摘要
长江中上游等内河码头工程,具有水位差大、水流流速快的特点。国内外暂无已经运营的内河LNG接卸码头,无相关工程经验可以借鉴。因此,为推动内河LNG航运的发展,开展内河大水位差LNG接卸码头的技术研究十分必要。通过对已有沿海LNG(液化天然气,liquefied natural gas)码头、内河油气化工码头的布置及结构形式等进行分析,结合内河大水位差LNG接卸码头的特点,提出连片式码头平面布置方式和高桩框架直立式码头结构方案,研制一种可拆卸式快速脱缆钩和自动升降导轨式激光测距仪,并将相关技术应用于实际工程,解决了大水位差条件下内河多船型组合、多层系缆以及辅助靠泊等关键技术问题,可为类似工程提供参考。
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.
