Offshore, Oil Services and Shipping

With Norway’s strongest team of lawyers in the oil and gas sector, we have a unique understanding of the industry. Our expertise also benefits our clients in the offshore, oil service and shipping sectors.

We have worked closely with the oil industry for over 40 years. We know the Norwegian continental shelf, we know the environment and frameworks that suppliers must comply with, and we know their clients – the oil companies.

As a large law firm, we have the breadth to provide assistance with any challenges encountered by the supplier industry, from establishing companies and structuring ownership, through financing and production of equipment and devices, to operations on the Norwegian continental shelf and cooperation with operator companies.

We are the preferred legal advisor for flagship suppliers within their sectors, such as the seismic company PGS and the technology powerhouse EMGS. We advise Teekay Petrojarl on their FPSO operations and assisted Teekay Corp. with its acquisition of Sevan Marine. We assisted the rig giant Transocean in Norway’s largest tax case. We assisted Single Buoy Moorings (SBM) in the Yme case, one of the largest and most complex construction disputes on the Norwegian continental shelf ever. In all these cases, our long experience assisting the triangle of oil companies–suppliers–governmental authorities has given us a competitive advantage.

With the country’s top oil and gas lawyers, we are ready to help even more companies operating in the petroleum sector.
