摘要
RPD是桁架式桩腿两相邻弦杆的垂向位移差。自升式海洋平台在升船、预压升船及预压载等工况下,桩腿RPD值不允许超过其最大可容许值。以一个桁架式桩腿的自升式海洋平台为例,论述了RPD计算原理和计算方法,进行了详细的数值计算,并分析得到桩腿的最大可容许RPD值。论文提供的方法和思路对自升式平台使用者及平台设计人员具有一定的指导意义。
The RPD represents the differential vertical displacement between each chord of one leg. The maximum allowable RPD is the value that should not be exceeded under jacking, pre-load jacking and pre-load holding conditions. Theory and method of RPD calculation are studied and suggested respectively in this paper. As an example, the maximum allowable RPD for a jack-up with truss legs is determined. This paper may be helpful to the rig owners, operators and designers.
