Lawyer Rankings

London Bar > Energy

(Leading Silks) Ranked: Tier 1

Lionel Persey QCQuadrant ChambersTremendous gravitas – one of the best cross-examiners of expert witnesses, he will roll up his sleeves as required.

Quadrant Chambers is ‘simply an excellent set, with a number of strong energy practitioners‘. Among its international commercial litigation and arbitration work, energy has been a significant growth area with members handling both upstream and downstream oil and gas matters. Another client comments that ‘the clerks are always helpful and approachable, and they understand client pressures‘. In DSME v Songa Offshore and (now) TransoceanSimon Rainey QC acted for Songa in a dispute concerning the construction of three new state-of-the-art North Sea exploration semi-submersible drilling rigs and allegations of fundamental design failures which made the rigs too heavy and unsuitable for use. Lionel Persey QC continues to be a leading light in the energy space and was recently involved in high-value disputes concerning the supply of vessels to offshore drilling sites, and the cancellation of orders for drilling vessels. Ben Gardner is building his reputation in the energy sector and is currently involved in a high-value dispute concerning a long-term gas supply agreement by a state entity.

London Bar > Shipping

(Leading Silks) Ranked: Tier 1

Lionel Persey QCQuadrant ChambersHe brings an aura that only comes from a top flight silk operating at the very peak of their game.

Quadrant Chambers has the ‘strongest consolidated offering of shipping skills at the London Bar‘ and offers a ‘very wide range of very able counsel and juniors‘, according to clients. The set covers a full spectrum of dry and wet shipping mandates, and houses in-depth expertise across marine insurance, fraud, insolvency, finance and other commercial shipping disputes. The set is regularly involved in Supreme Court cases and landmark case Volcafe v Compania Sud Americana de Vapores, where Simon Rainey QC and David Semark faced John Russell QC and Benjamin Coffer, concerned the correct interpretation of the Hague-Visby Rules as to the burden of proof in cargo claims, was a notable highlight. Lionel Persey QC and Benjamin Coffer appeared in the Court of Appeal for Sea Tank Shipping AS v Vinnlustodin HF (‘The Aqasia’), which is one of the leading cases on Hague Rules and limitation of liability. Classic Maritime v Limbungan Makmur SDN BHD, which examined on the correct application of standard force majeure clauses in long-term shipping contracts of affreightment, was a notable case for Simon Rainey QC and Andrew Leung. Elsewhere, Nigel Cooper QC acted against Michael Nolan QC in Kaefer Aislamientos SA de CV v AMS Drilling Mexico SA de CV, which provides guidance on the approach to take in a dispute over jurisdiction.
