Shipping and Offshore

The shipping and offshore markets are characterised by substantial values, complex contractual structures and increasing regulatory requirements. At the same time, the industry is directly affected by geopolitical developments and is undergoing a significant technological transformation as well as a green transformation. We assist shipowners, charterers, offshore operators, yards, financial institutions, investors, brokers and insurers in navigating this landscape – from strategic assessments and contract negotiations to disputes, casualties and complex regulatory issues in Norway and internationally.

The maritime industry has been a key driver in the development of Norwegian business, and Norway is today one of the world’s largest shipping nations measured by value. Our advice is closely anchored in developments in maritime law and in the industry’s international framework conditions. With an extensive network in the sector, both in Norway and internationally, we ensure that clients receive the best local assistance, wherever in the world their business operates.

Cross-disciplinary collaboration

Shipping and offshore projects often raise issues across several legal disciplines. Our services are therefore organised in cross-disciplinary teams, tailored to the individual matter and the client’s needs.

Our shipping and offshore lawyers work closely with specialists in areas such as shipping taxation including tonnage tax, marine insurance and dispute resolution. In the event of casualties and maritime accidents, we also provide swift and operational assistance, drawing on experience from handling urgent situations and coordinating with authorities and other involved parties.

Recognised in Norwegian and international rankings

Thommessen is regularly ranked among the leading law firms within shipping and offshore by recognised international rankings such as Chambers & Partners and Legal 500, as well as Norwegian rankings such as Prospera and Kapital’s annual lawyer survey. Several of our lawyers are also individually recognised for their expertise in maritime law, marine insurance and offshore-related matters.
