摘要
根据南海海域海洋981半潜式深水钻井平台的实际工况,分析了该钻井平台与锚泊系统的风、浪、流等环境载荷;以海洋石油981半潜式深水钻井平台作为锚泊定位系统研究的对象,应用AQWA进行模拟仿真,建立了平台的三维模型,并分析了钻井装置在波浪载荷作用下的运动响应;鉴于该深水钻井装置采用12点对称布锚方式被固定在海平面上,通过改变顶部预张力倾角,分析在不同环境载荷下,顶部预张力倾角对锚泊系统的张力响应和钻井装置运动响应的影响。
The environmental loads such as wind,wave,flow onto drilling rig and mooring system of the HaiYangShiYou 981 are analyzed according to the actual working condition in South China Sea.The Haiyang Shiyou 981 drilling rig is chosen as the research object for mooring positioning system.The 3Dmodel of the platform is established first by using the AQWA software to simulate and analyze the motion response of the drilling device under the action of wave load.As the deep water drilling rig is fixed in the sea with twelve anchors which are symmetrical distribution,the influence of top pretension angle on dynamic response of mooring system and motion response of drilling rig under different environmental load is analyzed by changing the inclination angle of the pretension at the top of the drilling rig.
