20000cbm LNG 运输加注船是全球主流、由中国主导设计建造的中小型 LNG 多功能船型，兼具运输与船对船加注能力。该型船总长约160米、型宽25米、设计航速15.5节，货舱容积20000立方米，采用C型独立液罐，日蒸发率低至0.16%。主机多为WinGD iCER双燃料机，满足IMO Tier III排放，可选高压岸电，低碳环保。加注速率可达2000立方米 / 小时，可服务大型LNG动力船，兼具海上浮式储存功能。主要由中集太平洋海工等中国船厂批量建造，是全球LNG燃料加注与绿色航运转型的核心装备。

The 20,000 cbm LNG transport and bunkering vessel is a globally prevalent medium-to-small multifunctional LNG ship type independently designed and built under Chinese leadership, equipped with both cargo transportation and ship-to-ship bunkering capabilities.

The vessel has an overall length of around 160 meters, a moulded breadth of 25 meters, and a design speed of 15.5 knots. Its cargo tank capacity stands at 20,000 cubic metres, fitted with independent Type C liquid tanks delivering an ultra-low daily boil-off rate of only 0.16%.

Main engines are mostly WinGD iCER dual-fuel engines that comply with IMO Tier III emission standards. High-voltage shore power is available as an option for low-carbon and eco-friendly operation.

It achieves a maximum bunkering rate of 2,000 cubic metres per hour, capable of servicing large LNG-powered vessels, and also features offshore floating storage capacity.

Mass-produced primarily by Chinese shipyards including CIMC Pacific Offshore Engineering, this vessel constitutes core equipment for global LNG fuel bunkering and the transition to green shipping.
