Jumbo to Install Wheatstone Subsea Structures
- Operations & Maintenance
Jumbo has signed a contract with Technip Oceania for the Installation of 13 Subsea Structures for the Chevron Wheatstone Project located offshore Australia.
The Subsea Structures comprise of Pipeline Termination Structures (PTSs), SSIV structures, Tee Protection Structures (TPSs) and Drill Centre Manifolds.
The Manifolds, to be installed at a maximum water depth of 240m, weigh up to 564T. Installation will be done by Jumbo’s Fairplayer, a DP2 Heavy Lift Vessel with 2 x 900T revolving deep-water 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.
“This award allows us to continue our long standing relationship with Technip in providing unique subsea heavy lift solutions. I would like to sincerely thank Technip again for the confidence placed in Jumbo and we are very much looking forward to working together towards a successful project completion,” said Roddy Lafontaine, Manager of Commerce Offshore.
The Chevron operated Wheatstone Field Development is located in Western Australia and situated 120 Nm 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.
