Paris - Pipeline supplier Technip announced 18 May that it has signed an agreement, worth about €30 million ($38 million), with Statoil ASA to make and install a pipe-in-pipe flowline to support the Marulk field development. Statoil is carrying out parts of this project on behalf of the operator Eni.
The Marulk field, in the Norwegian Sea 30 km southwest of the Norne field, is at a depth of 365 m. Technip said the initial development will consist of two wells tied back to the Norne floating production, storage and offloading vessel (FPSO). This 30.5-km tie-back is based on the use of Technip's proven pipe-in-pipe technology, said the French group's statement.
Technip's operating centre in Oslo, Norway,will carry out the pipeline fabrication, which will be completed by Technip's Spoolbase in Orkanger, Norway. The installation will be done by Apache II, a newly converted vessel from Technip's fleet, in the first half of 2011.
Technip explains that pipe-in-pipe flowlines are steel pipe assemblies consisting of a standard production pipe surrounded by a so-called carrier pipe. The gap between the carrier and production pipes is filled with an insulation material. As the insulation is protected from the external pressure by the carrier pipe, a high thermal performance material can be used, said the supplier.
According to Technip, the technology "provides the level of insulation necessary for economical installation and the level of flow assurance needed for effective production in deep and ultra-deep water."
Technip claims to offer a comprehensive portfolio of project management, engineering and construction for the oil & gas industry, with 23 000 employees around the world, integrated capabilities and proven expertise in underwater infrastructures (subsea), offshore facilities (offshore) and large processing units and plants on land (Onshore).
The La Defence, Paris-headquartered supplier is present in 48 countries, with has operating centres and industrial assets (manufacturing plants, spoolbases, construction yard) on five continents, and operates its own fleet of specialised vessels for pipeline installation and subsea construction.
