Gasum’s Coralius completes 1,000th LNG bunkering operation

Gasum’s liquefied gas bunkering vessel Coralius has carried out its 1,000th operation, marking a milestone in the company’s efforts to expand low-emission fuel use in shipping.

The operation took place on 23 August at the Port of Kiel in Germany, where the vessel delivered LNG to the cruise ship MSC Euribia. Since entering service in September 2017, Coralius has supplied more than 270,000 metric tons of LNG to vessels of different sizes and segments.

Owned by Anthony Veder and Sirius Shipping and chartered by Gasum, Coralius was the first purpose-built LNG bunker vessel of its kind when it was commissioned. The 1A Ice Class vessel was designed to deliver large volumes of LNG safely and efficiently, and it is powered by LNG engines.

From August 2025, Coralius will switch fully to bio-LNG. According to Gasum, this transition will generate FuelEU Maritime over-compliance that can be made available to shipowners via the company’s pooling service.

LNG and bio-LNG are currently regarded as among the most practical alternative fuels for the maritime sector. Gasum notes that renewable bio-LNG can reduce life-cycle emissions by up to 90 percent compared with marine gas oil.

To meet expected demand growth driven by stricter regulations and customer requirements, Gasum has chartered a new LNG and bio-LNG bunker vessel. Scheduled to enter service in 2027, the vessel will be named Celsius and will feature improved tank insulation, greater cargo capacity and higher fuel efficiency.
