摘要
张力腿平台作为一种深水平台 ,其半顺应半固定的运动特征 ,成为在复杂的深海海洋环境中进行海洋石油勘探、开采一种重要结构型式。在张力腿平台波浪载荷的计算中根据产生波动流场的因素不同将波浪载荷分为绕射效应和辐射效应。本文对辐射效应深入研究并以附加质量、附加阻尼等水动力参数的形式计算了辐射效应对张力腿平台的载荷影响。在计算水动力参数时将平台简化为浮式直立柱群 ,采用势流理论 ,引进改进平面波法计入柱体间水动力相互作用得到辐射波速度势的半解析解 ,引入大间距假设、通过非平面波修正 。
TLP is the main platform in deep sea for its partly compliant and partly rigid feature. The interaction between wave and TLP includes two parts: one is wave diffraction, the other is wave radiation. Wave radiation is studied in this paper. In calculating the hydrodynamic parameters of TLP, TLP can be idealized into an array of stationary, truncated circular cylinders. An approximate method of equivalent plane waves is utilized to investigate the hydrodynamic interactions between the members of TLP's truncated vertical cylinder array which occur when one member undergoes prescribed forced oscillations.
