Wintershall Norge managing director Bernd Schrimpf said: "We are constantly gaining more and more experience in the development of projects on the Norwegian Continental Shelf.

“Working closely with AkerBP has been very constructive and efficient. We would like to congratulate the entire team, which has succeeded in transferring the field into production on time and to budget.

“Wintershall can take this experience and apply it to our own-operated Maria and Skarfjell projects.”

The field comprises three discoveries including Ivar Aasen, West Cable and Hanz. The first two fields are being developed under phase one while the Hanz field is part of the second phase.

Developed with a production facility on the seabed at a water depth of 110m, the Ivar Aasen field will produce oil and gas, which will undergo final processing on the Edvard Grieg field.

Production from the field is estimated reach 23,000boe per day when both the phases are completed.
