LNG耙吸船动力装置的特性分析及发动机选用

摘要

The basic types and features of power units for ships are analyzed with a summary of the types and operation modes of power units for trailing suction hopper dredgers and a comparison of the characteristics of diesel engines, dual fuel engines and full-gas engines. The development trend of gas fueled engines is predicted and discussed according to the technical characteristics of gas fueled engines. Development of LNG-fueled trailing suction hopper dredgers with independent intellectual property rights conforms to the demand of national development, and further improves the operational efficiency and benefits of dredging enterprises.%分析了船用动力装置的基本类型及特点，总结了耙吸船动力装置形式及运行模式，对柴油机、双燃料发动机、纯气体发动机的特性进行了比对，根据气体发动机技术特点展望了气体发动机的发展趋势。研发具有自主知识产权的LNG耙吸船是国家发展的需要，并可进一步提高企业的营运效益。
