Glenn Kangisser is a partner with extensive international and multi-jurisdictional experience in the offshore, oil and gas, and shipping industries (contentious and non-contentious) with a particular focus on upstream exploration and production and the transportation of oil and gas. His practice emphasis is on offshore drilling and he is involved in all aspects in the “life cycle” of a drilling unit.

Glenn is a recommended lawyer in the international arbitration and oil and gas sections of the 2017 UK edition of The Legal 500, Legalease, the international directory of law firms. Legal 500 reports that Glenn is a ‘key name’ in international arbitration and a 'natural problem solver' who was ‘also singled out for his highly commercial attitude’ in oil and gas.

Glenn regularly advises clients on offshore drilling and construction disputes in the English High Court as well as in arbitrations under the LCIA, LMAA and ICC rules. Glenn has also negotiated contracts for the construction, sale, operation and employment of drilling units in the UKCS, US Gulf of Mexico, West Africa, Brazil and the Far East.

Having a sector focus enables Glenn to advise on both commercial projects and disputes in this sector. Being able to negotiate contracts and handle disputes allows Glenn to help clients find commercial solutions either to minimize the risk of potential disputes or, where these can’t be avoided, to help the clients achieve the best possible commercial outcome.

Glenn is active member of the International Association of Drilling Contractors (IADC) and is currently helping the IADC update their offshore daywork drilling contract. Glenn also writes regularly on various topics of interest for industry publications, including Lloyd’s List.
