Woodside has awarded Technip with the contract for development of its Greater Enfield Project in offshore Western Australia.
Technip did not disclose the value of the contract, but said it was in the range of €250m to €500m.
The Greater Enfield project itself is a subsea tie back to the Ngujima-Yin floating production storage and offloading (FPSO) unit, moored over the Vincent field, which is 50 km offshore from Exmouth in Western Australia.
Woodside’s concept consists of up to 14 wells in total, which will be tied back to the existing FPSO via a 16-inch rigid production flowline and a 10-inch flexible production riser.
Technip’s contract covers project management, design, engineering, procurement, installation and pre-commissioning (EPIC) work, which will be conducted at a water depth of between 340 and 850 metres.
Technip will install a carbon steel production flowline, a carbon steel water injection flowline, flexible risers and around 82.2 km of flowlines and 38.9 km of dynamic and static umbilicals.
The work also comprises the installation of subsea structures and valves, and a multi-phase pump system, as part of modifications to the FPSO to allow it to handle the Greater Enfield fluids.
The flexible pipes will be manufactured by Asiaflex Products, Technip’s manufacturing plant in Tanjung Langsat, Johor, Malaysia. The umbilicals will be supplied by Technip Umbilicals’ facility, which is located in Newcastle, UK.
The offshore installation utilise several vessels from Technip’s fleet and is scheduled for completion in 2018.
