Vessel mooring analysis and ignition range dispersion analysis for LNG jetty facilities

The LNG jetty is facilities (forming part of the terminal) for the berthing and unloading of LNGC, including all shore-side discharging arms and docking facilities.The criteria design to build new LNG based on some aspect such as the result of bathymetric survey, the tanker or other vessel, port facilities, mooring layout, and also catastrophic accident such as LNG vapor dispersion. One of the critical issue on the LNG Jetty design is the configuration of mooring vessel, that should be analyzed before vessel need to berth on jetty. Mooring are provided to prevent vessel from drifting away from a berth. It is assumed that the wave motions are unaffected by the stiffness of the mooring lines and fenders.
