以第20届国际拖曳水池会议ITTC推荐的计算互比模型为例，开展缩尺比为1∶[KG-*2]70的半潜式海洋平台在不同浪向角下运动响应的试验，研究海洋平台运动的试验方法，探索模型试验测量技术，校核和检验深水海洋工程测量系统的有效性. 结果表明：试验结果与数值模拟结果以及ITTC所公布的数据基本吻合.
Abstract
This paper presented the results of modal test of an offshore semisubmersible drilling platform conducted in the wave tank in Harbin Engineering University. Test modal used with a scale of 1∶[KG-*2]70, which was the standard modal prescribed by 20th International Towing Tank Conference (ITTC).The semisubmersible drilling platform was tested in regular waves with the model oriented in the head, beam and quartering directions. Results were obtained as response amplitude operators (RAO) in surge, sway, heave, roll, pitch and yaw. Dynamic responses measured in the modal test were compared with the numerical results and experiment data provided by ITTC. Results show that the experimental measurements match well with the numerical results and the ITTC criterion.
