    HOVIK, Norway – Wintershall Norge has appointed DNV GL as independent verification body (IVB) and assigned the company third-party design verification scope for the subsea, umbilicals, risers, and flowlines (SURF) component of the Maria field development in the Norwegian Sea.

    The contract, set to run until end-2018, is potentially worth $ 3.95 million.

    Maria is an oil and gas discovery in 300-350 m (984-1,148 ft) of water in the Haltenbanken region. It will be developed through a subsea facility, connected via rigid flowlines and flexible risers to the Kristin production platform.

    Gas lift will be supplied from the Åsgard B complex via theTyrihans satellite facilities and sulfate-reduced seawater will also be supplied with injection pressure from the Heidrun field center. Maria is expected to enter production during fall 2018 and produce around 188 MMboe.

    The IVB model will be used for verification of safety-critical elements, in addition to conventional third-party verification of subsea production systems, pipelines, umbilicals, and risers.

    DNV GL’s scope covers all phases from design through commissioning, while its third-party verification role encompasses design and options for involvement in the fabrication/manufacturing/installation and commissioning phase.

    “This approach to handling verification is well known in the UK sector, but less used in Norway,” said Sture Angelsen, the company’s business development manager.
