Enagas said in a statement on Thursday that it has signed, through its unit Scale Green Energy, an agreement with Naturgy for the construction and chartering of the LNG bunkering vessel, to be named Mistral LNG.
Scale Green Energy, which launched construction of the vessel in early 2026, will operate the vessel.
The vessel is expected to start serving Naturgy in 2028 under a long-term contract, according to Enagas.
Enagas did not say who would build the LNG bunkering vessel.
LNG Prime contacted Enagas to provide further information on the vessel’s construction, and we will update this article if we receive a response.
Enagas’s unit currently has one 12,800-cbm LNG bunkering vessel under construction at China’s CIMC SOE.

The ship will be 138.8 meters long, it will have a dual-fuel engine, a service speed of 13 knots, and a range of over 4,500 nautical miles.
Designed to supply LNG and bio-LNG, the vessel will be equipped with advanced technology to minimize emissions and optimize efficiency, Enagas said.
Iberian Peninsula and other locations
Following delivery, Mistral LNG will operate mainly in the Iberian Peninsula, which is strengthening its position as a strategic hub in southern Europe for bunkering, as well as in the Strait of Gibraltar and the Canary Islands, among other destinations in the Atlantic, it said.
With this initiative, Naturgy is positioning itself as a strategic operator in the Iberian LNG and bio-LNG bunkering market, which is expected to grow exponentially in the coming years, Enagas noted.
On the other hand, Enagas, via its unit Scale Green Energy, is consolidating its position as a shipowner in LNG bunkering in southern Europe by adding this new vessel to its current fleet of three ships: Levante LNG, Alisios LNG, and Haugesund Knutsen, the company said.
Enagas noted that the seven Spanish regasification plants are already adapted to supply LNG for bunkering, and that the plants in Barcelona, Cartagena, Huelva, and Gijon have launched bio-LNG supply services for ships and trucks.
The firm has three wholly-owned LNG import plants in Barcelona, Huelva, and Cartagena.
In addition to these three plants, Enagas owns 75 percent of the Musel LNG facility, 50 percent of the BBG regasification plant in Bilbao, and 72.5 percent of the Sagunto plant, while Reganosa operates the Mugardos plant.
