Wintershall Norge AS is the operator of the Maria field, which is an oil and gas field on the Halten Terrace in the Norwegian Sea, around 45 km south of Heidrun.
The field will be developed using a subsea solution and tied back to the production facilities for Kristin, Heidrun and Åsgard B. Maria is Wintershall's first field development on the Norwegian Continental Shelf.
On 19 November 2015, the PSA carried out an audit of how Wintershall will fulfil both the regulatory and the company's own requirements in the design engineering of the seabed facilities and pipeline systems for the Maria field.
The audit identified no non-conformities or improvement points in the project execution.
