Example Embodiment

[0026] Such as figure 1 As shown, the present invention includes GPS, gyro compass, computer, monitor and total station. It can be seen from the figure that all other devices are connected to the computer, and the computer comprehensively processes the information of various devices, in order to solve other problems. The problem that the devices are not close in space. The present invention also includes a wireless data link, which is used for the problem that each device is far away from the computer and is inconvenient for direct communication. In order to effectively locate the position and position of the jacket, in the present invention Two total stations are also included.

[0027] The present invention will be further explained below in conjunction with the drawings and the working process of this example;

[0028] Such as figure 2 As shown, the installation of the jacket positioning system follows the following steps:

[0029] 1. Determine the installation position of the t...

Abstract

The invention provides an unmanned high-precision locating system used for mounting a deep sea jacket. The unmanned high-precision locating system is characterized in that the locating system comprises a GPS, a gyrocompass, a computer, a displayer and a total station, the GPS is connected with the computer, the gyrocompass is connected with the computer, the displayer is connected with the computer, and the total station is connected with the computer. The unmanned high-precision locating system has the advantages that according to the technical scheme, inconvenience caused by the mounting characteristic of the deep sea jacket is removed, the jacket is mounted and located more conveniently, and meanwhile the mounting and locating precision of the jacket is improved.

Description

technical field [0001] The invention belongs to the field of marine measurement and positioning, and in particular relates to an unmanned high-precision positioning system for deep-sea jacket installation. Background technique [0002] The jacket installation and positioning of the traditional offshore oil production platform is realized by GPS positioning and gyro compass orientation. It is necessary to install GPS and gyro compass on the jacket during the jacket installation process, and measure and calculate the GPS antenna position in real time during the hoisting process. Although this method is more intuitive, there are still big problems, especially in the installation of deep water jackets, which are mainly reflected in the following aspects: [0003] 1. During the installation of the jacket, the pole of the workboat and the base of the crane block the signal space of the GPS, which will generate about 30%-40% of the signal space and affect the measurement accuracy o...
