The environmental load chart is an important technical support required for the jack-up drilling platform to facilitate its adaptation to different operating waters and ensure the safety of operation. This chart is a crucial part of the platform operation manual. The chart data are closely related to external factors such as water depth, wind, wave, and current conditions of the working water, as well as to the structural characteristics of the platform itself and the number of variable loads.

三体船横摇惯性半径的估算方法研究 总被引:1,自引:0,他引:1
三体船的研究与应用极大地推进了高速船舶的发展.对三体船耐波性研究的重要工作内容之一是确定其横摇惯性半径,以计算船舶的横摇周期等.由于三体船的特殊结构,横摇惯性半径的确定方法与单体船型有所不同.在三体梁简化模型的基础上,通过对计算结果的拟合与修正,找到了三体船横摇惯性半径计算的相关参数,得出三体船惯性半径的估算公式,并通... 相似文献
