Over many years, we have built a substantial international practice in the energy sector.

We act for energy majors, refineries, shipowners, traders, pipeline operators and offshore companies and have broad experience in the fields of oil, gas and renewables.

Legal services for the energy sector require extensive industry knowledge, a detailed understanding of the law and relevant regulatory frameworks.

We combine market-leading legal analysis with significant in-house expertise. This allows us to apply our know-how to the law and obtain the best results for our clients.

Energy Disputes

Energy disputes are distinctive. They require profound knowledge of the industry, regulatory framework, commercial levers and market developments. Competition and antitrust law often surface in such disputes. We possess this understanding and provide such services to our clients.

This subset of disputes often arises from long-term contractual arrangements and include technically complex fact patterns. Our lawyers have the necessary experience and insights to fully grasp the complexity underlying energy disputes. We work tirelessly to ensure the best possible outcome for our clients, in arbitration, litigation and related negotiations.

Our broad experience ranges from Central and Eastern European gas transit, storage and supply to Caspian mining; as well as from the construction of hydroelectric power stations in Central Europe to investments and joint ventures in coal-fired power plants in Eastern Europe, a corporate dispute in a major oil and gas company in Ukraine, a vessel breakdown with major delay losses, and countless energy-related contract disputes, as discussed below.

We frequently act on price adjustment disputes or disputes based on the premature termination or amendment of long-term contracts.

Liquified Natural Gas

Our LNG team, led by Damon Thompson, who worked in-house at a major energy company for eight years, has a keen focus on this specific energy product.

We are routinely instructed on both advisory and contentious work in the LNG market. Our clients include shipowners, charterers and major oil companies. We have significant experience litigating the industry standard charterparty forms, including ShellLNGTime 1 and ShellLNGTime 2.

Additionally, as the LNG market continues to grow, we regularly deliver presentations and LNG specific training to industry leaders and new market participants on these standard charterparty forms and the potential issues they present.

A major Singapore LNG trader provided this recent testimonial:

“We engage Damon Thompson regularly as our legal advisor and consultant on shipping and other commercial matters.  His specialist knowledge and passion in LNG shipping is well-known, but that is only half the story.  Shipping is one of the main components of a commercial transaction, and I trust in Damon’s understanding of each and every component of originating, negotiating and closing the deal.  I can rely on him to properly assess the risks and address what is necessary in order to bring a deal across the line.  This knowledge is acquired from his time in-house before returning the private practice, as well as his extensive networks in the shipping, LNG and insurance industries.  We highly recommend him as a trusted advisor in this area of law.”

Oil & Gas

We act for market participants across the oil and gas industry, whether it is in supply, trading, refining, transport, transit, shipping, storage or construction. Our expertise covers advisory work and disputes relating to oil and gas construction projects, tanker charterparty disputes, and sale and purchase or supply agreements, gas transit agreements and gas storage agreements, among many other contracts.

The market dynamics that underpin our clients’ business practices and their motivations are critical in any dispute. In the oil and gas sector, ongoing business relationships often mean that early negotiation between parties is customary and can be the first step to a satisfactory resolution. Where that fails, we have decades of experience successfully pursuing claims in arbitration and litigation.

The monetary values involved in this trade are typically considerable. Clients come to us for our trusted reputation, close attention to detail and dedication to the matter at hand.

Exxon was successful in voiding a US$2 million sanctions penalty. However, for the rest of us this case demonstrates why caution around sanctions remains of paramount importance.
