摘　　要：本文介绍了我国首例海上小规模液化天然气１２００ｍ＾３试验槽船及其配套的ＬＮＧ储存系统船槽采用与船体配合好、且能满足压无损运输要求的圆筒形式储槽；岸上采用结构简单，制造安装方便，具有较高经济性的常压立式储槽；海上平台采用了具有良好抗风流和抗颠簸性能，承压性优，冷损耗低的球形储槽；对工艺流程，设计结构、绝热方式，安全监测及防护系统，汽化及卸货等进行了探讨；分析了当前我国在低温变化，低温储运。China's first LNG test tank ship of 1200 m￣3 and its matching storage system (including 1000m￣3 spherical storage tank on offshore platform and 1000 m￣3 vertical storage tank on coast) are described. The cylindrical and horizontal storage tank matching well with the ship body and being able to meet the transporation needs with pressure without damage, the vertical storage tank with conventional pressure, simple structure, easy making and mounting on coast and the spherical storage tank with anti-jounce, good pressure-bearing and low cold-losing on offshore platform are adopted. The technological process, design texture, adiabatic way, safety monitoring, protection system, gasifying, unloading etc are discussed. The cryogenic liquidation, cryogenic storage and transportation, making technology, the present level and ability of design and manufacture are analysed. The favourable conditions and great potential of developing China's LNG industry are expounded.
