Gasum's vessel Coralius has on Saturday 23 August performed her 1000th safe and successful bunkering operation. Coralius is a liquefied gas bunkering vessel and can bunker both liquefied natural gas (LNG) and liquefied biogas (bio-LNG).

The 1000th bunkering took place in the Port of Kiel in Germany and was delivered to the cruise ship MSC Euribia. In its eight years of operation Coralius has delivered more than 270,000 metric tons of LNG to a wide variety of vessels, both large and small.

The Coralius performed her maiden bunkering in September 2017. The vessel is owned by Anthony Veder and Sirius Shipping and chartered by Gasum.

At the time of commissioning, Coralius was the first of its kind, purpose-built LNG bunker vessel. The 1A Ice Classed Coralius was designed specifically to discharge large quantities of LNG to its receiving vessels in a safe and efficient manner.

Lower emissions with LNG and bio-LNG
Coralius itself is powered by LNG-run engines. Compared to other marine fuels, LNG drastically cuts both sulphur oxide (SOx) and nitrogen oxide (NOx) emissions and lowers carbon dioxide (CO2) emissions.

From August 2025 Coralius will run only on bio-LNG. The generated FuelEU Maritime over-compliance will be available to shipowners through Gasum's pooling service.

LNG and bio-LNG are currently the most viable alternative fuels for reducing emissions in the maritime sector. The life cycle emissions of renewable bio-LNG are, on average, 90 per cent lower than traditional fossil fuels such as MGO.

Gasum is committed to increasing the availability of bio-LNG to its maritime customers in the coming years. Demand is expected to intensify as a result of tightening regulations and end-customer requirements.

As part of this commitment Gasum has chartered a new LNG and bio-LNG bunker vessel that will serve Gasum's customers starting 2027. The new vessel, to be named Celsius, will have better fuel efficiency, improved tank insulation and larger cargo capacity.
