A docking and positioning guidance method for offshore oil drilling platforms

Abstract

The invention provides a docking positioning guiding method for an offshore oil drilling platform. The method is characterized by integrating inertial navigation, satellite navigation and optical measurement technologies, and utilizing measurement information of an optical-fiber gyro attitude heading reference system, a differential GPS (global positioning system), a gyrocompass and multiple sensors of a total station to establish a time and space uniform benchmark of multiple sensors by synchronously processing data time and space, and thus the three-dimensional high-precision measurement of docking positioning guidance is realized; a non-reset federated kalman filter is utilized to integrate the information, and then the docking guiding information is outputted; through the data after-treatment of the information of the differential GPS, faults of the system can be monitored, and the system reliability and fault tolerance can be improved; by virtue of a virtual reality technology, the whole-process three-dimensional display of the entire docking process can be realized. The method can be used for effectively guiding the docking of a drilling platform and an oil production platform.

Description

technical field [0001] The invention relates to a full-parameter three-dimensional docking positioning guidance method for an offshore drilling platform and an oil production platform, in particular to a docking positioning guidance method for an offshore drilling platform. Background technique [0002] In order to meet higher precision and reliability requirements and save manpower and material resources in offshore engineering, the docking of offshore oil drilling platforms not only requires the system's work adaptability in harsh environments, but also requires the system to be able to provide real-time three-dimensional relative position and speed. , posture and other information, providing decision makers with intuitive, accurate and real-time docking status parameter information during the dynamic application process. [0003] At present, there are few studies on the docking operation of offshore drilling platforms. The "Multifunctional Positioning and Guidance System...

Problems solved by technology

The "Multifunctional Positioning and Guidance System for Ships", which is at the leading level in China, can provide two-dimensional positioning information, but its accuracy is average, it does not have high-precision target tracking capabilities, and there is no real-time display of virtual reality scenes during the docking process; foreign countries are more common for drilling platforms. It is a position reference system / position monitoring equipment, its system composition and installation are complex, the capital and fuel consumption are high, the accuracy is average, and it is highly targeted, and it is inconvenient to expand and apply
