随着液化天然气(LNG)动力船舶的增多，为其加注LNG燃料的技术、方法、设施和设备已成为造船业和航运业面临的一个突出问题.LNG加注船因具有自航能力、安全可靠、调度灵活等优点而成为LNG加注技术的重要发展方向.在结合近年来对LNG加注船方案设计所做的研究和相关方面专家的建议，并总结LNG加注船作业特点的基础上，建立了一套针对LNG加注船的方案评价指标体系，对其评价方法进行了研究，并在该评价指标体系的基础上，采用改进的模糊层次分析法对设计方案进行优选.分析和计算实例表明，该评价指标体系和评价方法是适用和可靠的.
With the increase of the ship that uses liquified natural gas (LNG) as main fuel, the technology, methods, facilities and equipment for the filling of LNG fuel have been a prominent issue in shipbuilding and shipping industry. LNG bunker vessel is an important development direction of LNG offshore filling technology because of its advantages of self-navigation ability, safety and reliability, flexible scheduling and so on. Considering the research work of the design of the LNG bunker vessel and experts advice in recent years, a set of evaluation index system for LNG bunker vessel is established and its evaluation method is studied. On the basis of establishing the evaluation index system, the optimization of design scheme is made by using the improved fuzzy analytic hierarchy process. Preliminary analysis and calculation examples show that the evaluation index system and evaluation method are applicable and reliable.
