| 摘 要： | 针对海洋结构物的过程对象模型中水动力系数较多且较难获得准确的数值,运用控制对象模型代替过程对象模型来模拟海洋平台动力定位时的动态响应.采用模块法对半潜式平台主要的水上建筑以及水下建筑进行了不同标准构件模块的离散,通过叠加各离散构件的载荷获得风与海流的总载荷.应用所建立的模型对981钻井平台在待机工况与作业工况进行了动力定位的时域仿真,仿真结果表明模型切实可行,可以用于动力定位的实时模拟与系统调试.

| Abstract: | Due to some hydrodynamic coefficients of process plant model are difficult to obtain accurate values,control plant mode was used to simulate dynamic response of drilling units instead of process plant model.A modular method was introduced to separate the buildings above and under the waterline of rig into different standard components respectively,and the total wind and current load acting on the rig were obtained by accumulating the loads of corresponding discrete standard components.Time-domain simulation... |
