全球LNG船运市场及运输船技术发展分析

介绍全球LNG海运现状,对LNG运输船关键技术进行分析。随着LNG需求及贸易的不断增长,全球LNG贸易商对LNG运输船需求将明显增长,LNG运输船容积向大型化发展。LNG运输船推进系统是制约其发展的关键技术之一,节省燃料、高效、可回收BOG的推进系统,是未来发展的方向。LNG运输船液货舱主要以薄膜型、独立球型液舱储罐为主,薄膜型液舱储罐性能更优,造价低,受到船东青睐。

Analysis of Global LNG Shipping Market and Carrier Technology Development

The current status of global LNG maritime transport is introduced,and the key technologies of LNG carriers are analyzed. With the continuous growth of LNG demand and trade,global LNG traders’ demand for LNG carriers will also increase significantly. and the capacity of LNG carriers is also developing towards large scale. The propulsion system of LNG carrier is one of the key technologies restricting its development. Fuel-saving, efficient and recyclable BOG propulsion system will be the direction of future development. The cargo tanks of LNG carriers are mainly membrane-type and independent spherical tanks. The membrane-type tanks have better performance and lower cost,which are favored by ship owners.
