Shell’s has awarded a number of contracts in recent months to advance the development of its Appomattox project in the Mississippi Canyon area of the deepwater Gulf of Mexico (GoM).
The project involves the construction and installation of Shell’s eighth and largest floating platform in the GoM. The Appomattox development host will comprise a semisubmersible, four-column production host platform, a subsea system featuring six drill centers, 15 producing wells, and five water injection wells. The project also calls for the construction of the 90-mi, 24-in. Mattox Pipeline, which will transport crude oil from the Appomattox host to an existing offshore structure in the South Pass area, and then connect onshore through an existing pipeline.
In March, Williams announced that it had reached an agreement with Shell and Nexen to provide deepwater gas gathering services for the Appomattox development. Williams says it will provide offshore gas gathering services to its existing Transco lateral, which will provide transmission services onshore to the Mobile Bay processing facility. Shell has also awarded contracts to Yokogawa for process control/process safety equipment and associated software; Oceaneering for electro-hydraulic steel tube control umbilicals; Danos for three boarding valve skid assemblies; and Lankhorst Ropes for the mooring lines. Production from Appomattox is reportedly scheduled to start by 2020.
