Russia-Ukraine War 2026- What is Dynagas and how many Yamal LNG vessels does it operate?
- Dynagas is a Greek LNG shipping company that operates six Arc7 ICE-class carriers built for Yamal LNG exports from Russia. Together with Seapeak, it accounts for most of the 11 European-owned vessels in the 15-strong Arc7 fleet.Source: Squire Patton Boggs
- Are Dynagas Yamal ships covered by the EU Russian LNG ban starting April 2026?
- The EU Russian LNG short-term contract ban entered force on 25 April 2026, but the recast text does not explicitly prohibit European-owned Arc7 vessels from continuing to operate. The Arc7 carve-out remains unresolved as of publication.Source: Squire Patton Boggs
- What makes Arc7 vessels different from standard LNG tankers?
- Arc7-class LNG carriers are built to operate in Arctic sea ICE up to 2.1 metres thick, enabling year-round navigation along the Yamal Peninsula export route without icebreaker escort. This specialised rating makes them poorly suited to non-Arctic routes.
Background
Dynagas is a Greek-registered LNG tanker company that operates six Arc7 ICE-class carriers purpose-built for Yamal LNG exports from Russia's Arctic Peninsula. Together with Seapeak Maritime, Dynagas accounts for the majority of the 11 European-owned vessels in the 15-strong Arc7 fleet. The EU Russian LNG short-term contract ban entering force on 25 April 2026 does not explicitly resolve whether European-owned vessels may continue operating on the Yamal route, creating a compliance question that sits with EU insurers and legal counsel rather than with the companies directly.
Dynagas is headquartered in Athens and is closely held. The company has historically operated under long-term charter arrangements with Yamal LNG, the Russian project entity, meaning its Arc7 tonnage is structurally tied to the route by both contract and engineering design: the vessels are Arc7-rated specifically for the Yamal Peninsula sea route and have limited commercial utility outside it.
The ownership concentration of Arctic LNG shipping capacity in two European companies became commercially significant when the Russian LNG ban entered scope discussions in 2025. European ownership of the vessels creates a direct jurisdictional exposure that state-owned or Chinese-flagged tonnage would not carry, making the compliance resolution of the Arc7 carve-out a material item for both companies.
