半潜平台总体强度模型重量重心调平方法

摘要

分析半潜式钻井平台重量分布特点，结合重量分布与重心计算原理，将平台按照重量分布分块，推导出可以准确模拟平台的真实重量重心的参数方程，工程实例计算验证该方法的可行性与可靠性，结果表明该方法能够在满足工程精度要求的前提下，快速完成总体强度模型调平工作。%The weight distribution feature of the semi submersible platform is analyzed.In terms of the calculation principle of weight distribution and center of gravity, the platform is separated into different part by weight distribution, and the parameter equations is deduced for simulating the weight of platform accurately.The feasibility and reliability of this method are validated by real engineering project.The results prove that the proposed method can quickly accomplish the mass balancing job and satisfy the precision requirement.
