As a new LNG floating terminal receiver,FSRU has become the global focus in the LNG field because of its own advantages.Based on NFPA standard,this paper designs the fire fighting of a LNG terminal project in a foreign country,and NORSOK standard and domestic fire code are used for reference for the unclear provisions of NFPA standard.This paper introduces the basic configuration requirements of fire fighting system of FSRU jetty, and analyzes the design parameters of jetty cooling water intensity,FSRU cooling water intensity,fire hydrant design flow,escape water mist protection intensity,shore flange supply requirements and fire duration,meanwhile selects reasonable values.The paper gives solutions to the key and difficult problems in engineering design,such as anti corrosion of seawater pipes and fire-fighting facilities,layout of pump house,etc.
