由于LNG船需要在众多液化天然气码头进行交易，因此系泊系统与码头的兼容性是此类船舶总布置的关键点之一。本文介绍了系泊系统的主要兼容项目，阐述了系泊系统设计的关键因素，包括系泊布置、系泊计算、环境组合、设计标准等，分析了3种典型的系泊兼容案例。案例 A 基于系泊至码头和标准 OCIMF（Oil Companies International Marine Forum）环境；案例 B 基于系泊至码头、标准 OCIMF 环境以及码头要求的当地环境；案例 C 基于系泊至浮式储存再气化装置（船对船）和标准 OCIMF 环境。可以看出，对于特定的码头，系泊分析所选环境除了标准 OCIMF 环境外，还应基于码头的要求。当考虑波浪时，标准 OCIMF 环境中的风速必须降低，以满足OCIMF衡准要求。对于船对船系泊，系泊至码头和船对船的系泊缆绳均可通过降低风速来遵循 OCIMF 限制。这些发现有利于LNG船系泊系统的兼容性。
As Large LNG Carrier has to trade in many LNG terminals, mooring system compatibility with terminals is one of key points in general layout of such vessels. Main compatibility items of mooring system is presented.Key factors of mooring system design are introduced, including mooring arrangement,mooring calculation,environment combination,design criteria,etc. Three typical mooring compatibility cases are analyzed:Case A based on mooring to terminal and standard OCIMF environment;Case B based on mooring to terminal, standard OCIMF environment and local environment required by terminal;Case C based on mooring to FSRU (ship-to-ship) and standard OCIMF environment.It can be seen that for certain terminal,the selected environment for mooring analysis shall be based on terminal requirement in additional to standard OCIMF environment.When wave shall be considered, wind speed of standard OCIMF environment has to be reduced in order to meet OCIMF 50%-line load limit.For ship-to-ship mooring, mooring lines for both mooring to terminal and ship-to-ship can follow OCIMF limits by lowering wind speed. These findings are helpful for mooring system compatibility of Large LNG Carrier.
