The company operates 27 gas carriers, a significant portion of which are specialized Arc7-class icebreaking tankers. Such vessels are used for operations in the Arctic and to serve the Russian Yamal LNG project.

According to Financial Times estimates, since the beginning of 2025, Dynagas has transported over 10 million metric tons of Russian liquefied natural gas across 11 vessels, completing 144 voyages.

The Greek side claims that it is virtually impossible to redeploy Arc7-class specialized vessels to other routes. If sanctions are imposed, the company may be forced to sell them to buyers outside the West. The cost of a single such tanker is estimated at approximately $300 million.

If the gas infrastructure that they service gets hit the way the oil infrastructure has and the ships have nothing to transport, Dynagas might regret not having sold the ships off prior to that evaporation of demand.

Prior sanctions will have allowed a (relatively) ordered exit for European consumers, before Russia stopped exporting gasoline and diesel due to infrastructure damage, prioritizing what remained for itself.

If you own an expensive ship that can't be used on any other route, you may not want to be sitting on it if that route becomes non-viable.
