Mr Sondre Dyrland > Wiersholm > Oslo, Norway > Lawyer Profile

Hans Augun Parmann heads up Wiersholm’s construction offering, which advises clients on tender processes, contract negotiations, project executions and contentious mandates. The group has particular expertise in advising on large highway PPPs, with Parmann being a key contact here. Ronny Lund handles contractual, administrative and procurement issues related to offshore and onshore construction projects, working alongside Sondre Dyrland; the two also handle contentious mandates in this space.

Lauded by clients for its ability to bring ‘a wealth of experience and technical know-how to transactions‘, the energy team at Wiersholm runs the gamut of renewable and traditional energy work, handling commercial agreements, project financing work, regulations, and project development. Inge Ekker Bartnes and Jon Rabben jointly oversee the renewables offering; Bartnes is recommended for work relating to M&A, financing deals, and financial restructurings, while Rabben assists domestic and international clients with regulatory issues, contract negotiations, and corporate matters. On the oil and gas front, the team’s expertise spans the full range of petroleum law and regulatory work, as well as commercial agreements, disputes, and transactional mandates. Sondre Dyrland oversees the oil and gas group and has extensive expertise in petroleum law and contractual matters, while Thomas Naalsund handles contentious work. At associate level, the ‘technically very sharp’ Svanhild Vesterheim specialises in regulatory matters in the renewable energy sector. Torkjel Grøndalen joined the practice in early 2024 from Advokatfirmaet Schjødt AS.

Under the joint leadership of Karl Even Rygh and Kristine Hasle, the interdisciplinary offshore construction and shipbuilding practice at Wiersholm draws on experts from various practice areas across the firm to provide a full-service offering with notable strength in dispute resolution, including acting in international arbitration proceedings; Christian Hauge is a key name here. Field development and project execution feature heavily in the group’s workload, with the team regularly acting for both international and domestic oil services contractors operating on the Norwegian Continental Shelf. Sondre Dyrland takes point on offshore construction matters, while associate Mattias Grieg ably assists with transactional work in this space.
