现代耙吸挖泥船节能减排技术的发展与应用

耙吸挖泥船是高能耗的施工船舶,研究和应用节能减排技术降低能耗,不仅可以为疏浚企业节省燃油费用,还可以减少船舶造成的环境污染,获得经济和环保双重效益。介绍挖泥船节能减排的含义和评价指标,从船型设计、推进动力系统优化、疏浚机械和集成监控系统开发及设计建造单耙挖泥船等方面讨论耙吸挖泥船节能减排技术的发展及应用现状。

Development and application of energy-saving technology for modern trailing suction dredgers

The trailing suction hopper dredger is such a kind of construction ships with high energy consumption. By the study and application of energy-saving technology, not only the fuel costs could be saved, also the environmental pollution caused by ships could be reduced, therefore both economic and environmental benefit could be achieved. By introducing the definition of energy conservation and evaluation of the trailing suction hopper dredger, this paper discusses the energy-saving technology and present application status of ship design, power equipment, the development of dredging machinery and integrated monitoring system, and construction of single suction pipe dredgers.
