Denton Wilde Sapte has scooped the lead role advising Allseas in one of the largest arbitrations in history.
The new instruction follows the departure of the claimant's previous lawyers at Mayer Brown Rowe & Maw to the London office of US firm Hunton & Williams.
Dentons partner Philip Chong, who previously had a minor role for the claimant, has assumed full control for leading Allseas' action, which is now proceeding to quantum.
Allseas won its case against Sembawang Shipyard in Singapore in relation to the quality of its work on the conversion of a bulk carrier, Solitaire, into a pipelaying vessel in March.
Chong is now preparing the quantum case, due to start in January 2004.
Allseas is claiming some $400m (£250.3m) relating to the costs involved in transferring Solitaire from a Sembawang shipyard in Singapore to the UK for the conversion to be completed. It also relates to costs stemming from delay and defective work done by Sembawang, which has a $90m (£56.3m) counter-claim set down for four months in February 2005.
The six-year arbitration finally ended in March last year after lawyers trawled through some two million documents and 24,000 drawings. The case was severely disrupted by first the resignation of the arbitration chairman Donald Davis, and subsequently by the death of arbitrator Michael Ferryman.
Partners Marie Kidwell and John Miles, who were leading the case during this period, joined Mayer Brown from Dentons during a hearing that led to the ninth and final award. Having now moved to Huntons, their client decided to transfer the whole matter solely to Chong.
