Oceaneering nets Shell’s Appomattox flowline work

Shell has hired Oceaneering for the provision of services and products in support of the design, fabrication and installation of ancillary flowline hardware for the Appomattox development in  the U.S. Gulf of Mexico.

The scope of work for ancillary flowline hardware will include the procurement and installation of pre-lay and post-lay crossing mattresses, flowline jumper fabrication and installation, manifold installation, as well as the design, procurement, fabrication and installation of subsea buoyancy for flowline thermal expansion.

Oceaneering’s U.S. flagged vessel, the Ocean Evolution, scheduled for delivery in the latter part of 2017, is expected to be used to perform the offshore installation services in various phases starting late 2017 and ending sometime in 2019.

Oceaneering also expects to provide project management, engineering, remotely operated vehicle services, survey services, subsea tooling and global data solution services to Shell as needed for this work.

Roderick A. Larson, President and Chief Executive Officer of Oceaneering, said, “We are extremely pleased to expand our scope of supply, in addition to previously securing the control umbilicals contract, on this Shell deepwater Gulf of Mexico development.”

To remind, Oceaneering in 2015 won a contract to supply umbilicals for the Appomattox development.

The order for electro-hydraulic steel tube control umbilicals, totaling approximately 60 kilometers (37 miles) in length is planned to be completed in the third quarter of 2017.

Shell sanctioned the Gulf of Mexico project in July 2017.  The Appomattox platform will be Shell’s eighth and largest floating platform in the Gulf of Mexico.

The Appomattox development will initially produce from the Appomattox and Vicksburg fields, with average peak production estimated to reach approximately 175,000 barrels of oil equivalent (boe) per day.

The Appomattox development host will consist of a semi-submersible, four-column production host platform, a subsea system featuring six drill centres, 15 producing wells, and five water injection wells.
