For at least the next three years, with an option for a further two, the joint venture will service the production facilities at the Bayu-Undan gas and condensate field, located in the Timor Sea, which is estimated to hold over 400 million barrels of hydrocarbon liquids and 3.4 trillion cubic feet of gas.

The facilities comprise a 14,000 tonne drilling, production and processing platform, a 11,500 tonne compression, utilities and quarters platform, a 1,400 tonne wellhead platform and a floating storage and offloading vessel.

“I am delighted that the Clough AMEC JV and ConocoPhillips have now signed-off on the above contract. This is a significant breakthrough for Clough in terms of building its Oil & Gas O&M [business],” said David Singleton, managing director and CEO of Clough.

“In conjunction with AMEC, the team effort to secure this contract and the execution of the mobilisation phase has been excellent. A multi-national workforce is being engaged from within S.E. Asia with management support from Perth, Darwin and Dili, Timor-Leste.”

Both companies have had recent success in securing similar contracts in the region with Clough part of a JV awarded the engineering, procurement and construction (EPC) contract by operator BP West Java for the APN Field Development located in the West Java Sea, in Indonesia.

AMEC and alliance partner Fluor also secured a similar engineering and procurement management contract for the Enfield floating production offloading and storage facility for Woodside Energy Limited, Australia.
