Subsea 7 Sets Up Maria Pipelines

Subsea 7’s installation vessel, Seven Oceans, has landed the last production pipeline on the seabed at the Maria field in the Norwegian Sea, the operator Wintershall informed through social media.

The subsea umbilicals have also been recently installed, utilizing the capabilities of the Seven Arctic vessel.

Wintershall has now finished laying almost 100 kilometers of underwater pipelines for its flagship development in Norway.

Located in the Haltenbanken area of the Norwegian Sea, the Maria reservoir will be linked via subsea tieback to three existing platforms in the area.

The Maria well-stream will go to the Kristin platform for processing while supply of water for injection into the reservoir will come from the Heidrun platform and lift gas will be provided from Åsgard B via the Tyrihans subsea template.

Processed oil will be shipped to the Åsgard field for storage and offloading to shuttle tankers. Gas will be exported via the Åsgard Transport System to Kårstø.

First oil is expected in 2018, with a possible acceleration into the first half of the year.

Wintershall Norge holds 50% share, Petoro has a 30% share and Centrica Resources (Norge) owns the remaining 20% in Maria licence.
