摘要
基于珠三角航道疏浚项目中某耙吸式挖泥船的日志数据,从全作业周期的角度分析挖泥船主要能耗的分布特征和变化规律,通过Spearman相关性分析给出船舶航行阶段各能耗影响因子的权重.研究结果显示,航速对船舶能耗的影响最大(权重最高达80％),其次为船舶吃水,水流对船舶能耗的影响最小(权重占比为6％～18％),故节能研究应重点围绕降低船舶航速对能耗的影响.该研究可供后续耙吸式挖泥船节能研究参考.
Abstract
Based on the log data of a trailing suction dredger in the Pearl River Delta waterway dredging project,this paper analyzes the distribution characteristics and variation patterns of the main energy consumption of the dredger from the perspective of the entire operation cycle.Through Spearman correlation analysis,the weights of the energy consumption influencing factors during the navigation phase are given.The research results show that the weight of speed on ship energy consumption is as high as 80％,followed by ship draft,and the weight of water flow on ship energy consumption is 6％～18％.Therefore,energy-saving research should focus on reducing ship navigation energy consumption.This research result can serve as a reference for subsequent energy-saving research on trailing suction dredgers.
