摘要
“三缆定位”为绞吸式挖泥船的定位方式之一,比起“钢桩定位”方式,它更适合大挖深、大风浪等恶劣工况,但其原理上更复杂,对技术要求更高。“三缆定位”主要通过绞吸式挖泥船尾部的三根定位钢缆来给船舶定位。众所周知,绞吸挖泥船的施工精度,主要由船舶的定位精度来决定,所以,一个准确高效的“三缆定位”算法将是系统设计的核心。通过对“三缆定位”控制原理及过程的描述,最终实现了绞吸式挖泥船的“三缆定位”。
“Christmas Tree” is one of the methods of positioning cutter suction dredger, which is , compared with ＂spud positioning＂, more suitable for the unfavorable conditions like deep water and strong waves. But it is more complicated in principle and has higher technical requirements. ＂Christmas Tree＂ positions ships with three anchor wires on the stem of cutter suction dredger. As is known to all, the working accuracy of a cutter suction dredger depends on the accuracy of positioning, therefore, an accurate and effective ＂Christmas Tree＂ algorithm is the core of the design. Through research into the principle and procedure of ＂ Christmas Tree＂, this paper illustrates how to design and apply it for the cutter suction dredgers.
