“防城”号耙吸挖泥船实船功率测试及耙头改造后作业航速预报

Full scale ship power measuring of “Fangcheng” trailing suction hopper dredger and operational sailing speed forecast after draghead transformation

通过“防城号”1500m3耙吸挖泥船实船多工况轴功率测试,对该船作业工况各种阻力成分进行了定量分析,找出各分量之间的比例关系,并对该船改造后的作业技术性能进行了预报。

In order to adapt to the dredging market demand and improve the performance of the dredger, the paper did a feasibility analysis of technical transformation on “Fangcheng” 1 500 m 3 trailing suction hopper dredger, and forecasts the operational technical performance of the dredger after transformation.
