Embodiment Construction

[0035] The hybrid positioning system for water structures provided by the embodiments of this application solves or partially solves the technical problem that the positioning technology in the prior art is insufficient to meet the precise positioning requirements of large offshore floating platforms, and realizes that the tension leg system unit group It is integrated with the dynamic positioning system technology to limit the six-degree-of-freedom movement of water structures such as heave, roll, pitch, sway, sway and yaw. According to the requirements of structure positioning and stability, the tension is comprehensively utilized The leg system positioning and dynamic positioning system perform automatic positioning compensation to achieve the technical effect of fully automatic and precise positioning.

[0036] See attached figure 1 with 3 This application provides a hybrid positioning system for water structures, including: a tension leg system composed of a tension leg ancho...

Abstract

The invention relates to an overwater structural object hybrid positioning system which comprises a hybrid positioning system body of a tension leg system and a power positioning system. An overwater structural object and a water bottom geologic structure are connected by the tension leg system through tension leg tendons and anchoring foundations, and the heaving motion, the rolling motion and the pitching motion of the overwater structural object in the vertical direction are restrained. The displacement and direction changes, generated due to the wind, wave and flow effects, of the overwater structural object are measured by the power positioning system through a sensor system and a position reference measurement system, information is processed and calculated in real time through a computer and other automatic control systems, the thrust and the moment of multiple propellers in different directions are automatically controlled, the overwater structural object is reset to the original position, and the surging motion, the swaying motion and the yawing motion in the horizontal direction are controlled. The tension leg system and the power positioning system conduct hybrid positioning, the six-freedom motion of heaving, rolling, pitching, surging, swaying and yawing of the overwater structural object is restrained, automatic positioning compensation is achieved, and full-automatic accurate positioning is achieved.

Description

Technical field [0001] The invention relates to the technical field of offshore platforms, in particular to a hybrid positioning system for water structures. Background technique [0002] At present, the large-scale offshore platform technology in the deep ocean is a new concept of offshore floating structure. The technology is world-leading and the products are widely used. It belongs to the new marine engineering equipment industry and will enable China to take the lead in mastering the engineering of "ultra-large offshore platforms" The core technology of the company, grasp the strategic opportunity. Based on the basic structure of a large / ultra-large offshore floating platform, the platform's deep-sea anchor positioning technology is a highly technically difficult and complex offshore project. The existing water platform positioning technology mainly includes anchoring positioning, tension leg anchor fixed position, eight-point anchoring and dynamic positioning. [0003] The ...
