本文讨论坐底式钻井船漂浮状态的总强度计算分析问题。应用拟静力法计算坐底钻井船在斜浪、迎浪、横浪等不利的受力状态时的作用载荷;根据该船结构特点,将全船化为空间梁系,引用“OSAS-2”半潜式海上钻井平台结构总强度分析程序,经过前处理,进行总体弯扭强度计算,为这类钻井船的设计提供了计算依据;也为专用程序的扩大使用取得一些经验。
This article discusses the total strength calculation and analysis of floating drilling rigs. The quasi-static method is used to calculate the acting load of the bottom-drilling rig in the unfavorable stress state of inclined waves, waves and waves. According to the structural characteristics of the ship, the whole ship is converted into a space beam system. Reference is made to “OSAS-2 ”The overall strength analysis program of semi-submersible offshore drilling platform structure, after pretreatment, carries out the calculation of overall bending and torsional strength, which provides the basis for calculation for the design of this type of drilling vessel and also obtains some experience for the expanded use of special procedures.
