Nexans to supply umbilical for Woodside’s Greater Enfield project

Nexans, a supplier of cables and umbilicals for the oil and gas industry, will deliver umbilical and accessories to OneSubsea for a project offshore Australia. 

Nexans said on Monday that OneSubsea ordered the umbilical, that is 32 km long and combining power, signal and steel tubes, to develop Woodside’s Greater Enfield development off the coast of Exmouth, Western Australia.

Earlier in July, OneSubsea secured a contract from Woodside Energy to supply a subsea production system and a dual multiphase boosting system for the Greater Enfield Project.

Nexans stated that the project, worth 20 million euros (around $22M), is its first in Australia.

The company added that the umbilical will be manufactured at its plants in Halden and Rognan, and will be delivered in January 2018. It will be installed at a depth down to 915 m.

The single unit umbilical will comprise of both dynamic and static sections which will, according to Nexans, maximize cost-effectiveness.

Dirk Steinbrink, Senior Executive Vice President of High Voltage & Underwater Cable Business Group at Nexans, said: “We are excited to expand our reach around the world and our strong relationship with OneSubsea. Nexans has pioneered the development of power umbilicals which are a cost-effective way of supplying power, control, and other functions to the sea floor.”

The Greater Enfield Project is a joint venture between Woodside Energy (operator, 60%) and Mitsui E&P Australia (40%). It was given the go-ahead for development last month. It is located 60 km from the coast of Exmouth, and the development will consist of six subsea production wells and six water injection wells.

The oil field will be developed using a 31 km subsea tie-back to the Ngujima-Yin floating production storage and offloading (FPSO) vessel, located over the Vincent oil field.

The project is targeting development of gross 2P reserves of 69 MMboe from the Laverda Canyon, Norton over Laverda and Cimatti oil accumulations.
