Twenty Essex is described as “very user-friendly,” particularly in commercial shipping matters, where its barristers frequently act in high-profile international disputes. A standout case is Angeliki Frangou v John Frangos, where Timothy Hill KC and Andrew Feld are acting against Oliver Caplin KC, who leads Patrick Dunn-Walsh in a dispute between two members of a Greek shipping dynasty concerning loss-pooling arrangements among a group of vessels. In Briety Shipping Inc v Trafigura Maritime Logistics Pte Ltd, a dispute concerning a hire adjustment mechanism after the spike of LNG prices after Russia’s invasion of Ukraine, Michael Ashcroft KC and Daniel Bovensiepen act for the claimant, opposing Philip Edey KC and Michal Hain. Julian Kenny KC and Hain also appeared in the Supreme Court in the litigation concerning the MSC Flaminia, a container ship which exploded in the mid-Atlantic, killing three crew members and causing extensive damage to the vessel and its cargo.
