摘要
为研究深水海洋工程船起重工况下的吊索附加动力载荷,选取我国第一艘深水起重铺管船"海洋石油201"作为研究对象,运用三维势流理论以及基于三维面元法的水动力程序分析了船舶的运动响应传递函数,进行了起重工况下运动响应短期预报,推导了吊头运动下的吊物运动方程,计算了载荷传递函数,并利用短期预报公式计算了吊索附加动力载荷短期预报值分析.该研究为起重铺管船的设计提供了参考,并提供了一种适合深水起重船附加动力载荷计算的可行方法.
In order to study additional dynamic load of a lifting rope in a deepwater pipelay crane vessel, the first Chinese deepwater pipelay crane vessel, Haiyangshiyou 201, was used as a case study in this paper. The researchers applied the assumption of 3D potential flow theory and the 3D panel method program to compute motion response re- sponse amplitude operator（RAO） and predict short term response during craning. Motion response equations of lifted objects were derived and load RAOs were carried out. Next, short term prediction value of additional dynamic load was computed using short term prediction formula. The research provides reference to the design of pipelay crane ves-sel, as well as an available method for calculating additional dynamic load suitable for deep water crane vessels.
