        北欧能源公司Gasum的液化天然气（LNG）双燃料供应船“Kairos”号自 2022 年 10 月起由其他公司船队租赁使用，而现已回归Gasum公司自己的燃料加注船队。

        “Kairos”号运载能力为7,500立方米，配备以液化天然气为主要燃料的双燃料发动机，并在设备技术上颇具特色。

        该船设计用途是使其能在欧洲西北部所有可加气点，向各类大小不一的船舶加注液化天然气。这艘船舶每小时的液化天然气输送量介于60立方米到1,250立方米之间。

        此外，“Kairos”号的起重机射程可达30米。同时，该船已通过船舶“DP2”系统认证，并按照船舶1A级冰区标准建造，因此其能在恶劣天气和公海上进行作业。

        据Gasum公司称，2023年期间，公司在液化天然气海上加注领域业务量目前处于稳步增长状态，预计年底将进一步加快其发展步伐。

        从传统船用燃料改用液化天然气意味着船舶排放的污染物中将完全消除SOx类气体及微粒污染物，能够大大减少85%的NOx类气体排放量，并且也会减少约20%的二氧化碳排放量。此外，液化天然气与可再生液化沼气（即bio-LNG或LBG）能够互换，也就意味着这两种气体可以任意比例进行混合。

        与传统化石燃料相比，Gasum公司的生物天然气预计平均可减少90%的碳排放量。该公司强调，航运业向低碳未来迈进的具体行动之一便是增加生物液化天然气的使用。

        该公司解释补充说：“Gasum公司战略目标便是，截至2027 年，其每年能向市场提供7太瓦时（TWh）的可再生天然气。这一目标的实现也意味着每年将为其客户减少累计180万吨的二氧化碳排放量。”

        上个月，该能源公司在冰岛的Reykjavik港口进行了首次液化天然气加注作业。 液化天然气加注船“Coral Energy”号向PONANT公司的破冰游轮“Le Commandant Charcot”供给了液化天然气和液化沼气（LBG）。

Gasum’s dual-fuel LNG bunker vessel Kairos returns to fleet

Gasum’s liquefied natural gas (LNG) bunker supply vessel Kairos has been sub-leased outside the company since October 2022, but has now returned to Gasum’s own bunkering fleet. 

Kairos has a capacity of 7,500 cbm and is equipped with a dual-fuel engine using LNG as main fuel and is equipped with a range of technical features.

The ship has been designed to supply LNG to various types and sizes of vessels at all possible bunkering locations in Northwest Europe. The vessel can supply LNG with a transfer rate from 60 cbm per hour up to 1,250 cbm per hour.

Additionally, the vessel’s cranes have a range of up to 30 meters. Kairos is able to operate under harsh weather conditions and at high sea, due to the vessel being DP2 certified and built to ice class 1A.

Volume growth in the maritime LNG bunkering segment has been gathering speed steadily during 2023 and is expected to further pick up pace towards the end of the year, according to Gasum.

Switching to LNG from traditional maritime fuels means complete removal of SOx and particles, and a reduction of NOx emissions of up to 85 percent. LNG reduces CO2 emissions by approximately 20 percent. LNG is interchangeable with renewable liquefied biogas (bio-LNG or LBG), which means that the two gases can be mixed at any ratio.

Gasum’s biogas is expected to cut carbon emissions on average by 90 percent when compared with traditional fossil fuels. Increasing the use of bio-LNG is one of the concrete actions that will take the shipping industry towards a low-carbon future, the company emphasized. 

“Gasum’s strategic goal is to bring seven terawatt hours (7 TWh) of renewable gas yearly to market by 2027. Achieving this goal would mean a yearly cumulative carbon dioxide reduction of 1.8 million tons for Gasum’s customers,” the firm explained.

Last month, the energy company carried out the first LNG bunkering operation in the port of Reykjavik, Iceland.  LNG bunker vessel Coral Energy delivered LNG and liquefied biogas (LBG) to PONANT’s ice-breaking cruise vessel Le Commandant Charcot.
