Wintershall lets multiline Maria contract

Wintershall has let a $300-million contract to Subsea 7 for pipeline and subsea construction in its multihost development of Maria oil and gas field in the Norwegian Sea (OGJ Online, May 5, 2015).

The contract includes an engineering, procurement, construction, and installation agreement for three pipeline systems linking Maria with the Kristin, Heidrun, and Asgard B production platforms.

Kristin will process production, receiving the Maria well stream through a 26-km flowline with a direct electrical heating cable. Water for injection will come from Heidrun via a 46-km, plastic-lined pipeline. Lift gas will come from subsea Tyrihans field through a 22-km pipeline from the Asgard B platform.

Maria field lies 230 km offshore in 300 m of water.

Also under the contract, Subsea 7 will install two integrated templates, subsea manifolds, and the production riser base at Kristin supplied by FMC Kongsberg Subsea AS under a frame agreement with Wintershall. Subsea 7 also will install static control umbilicals supplied by FMC Kongsberg between Kristin and the Maria templates.

Wintershall, operator, with a 50% interest, expects to produce 180 million boe of oil and gas from Maria field, mostly oil. It hasn’t reported production rates.

Petoro AS holds 30%, and Centrica Resources (Norge) AS holds 20%.
