中小型自航绞吸挖泥船经济性评估初探

On economy of small and medium self-propelled cutter suction dredger

随着工业发展,需要拖轮协助作业的非自航绞吸挖泥船越来越难以满足市场需要。为了更好地进行航道疏浚作业,自航绞吸挖泥船的研究不断增多,而目前对自航绞吸挖泥船的研究仅局限于适合广阔水域的大型或超大型船型。我国河流水域众多,对适用于狭窄水域的中小型自航绞吸挖泥船也有一定需求量。因此,文中通过对某中小型自航绞吸挖泥船进行电力推进设计,与相同疏浚能力的非自航绞吸挖泥船对比分析、综合考量后认为,中小型自航绞吸挖泥船具有灵活、环保、便捷、经济等优势。

With the development of industry, non-self-propelled cutter suction dredgers that demands auxiliary operation of tugs become even wore unable to meet the market requirements. However, the primery research at present has been limited among the large or huge ships suitable for wide waters. Since there are many inland rivers in China, it requires small and medium self-propelled cutter suction dredgers which can be applied in the narrow waters. This paper carries out the electric propulsion design of a small and medium self-propelled cutter suction dredger, and analyzes its advantages by comparing it to the non-self-propelled dredger with the same dredging capacity. The results show that the small and medium self-propelled cutter suction dredger has the advantages of flexibility, environmental protection, convenience and economy.
