Technip and Subsea 7 awarded subsea installation contract for the CWLH redevelopment project in Australia
Technip and Subsea 7 (OSE Symbol: SUB), have been awarded a subsea installation contract by Australia’s largest publicly traded oil and gas exploration and production company, Woodside Energy Ltd., for the Cossack Wanaea Lambert Hermes (CWLH) redevelopment project in Western Australia.
The overall CWLH redevelopment project involves the replacement of the oil-producing Cossack Pioneer floating production storage and offloading (FPSO) facility, located offshore in the Carnarvon Basin, as well as the refurbishment of associated subsea infrastructure.
The Technip and Subsea 7 contract consisting in the refurbishment of associated subsea infrastructure covers:
- Project management,
- Recovery of three risers(1) and installation of three replacement risers,
- Installation of 20 kilometers of flowlines(2),
- Riser base rectification works, and
- Pre-commissioning assistance.
The project team is based in Technip’s office in Perth, Western Australia. The flowlines and risers have been manufactured in Le Trait, France, one of Technip’s flexible pipe plants. Offshore installation is scheduled to start in the fourth quarter of 2010 using the Venturer, a construction vessel from Technip’s fleet and the Nor Australis diving support vessel contracted to Woodside.
(1) Riser: a pipe or assembly of pipes used to transfer produced fluids from the seabed to surface facilities, and transfer injection or control fluids from the surface facilities to the seabed.
