Mette Duffy is an associate in the Energy, Power and Natural Resources Practice Group in Haynes Boone’s London office.

Her practice focuses on the energy and offshore shipping industry. Mette advises on tenders, contracts and issues arising on high-value and complex projects in the oil and gas, ship-building, offshore construction, drilling, floating production (particularly FPSO) and oilfield services sectors and on offshore charterparties. Mette has also brought to bear her oil and gas/maritime experience in advising on renewables projects.

Mette is primarily focused on risk avoidance/mitigation. Her transactional work is informed by extensive dispute resolution experience and sound knowledge of where problems typically arise. Mette is at all times focused on helping clients to achieve the best commercial solutions.

Where disputes cannot be avoided or resolved at an early stage, Mette has assisted clients with heavyweight international proceedings, most recently in the offshore construction and floating production sectors. She has experience of arbitrations under the major rules (LCIA/ICC/LMAA/UNCITRAL) and litigation in the English High Court (Commercial Court/TCC).

Prior to joining Haynes Boone, Mette was a Managing Associate in the Energy & Infrastructure Group of another large international law firm.
