Aker Solutions’ maintenance, modifications and operations (MMO) business in Norway secured two contracts for work at North Sea fields operated by ConocoPhillips, according to a news release.

Aker received a framework agreement for five years to become ConocoPhillips’ main supplier of maintenance and modifications work offshore Norway. The agreement, which may be extended by up to three years, covers work on all installations at the Ekofisk and Eldfisk fields offshore Norway, starting in February, the release said.

The contract value depends on how much maintenance and modifications work is undertaken over the next five years and could range between NOK 1 billion (US $115 million) and NOK 3 billion ($346 million) in that period. Aker said the range neither represents a minimum nor a maximum amount but serves to illustrate a realistic, yet uncertain range.

Aker Solutions was also one of three companies awarded a contract to compete for work on large, complex modifications projects at these fields, the release said. This contract has the same fixed period and option as the framework agreement.

Work on both contracts will be managed and executed by Aker Solutions’ MMO unit in Stavanger and fabrication yard in Egersund. The agreements will also provide work for offshore employees.
