Gemma is regularly instructed on s.44 applications to the Court for interim relief and s.68 and s.69 appeals.

Examples of ongoing and recent instructions include:

• Gemma acts as junior counsel (to Chirag Karia Q.C.) for a major Chinese oil importer and producer in relation to a series of claims, both in the High Court and LCIA arbitration, arising out of delivery of off-spec oil cargoes under a series of sales contracts.

The claim also involved ancillary enforcement proceedings in multiple jurisdictions, predominantly Dubai, and the obtaining of world-wide freezing and disclosure orders in the Commercial Court.  Gemma was led by Poonam Melwani Q.C.

Gemma is frequently instructed in technically demanding, complex energy and offshore work, both as sole and junior counsel. Gemma has acted this year in two major commercial disputes in the oil and gas sector. Gemma is regularly instructed to act for and to advise clients both in respect of technical disputes and in claims arising out of issues of contractual construction and recoverability of sums paid under terminated contracts. She has extensive experience of drafting detailed pleadings in complex cases as well as advising in relation to a full spectrum of legal and technical issues arising out of energy and offshore contracts.

Current and recent notable cases that Gemma is or has been instructed on include:

• Seadrill Ghana Ltd v Tullow Ghana Ltd [2018] EWHC 1640 (Comm) (instructed by Haynes Boone CDG). 3 week Commercial Court trial. The owner of the semi-submersible drilling rig “WEST LEO” claimed $250 million from the Defendant arising out of the operation of a long-term contract for the use of an ultra-deep water semi-submersible rig offshore Ghana. Extensive evidence was heard in the case dealing with (i) Tullow’s JOA arrangements with its JV partners, including issues of authorisation to drill, liabilities for costs incurred for mutual benefit and whether or not adequate consents had been obtained by Tullow as operator for work done on behalf of the JV; and (ii) the technical requirements for drilling five wells together with the feasibility and necessity of drilling those wells. Gemma acted for the successful Claimant, Seadrill.
• Acting as junior counsel (to Simon Rainey Q.C.) for a claimant oil major in a complex claim arising out of the operation and contractual construction of a Unit Agreement which governs the parties’ rights and obligations in respect of the joint development of a major oilfield, located offshore Nigeria. Two OPLs traverse the oilfield and the respective shares of cost and revenue between thein each of those OPLs is in dispute. The claim is worth approximately US$ 2 billion. Gemma appeared as junior counsel at a 5-day LCIA arbitration hearing in June 2015 and is instructed to appear in the second phase of the arbitration in Lagos in December 2017. Gemma also advises the Claim.
• Instructed as junior counsel (to Simon Rainey Q.C.) for the Claimant in Commercial Court litigation Talisman Sinopec Energy UK Limited, Baker Hughes Limited [2015]. The claim was for damages for breach of contract, misrepresentation and restitutionary remedies arising out of a contract for the design, manufacture, supply and install a number of Electrical Submersible Pumps and the provision of ancillary services to a number of oil fields in the North Sea. The Claim was for a sum in excess of £230 million and gave rise to complex, technical engineering issues as well as complicated damages calculations for loss of profit and use claims arising out of a loss of production in the affected wells. The dispute also turned upon the effectiveness of a contractual exclusion upon recovery for loss of profit and consequential loss. The case has recently settled. 
• Acting as sole counsel for the claimant North Sea oilfield operator to advise in respect of recovery of sums due under a Lease and Use Agreement relating to the lease of a number of assets and licences in a North Sea oilfield.

• Instructed for the buyer against a South Korean shipyard in respect of a US$500 million complex arbitration dispute arising out of the construction of a specialist offshore semi-submersible oil drilling unit and cancellation of the construction contract. The buyer cancelled the contract following late delivery and the yard now claimed in respect of alleged losses arising out of the same. The case involved highly technical engineering issues as well as complex legal issues concerning the recoverability of payments made by the buyer prior to cancellation. Gemma was led by Lionel Persey Q.C. of Quadrant Chambers together with two other junior counsel. 
• Acts as sole counsel for the claimant owners of two off-shore vessels in two, concurrent arbitrations concerning claims against the respondent Charterers for unpaid hire worth about US$8.5 million arising in relation to offshore oil exploration in Nigeria. Charterers’ counterclaims raise technical issues of breach of charterparty arising out of alleged breaches of warranty of description. The case raises a novel contractual damages point about the cross-recoverability of losses suffered under related but distinct contracts. Gemma is also instructed to advise Owners on various interlocutory matters, including the enforcement of several partial arbitration awards in multiple jurisdictions.
• Acted as junior counsel (to Lionel Persey Q.C. and Michael Davey Q.C.) for the successful Claimant buyers in an arbitration claim for US$40 million concerning the construction of two offshore supply vessels and repudiatory breach due to late delivery.

Examples of Gemma's recent and current instructions in this area include:
