UK sanctions on Russian LNG have opened a new front for George Prokopiou’s group. From 1 January 2027, the rules on insurance cover and maritime services will change, creating risks for the operation of vessels serving the Yamal LNG project, as well as for the debt obligations of Dynagas LNG Partners.
At the centre of the issue are two LNG carriers owned by Dynagas LNG Partners, whose interests are controlled by G. Prokopiou: the Yenisei River and the Lena River. Each has a carrying capacity of 155,000 cubic metres. Built in 2013, both are employed under long-term charters on the Russian Yamal LNG project.
Their importance to New York-listed Dynagas is considerable. According to the company’s financial statements, the two vessels accounted for 36% of its cash revenues in the first half of 2026. Their charter contracts run until 2033 and 2034, respectively, with options for further extensions.
The risk to charters and loans
The UK’s new sanctions regime, introduced in May 2026, prohibits UK persons from providing or facilitating maritime transport services for Russian-origin LNG, even when the cargo is destined for third countries. From 1 January 2027, the ban will also cover certain long-term contracts entered into before 17 June 2025.
For Dynagas, the first immediate consequence is the need to replace some of its key counterparties, including insurers and UK-based maritime service providers, with equivalent providers outside UK jurisdiction. The company itself has acknowledged the need for these changes in its latest updates to regulators.
However, the issue goes beyond the cost of replacing insurers and other counterparties. The bigger question is whether the existing charters for the two vessels can continue without disruption. If the new restrictions make it more difficult or costly to provide the necessary services, the company could face operational disruptions, higher costs and possible periods when the vessels are idle.
There is also a contractual dimension. Dynagas believes its long-term contracts with Yamal remain binding despite the new sanctions. It acknowledges, however, that there is no certainty the charterer will share that interpretation. Any such disagreement could lead to a breach of obligations, legal disputes or even early termination of the contracts.
The effects could also extend to the company’s finances. The loss of, or a significant decline in, revenue from the two charters would reduce its cash flows, potentially making it harder to meet its debt obligations and comply with its loan covenants. This risk is particularly significant given Yamal’s large contribution to Dynagas’ revenues.
The European dimension
The picture is further complicated by European sanctions. The EU’s 19th package of measures provides for a ban on imports of Russian LNG under long-term contracts from 1 January 2027. Dynagas believes that shipments of Yamal cargoes to destinations outside the EU can fall under the exemption for legacy contracts (Legacy Contract Derogation). It cautions, however, that there is no guarantee the relevant authorities will accept its interpretation or that all the conditions for the exemption will continue to be met.
As a result, 1 January 2027 is becoming a critical milestone for George Prokopiou’s group. The stakes go beyond reorganising its network of insurance and maritime service providers: they include preserving a significant source of revenue, ensuring the smooth performance of long-term charters and protecting the company’s financial position.
