The Greater Enfield

About the project

In 2016, OneSubsea ordered the umbilical and accessories from Nexans to develop the Greater Enfield development off the coast of Exmouth, Western Australia. The Greater Enfield Project is a joint venture between Woodside Energy Ltd and Mitsui E&P Australia Pty Ltd. The oil field is 60 km from the coast of Exmouth and will be developed using a 31 km subsea tie-back to the floating production storage and offloading (FPSO) facility. The six subsea production wells and six water injection wells will produce around 69 million barrels of oil equivalent (MMboe). OneSubsea will supply subsea pumps for the project.

Nexans' solution

Nexans delivered an innovative umbilical, 32 km in length combining power, signal and steel tubes as well as other services. The umbilical was manufactured at Nexans’ plants in Halden and Rognan, and was delivered in January 2018. It was installed at a depth down to 915 m. To maximize the cost-effectiveness of the single unit umbilical it comprised both dynamic and static sections.
