The invention discloses a skid-mounted external transportation system for small FLNG and an operation method thereof.The skid-mounted external transportation system comprises LNG connector enclasping devices, two LNG ship bodies and an external transportation ship body, external transportation ship deck anchor gears are arranged on the external transportation ship body, the LNG connector enclasping devices are installed on the two sides of the stern of the FLNG ship body respectively, LNG cabins are arranged on the two LNG ship bodies respectively, and the LNG cabins are connected with the external transportation ship deck anchor gears. A mooring mooring bollard is arranged on a deck of a bow of the LNG ship body, an LNG receiving end is further arranged on a clamping plate of the bow of the LNG ship body, and a mooring assembly used for being matched with the mooring mooring bollard to mooring the LNG ship body is arranged on the LNG connector enclasping device. Compared with an existing FLNG external transportation system, the system has the external transportation function and the LNG storage function at the same time, and therefore only connection and disconnection operation between the external transportation system and the FLNG and between the external transportation system and a transport ship needs to be carried out in the external transportation process, the LNG external transportation process is omitted, and the external transportation operation timeliness is improved.
本发明公开了一种针对小型FLNG的撬装化外输系统及其作业方法,包括LNG接头抱紧装置、两个LNG船体和外输船船体,所述外输船船体上设有外输船甲板锚机,所述LNG接头抱紧装置分别安装在FLNG船体船尾两侧的位置,两个所述LNG船体上均设有LNG舱,所述LNG船体船头甲板上设有系泊带缆桩,所述LNG船体船头夹板上还设有LNG接收端,所述LNG接头抱紧装置上设有用于与系泊带缆桩配合对LNG船体进行系泊的系泊组件;本发明与现有FLNG外输系统相比,该系统同时具备外输和LNG储存功能,因而在外输过程中只需要进行外输系统与FLNG及运输船之间的连接与解脱作业,省去了LNG外输过程,提升了外输作业时效。
