”As one of the most recognisable names in the Norwegian market, it is hardly surprising Thommessen is well regarded in the energy and infrastructure space. Industry figures are quick to praise the quality delivered by the team and describe the service offered and the capability of the lawyers involved as excellent”, the guide writes.

In addition, Jacob F Bull, Rune Solberg and Jens Naas-Bibow are highlighted as ”Leading Lawyers” within their respective fields of law.

Here are some comments from this year’s guide:

  • ”A team led by Rune Solberg continues to advise Petoro on the development of the Johan Sverdrup oil field, the largest discovery in Norway for a number of years”.
  • ”Jacob Bull and his team continue to provide assistance to Lyse Produksion regarding the procurement and construction of a new hydropower plant, Lysebotn II”.
  • ”Jens Naas-Bibow, meanwhile, also continues to advise NorthConnect in association with the contemplated establishment of an HVDC interconnector between Norway and the UK, a strategically important matter for the country and the region”.
