Accurate positioning method for offshore installation of deepwater jacket
The invention discloses an accurate positioning method for offshore installation of a deepwater jacket. The method comprises the following steps: firstly, establishing a jacket three-dimensional structure model and a seabed three-dimensional digital model of an operation site in a computer model system; the data transfer radio transmits the position data of the global navigation satellite system receiver and the attitude data of the attitude sensor to the computer model system; real-time calculation is carried out in the computer model system, current three-dimensional coordinate data of the jacket positioning point are obtained, and the mounting position of the jacket is adjusted according to coordinate deviation data between the current three-dimensional coordinate data of the jacket positioning point and preset mounting coordinate data of the jacket positioning point. And accurate positioning of the jacket installation is completed. The three-dimensional attitude of the jacket can be monitored in real time through the global navigation satellite system and the attitude sensor, the positioning accuracy of the jacket is improved, the working time for accurately positioning the deepwater jacket is greatly shortened, and the labor cost of ships, sky and the like is reduced.
本发明公开了一种深水导管架海上安装精确定位方法，包括以下步骤：首先在计算机模型系统中建立导管架三维结构模型和作业现场的海床三维数字模型；数传电台将全球导航卫星系统接收机的位置数据和姿态传感器的姿态数据传输至所述计算机模型系统；在所述计算机模型系统中进行实时计算，获得所述导管架定位点当前的三维坐标数据，根据所述导管架定位点当前的三维坐标数据与所述导管架定位点预设的安装坐标数据之间的坐标偏差数据，调整所述导管架安装位置，完成所述导管架安装精确定位。本发明通过全球导航卫星系统和姿态传感器能够实时监测导管架三维姿态，提高导管架定位精度，大大缩短了深水导管架精确定位的工时，减少了船天等用工成本。
