摘　　要：耙吸挖泥船是一种复杂的吸扬式挖泥装备,是疏浚行业的主导船型,而LNG双燃料耙吸挖泥船又为疏浚市场注入新的活力。文章介绍了国内外LNG双燃料耙吸挖泥船的发展现状,通过对目前国内外LNG双燃料耙吸挖泥船的现行调研分析对比,归纳了LNG双燃料耙吸挖泥船在船型及主尺度作业方式及主要性能的技术特点;初步探讨了LNG双燃料耙吸挖泥船的4个发展方向。然后推出了一款可用于沿海港口、航道的疏浚、吹填工程的8 000 m3LNG双燃料耙吸挖泥船设计方案,研究了船舶主要技术参数、动力装置及挖泥性能。最后对未来LNG双燃料耙吸挖泥船的发展进行了展望。Trailing suction dredger is a complex suction dredging equipment and the leading ship type in the dredging industry. LNG dual fuel trailing suction dredger injects new vitality into the dredging market. the development status of LNG dual fuel trailing suction dredgers at home and abroad is introduced. Through the current investigation, analysis and comparison of LNG dual fuel trailing suction dredgers at home and abroad,the technical characteristics of LNG dual fuel trailing suction dredgers in ship type, main scale operation mode and main performance are summarized. Four development directions of LNG dual fuel trailing suction dredger are discussed. Then, the design scheme of an 8000m~3 LNG dual fuel trailing suction dredger which can be used in the dredging and reclamation of coastal ports and waterways is introduced. The main technical parameters,power plant and dredging performance of the ship are studied. Finally, the future development of LNG dual fuel trailing suction dredger is prospected.
