Practice Areas

Sean is instructed in a wide range of contractual disputes, with a particular focus on shipping, shipbuilding and energy-related issues. He is especially well-known for highly technical and complex cases, involving significant sums, and leading large teams. He deals with shipping disputes of all shapes and sizes (whether involving dry bulk or liquid cargoes, containers, towing, support vessels, or the carriage of passengers or livestock) and the full range of shipbuilding and ship sale and purchase cases (covering everything from luxury yachts and cruise ships to semi-submersible drilling rigs). He also represents oil majors, petrochemicals traders and contractors in “energy” disputes (e.g. commodity sales, farm in/ farm out agreements, share purchase agreements, drilling contracts, distribution agreements, etc.). Other areas of expertise include insurance/ reinsurance (both marine and non-marine) and professional negligence (esp. brokers, solicitors and accountants/auditors). He regularly appears before the Commercial Court in London and in arbitrations, and is now regularly appointed as arbitrator, both ad hoc and under the auspices of the various arbitral bodies around the world (ICC, LCIA, UNCITRAL, LMAA, SIAC).
