Description

A kind of filling station and charging method of LNG ship
Technical field
The present invention relates to a kind of harbour LNG filling station more particularly to the filling stations and charging method of a kind of LNG ship.
Background technique
Currently, filling interface used in each harbour LNG filling station and LNG filling ship is single integrated mode, It is liquid line and the combination of gaseous state pipeline, i.e. the filling interface of L-V form;It is that gaseous state pipeline and liquid line combine, That is the filling interface of V-L form, this requires LNG liquefied gas carriers filled when filling LNG interface will with the interface of filling station into Row matching, the interfacing order of LNG liquefied gas carrier and filling station, filling ship interfacing order on the contrary, can not then be filled because LNG liquefied gas carrier is global service course line at present, and the filling interfacing order in the area of country variant is not unified, so for The filling interface of LNG liquefied gas carrier can be suitably used for it is different filling interfacing orders connections, particularly with Large LNG filling ship with The docking filling of LNG liquefied gas carrier, since Large LNG filling ship ratio LNG liquefied gas carrier interface position is much higher, LNG Liquefied gas carrier needs a setting high position to fill, and interface is used for and LNG fills ship progress interface docking.
The situation that can not dock such at present is generally there are three types of solution: 1, multiple gaseous states are established on LNG liquefied gas carrier Pipeline and the alternate arrangement of liquid line interface such as liquid filling interface-gaseous state filling interface-liquid filling interface (L-V-L) pipe Road arrangement, liquid filling interface-gaseous state filling interface-gaseous state filling interface-liquid filling interface (L-V-V-L) pipeline arrangement Deng, pass through LNG liquefied gas carrier back-and-forth motion realize filling interface sequence docking;2, since the filling of LNG liquefied gas carrier connects Mouth is arranged symmetrically for port and starboard, passes through hull and rotates 180 ° of sequence docking for realizing filling interfaces;3. fill ship detour 180 ° with The docking of LNG liquefied gas carrier interface, high for the first scheme manufacturing cost, it is more to occupy main deck area, and second and the third side Case is more time-consuming in actual operation, and cost is also relatively high.
