基于AQWA的新型半潜式海洋钻井平台水动力特性研究

A Study on the Hydrodynamic Characteristics of a New Semi-submersible Based on AQWA

首先,该文针对现役深水半潜式平台在风浪流中产生的升沉误差进行最优补偿,并依据规范设计了一种新型半潜式平台基本结构,建立三维水动力模型;其次,利用AQWA软件对目标平台进行频域下的水动力分析,得到平台的运动响应数据;最后,根据规范设计了一种新型半潜式平台的锚泊系统,对平台与锚泊系统进行时域耦合分析,为目标平台的控制提供精确预报,保证实时稳定性,调高作业人员舒适度。

Firstly,in order to make the compensation for the active deepwater semi-submersible platform,which produce heave error in the deep flow and storms.A new type of semi-submersible platform is designed and the three-dimensional hydrodynamic model is made;Secondly,the water dynamic analysis of the target platform is carried out in the frequency domain depending on the AQWA,and the motion response of the platform is obtained;Finally,according to the code for design of a new type of semi submersible platform mooring system,on the platform and mooring system are time domain coupled analysis,providing a precise prediction for the control of the target platform to ensure real-time stability,and to improve operators’ comfort.
