Embodiment Construction

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] The thruster-assisted mooring positioning system based on the automatic monitoring and control technology involved in the present invention includes a drilling platform 2 , a sensor system 3 , a mooring system 4 , a wind compensator 9 , an observer 10 , a mooring monitoring system 11 , a controller 13 , and a propulsion system 14 . The sensor system 3 includes a tension sensor 5 , a compass 6 , a GPS 7 and a wind sensor 8 . The invention includes a mooring monitoring system, the mooring monitoring system estimates the tension of the mooring system anchor chain according to the tension information of the anchor chain provided by the tension sensor, and transmits it to the observer; at the same time, when the estimated value of the anchor chain tension is greater than When the anchor chain tension is set to the threshold value and lasts for a certain period of time...

Abstract

The invention relates to an automatic monitoring and control technology-based drilling platform propeller auxiliary anchoring positioning system. The automatic monitoring and control technology-based propeller auxiliary anchoring positioning system comprises a drilling platform 2, a sensor system 3, an anchoring system 4, a wind power compensator 9, an observer 10, an anchoring monitoring system 11, a controller 13 and a propelling system 14. The sensor system 3 comprises a tension sensor 5, a compass 6, a GPS7 and a wind sensor 8. The enabling strategy of the controller is performed through monitoring the tension state of the anchoring system in real time; when the marine environment is adverse, the tension of an anchor chain exceeds the set threshold, and the condition lasts for a period of time, the controller is made to participate in positioning control of the drilling platform, to decrease the tension of the anchor chain of the anchoring system and prevent the anchor chain from being broken due to excessive tension, the auxiliary anchoring and positioning functions of propellers are fulfilled, and thus the adaptability, to the marine environment, of the drilling platform is enhanced.

Description

technical field [0001] The invention relates to a drilling platform thruster auxiliary mooring positioning system based on automatic monitoring and control technology. Background technique [0002] At present, the development of offshore oil at home and abroad is increasingly tending to the deep-sea field. In order to meet the needs of engineering operations in the harsh environment of the deep sea, the deep-sea drilling platform must be moored in a specific sea area for a long time, and it cannot be used when encountering severe wind and waves. avoidance, so this poses a huge challenge to the platform's positioning system. In recent years, dynamic positioning system has appeared and developed rapidly, but its initial investment and operation cost are relatively high. Therefore, the research on mooring system of deep-sea drilling platform also has important significance and research value. [0003] Domestic research on propeller-assisted mooring systems is still relatively...
