据天然气加工和液化天然气2021年7月23日报道，俄罗斯一名高官7月23日表示，俄罗斯计划建造第一批以液化天然气（LNG）为动力的破冰船，这让此前搁置的想法重新提上了议事日程。
俄罗斯拥有世界上唯一的一支核动力破冰船队。 由于气候变化导致冰层融化，俄罗斯将建造这支以LNG为动力的破冰船队，希望将穿过其北侧的北冰洋航线发展成一条国际航线。
俄罗斯国家原子能公司（Rosatom）首席执行官阿列克谢·利哈乔夫告诉记者：“我们现在回到了这个建造以LNG为动力破冰船的话题。 我认为，到今年年底前，我们将决定建造两到四艘中型以LNG为动力破冰船的可能性。 ”
俄罗斯政府日前已指定这家国有原子能公司为北冰洋航线的国有运营商。
俄罗斯第2大天然气生产商诺瓦泰克在2018年与俄罗斯国家原子能公司签署了一项谅解协议，共同开发以LNG为动力的破冰船。 但这些计划后来都不了了之。 诺瓦泰克在北极地区有几个LNG项目。
与建造核动力破冰船所需的600亿卢布(8.14亿美元)相比，以LNG为动力破冰船的建造成本只有前者的一半。
利哈乔夫的代表基利尔·科马罗夫说，俄罗斯国家原子能公司还订购了另外两艘项目名称为22220的核动力破冰船。
俄罗斯去年建造的最新破冰船《北极号》是该系列项目的第一艘。 另外四艘目前正在开发中。
俄罗斯政府希望今年通过北冰洋航线运输的碳氢化合物和其他资源的货运量从去年的3300万吨增加到8000万吨。

Russia to build first LNG-powered icebreakers for Arctic sea route
Russia plans to build its first batch of icebreakers that are powered by LNG, a top official said on Friday, returning to an idea that was put on hold.
Russia has the world's only fleet of nuclear-powered icebreakers. It is building up that fleet, hoping to develop the Northern Sea Route across its northern flank into an international shipping lane as climate change melts the ice.
"We are now returning to this topic (building LNG,-powered icebreakers). I think that by the end of the year we will decide on the possible construction of two to four medium-sized icebreakers," Rosatom chief Alexei Likhachev told reporters.
Russia's government has named state nuclear energy firm Rosatom as the Northern Sea Route's state operator.
Gas producer Novatek signed an agreement of understanding with Rosatom to develop LNG-powered icebreakers in 2018. But those plans went quiet. Novatek has several LNG, projects in the Arctic.
LNG-powered icebreakers cost half the 60 billion roubles ($814 million) needed to build nuclear-powered icebreakers.
Likhachev's deputy Kirill Komarov said Rosatom had also ordered another two nuclear-powered icebreakers known by their project name 22220.
Arktika, Russia's newest icebreaker that was built last year, was the first of that project series. Another four are currently in development.
The Kremlin wants to increase the amount of cargo transported through the NSR to 80 million tonnes from 33 million tonnes last year by shipping hydrocarbons and other resources produced in the Arctic.
