William has extensive experience in maritime and construction litigation and arbitration matters for clients in the shipping, offshore oil and gas and energy industries. Since 2004, he has been involved in a series of heavyweight international arbitrations. He was the lead partner in an ICC arbitration based in Geneva relating to a power and desalination construction project in the Middle East, an SCMA arbitration based in Singapore relating to a dispute arising out of the upgrade of a semi-submersible drilling rig and two LMAA arbitrations based in London relating to delay and cost over-runs arising out of the construction of two semi-submersible rigs in Korea. The sums in dispute in each matter were in the region of US$100 million. In the LMAA arbitrations Will has obtained decisions awarding his clients a total of US$33 million out of total claims of US$34 million, and dismissing the other side’s counterclaims – totalling some US$56 million – in full.
William is also the lead partner acting for a Far Eastern shipyard pursuing claims totalling approximately US$150 million against the buyers of two semi-submersible drilling rigs. In May 2012, his clients obtained summary judgment in the High Court for part of their claim totalling US$57 million. The other side appealed the summary judgment and the matter was recently heard in the Court of Appeal.
Alongside his litigation and arbitration practice, William also assists clients in the drafting and negotiation of various forms of offshore contracts. He has written extensively on marine and offshore construction topics for publications such as Lloyds List, Harts E & P, Petroleum Review and European Oil and Gas, and has lectured on managing litigation risk in high value marine construction projects.
