浮式钻井平台升沉运动分析

摘要

When the Drilling Platform floats on sea,there are some kinds of movements induced by the wave,such as heave motion,rocking and floating motion. The heave motion mf floating drilling platform under the wave condition was mainly analyzed and the mathematical model of it was established. The influence of the heave motion on the Platform was described and the relation during the heave motion,wave height and the wave period is established. At last,the calculation theoretics of the heave motion is verified by the deep water survey ship project. It is a reference for e-quipping the Heave Compensation Equipment for the floating Drilling Platform.%浮式钻井平台(船)在海上处于漂浮状态时,由于风浪的作用会产生升沉、摇摆、漂移等运动.重点分析了浮式钻井平台(船)的升沉运动特性并建立了运动数学模型,阐述了其对钻井船的影响,找出了钻井船升沉与波高、波浪周期的关系,并通过深水工程勘察船的工程实例对上述理论进行了验证,为浮式平台配套升沉补偿装置的设计提供依据.
