolving deepwater cranes. Fairplayer is anticipated to commence its activities offshore Western Australia in April/May 2015.
After a full summer season operating in the North Sea and Mediterranean, this project enables Jumbo to continue its offshore activities in the Southern Hemisphere.
Wheatstone
The Chevron-operated Wheatstone field development is located in Western Australia's Pilbara region and is situated 120nm north of Onslow. The water depth at site ranges from 73m to 240m. Wheatstone will be developed using a subsea gas gathering system that is tied back to the recently-installed Wheatstone platform. Gas will be exported from the platform to the onshore LNG facility through a dedicated trunkline. First gas production/LNG start-up is expected in 2015.
