Glenn Kangisser

Glenn Kangisser handles projects and disputes for clients in the offshore, oil and gas, and shipping industries, with a focus on upstream exploration and production and the transportation of oil and gas. A leader in the offshore drilling sector, Glenn brings substantial depth of experience and market knowledge to his projects. Clients appreciate his ability to be involved in all aspects in the lifecycle of a drilling unit, from the design and construction phase through operations and maintenance, to disposition, conversion, or recycling.

Adept at both negotiating contracts and handling disputes, Glenn helps clients find commercial solutions either to minimize the risk of potential disputes or, where these can’t be avoided, to help them achieve the best possible commercial outcome. He regularly advises clients on disputes in the English High Court, as well as in arbitrations under the LCIA, LMAA, and ICC rules. With a truly international practice, Glenn has also negotiated contracts for the construction, sale, operation, and employment of drilling units in the UKCS, U.S. Gulf of Mexico, West Africa, Brazil, the Middle East, and the Far East.

Glenn is regularly involved in cases of exceptional size and significance. Recently, he led his team in the largest arbitration ever handled by the firm, obtaining a London arbitration award in excess of US $400 million for a European drilling contractor client in proceedings against a South Korean shipyard. This arose out of the disputed termination of a drilling rig construction contract. Glenn was also involved in a major force majeure case under English law, securing for Seadrill Ghana Operations Ltd. an English High Court judgment worth in excess of US $270 million, plus interest and expenses. The case related to the disputed termination of a drilling contract for alleged force majeure. Glenn has also been involved in some of the largest and most significant offshore drilling projects over the last decade.

Glenn heads Haynes and Boone’s oil and gas team in the UK and is recommended by The Legal 500, 2023-2024 (Legalease) where he is recognised as a specialist in the space with exploration and production his key focuses. Clients commented that the team led by Glenn has “exceptional capability and knowledge of upstream energy sector law in support of operations and commercial activities” and “a deep understanding of the legal, commercial and practical issues involved in upstream and downstream transactions”.
