Deadwood Design for a Trailing Suction Hopper Dredger

对于耙吸挖泥船而言,快速性和操纵性直接关系到其航行和疏浚作业的安全性和经济性。呆木作为改善船舶航向稳定性常用的附体,广泛应用于肥大型船上。以某耙吸挖泥船为例,分析呆木对其快速性和操纵性的影响,并介绍呆木的2种线型设计。通过开展阻力和自航模型试验,比较2种呆木线型设计的优劣,供后续同类型船舶的呆木设计参考。

The rapidity and maneuverability directly affect the safety and economy of the trailing suction hopper dredger under navigation and operation. Deadwood, as a common appendage to improve course stability, is widely used on fat vessels. This paper analyses the influence of deadwood on the speed and maneuverability of the trailing suction hopper dredger and introduces two kinds of line design for the deadwood. The advantages and disadvantages of the two designs are compared in the resistance and self-propulsion tests to provide reference for the deadwood design of subsequent ships of the same type.
