The inland river wharf projects in the middle and upper reaches of the Yangtze River have the characteristics of large water level difference and fast flow velocity.There are currently no operating LNG loading and unloading wharves neither at home nor abroad,and there is no relevant engineering experience for reference.Therefore,in order to promote the development of inland river LNG shipping,it is very necessary to carry out technical research on LNG loading and unloading wharves with large water level difference in inland rivers.This paper analyzes the layout and structural forms of existing coastal LNG(liquefied natural gas) wharves and inland river oil and gas chemical wharves,combined with the characteristics of LNG loading and unloading wharves with large water level difference in inland river.It proposes the plane layout of contiguous wharf and structure scheme of upright wharf with high pile frame,develops a detachable fast cable release hook and a laser rangefinder with automatic lifting guide rail.The appeal schemes that have been applied in practical engineering solve the key technical problems such as multi-boat combination,multi-layer mooring and auxiliary berthing in inland river under the condition of large water level difference,and can provide reference for similar projects.
