摘　　要：以LNG双燃料Suezmax原油船为对象,研究其总体设计关键技术。阐述了首尾线型的设计特点和节能装置的应用比较,以及空船重量控制和结构设计满足最新规范的优化。分析了LNG C型罐在主甲板上的布置位置引起的视线盲区问题,并提出解决方案。在不同的风向、风速和船速等组合场景下,应用CFD方法数值模拟了LNG蒸气云团扩散对甲板面、生活楼和烟囱的影响,确定透气桅的较佳布置位置。综合多方面因素,对比分析双壁燃气管路在机舱的布置方案,收到了降本增效的效果。This paper studies several key technologies in the general design of LNG dual-fuel Suezmax crude oil tankers.Design features of the fore-body and aft hull lines,energy-saving devices,and comparison between them,as well as control of lightweight and optimization of the structural design for meeting the latest rules,are described.Blind sectors caused by the layout ofLNG C-type tanks on the main deck are analyzed,and a solution is put forward.With the aid of CFD numerical calculation,the possible impact of diffusion of the LNG vapor cloud on the deck,living building,and chimney are evaluated under different wind directions,wind speed,and ship speed,and a better layout of the LNG vent mast is determined.The arrangement scheme of double-walled fuel gas pipes in the engine room is analyzed,which effect of cost reduction and efficiency increase is achieved.
