Technip-Subsea 7 Joint Venture Awarded Contract in New Zealand

Technip-Subsea 7 Joint Venture have been awarded a contract by New Zealand Overseas Petroleum Limited for the Tui Area development, located approximately 30 miles off the Taranaki coastline, New Zealand, in a water depth of 125 meters.

The joint venture contract, valued around US $30 million, includes the project management, engineering, transportation, installation and pre-commissioning of approximately:

•   15 kilometers of flexible flowlines(1), flexible risers(2) and associated mid water arch
     systems

•   15 kilometers of coiled tubing gas lift pipeline, spoolpieces, diverless connectors, and

•   15 kilometers of electro hydraulic umbilicals(3) and various associated components.

The contract will be executed by the joint venture teams based in Singapore and Perth (Australia) and Technip's operations and engineering center in Houston (Texas).

The flexible flowlines and risers will be fabricated by Flexi France, one of Technip's flexible pipe plants located in Le Trait (France), under a separate supply contract.

(1) Flexible flowline: a flexible pipe, laid on the seabed, which allows the transportation of oil/gas production or injection of fluids. It is generally an infield line, linking underwater structures to each other or to a fixed or floating production facility. Its length can vary from a few hundred meters to several kilometers.

(2) Flexible riser: a pipe or assembly of flexible 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.

(3) Umbilical: an assembly of hydraulic hoses which can also include electrical cables or optic fibres, used to control subsea structures or remotely operated vehicles (ROV) from a platform or a vessel.
