Problems solved by technology

Among them, the single-point mooring system is an important link related to the normal operation of the entire FPSO. Once the FPSO single-point mooring system is damaged, the safety of the entire FPSO will be greatly threatened. Bring serious economic losses, and there is a risk of oil spills, which may lead to ecological disasters
[0003] In recent years, due to the increasingly severe marine environmental conditions, frequent accidents / failures of single point mooring systems caused by extreme weather have brought severe challenges to oilfield production and facility safety

Abstract

The invention relates to the field of oil field safe operation, and provides a scientific and effective onsite monitoring and prediction technology applied to an underwater soft yoke single-point mooring system in the Bohai bay. Prediction software can be used for providing accurate prediction for mooring response. According to the technical scheme of the invention, the onsite monitoring and prediction system for the underwater soft yoke single-point mooring system comprises a wave current instrument for measurement, an anemoclinograph, a temperature, humidity and air pressure integrated machine, two sets of independent GPS systems longitudinally arranged along the FPSO for acquiring the orientation of the FPSO, a GPS base station, and a GPS mobile station, an inertial measurement unit, a fiber bragg grating strain sensor and an acceleration sensor arranged onto the FPSO. The single-point state monitoring uses all sensors to be connected onto backup channels of the central control system (FOXBORO) for measurement, and acquisition, transmission, display and processing of all measured data can be realized. The system of the invention is mainly applied to oil filed operation.

Description

technical field [0001] The patent of the invention relates to the field of oil field operation safety, in particular to the on-site monitoring and forecasting of the Bohai Sea underwater soft rigid arm type single point mooring system. Specifically, the invention relates to an on-site monitoring and forecasting system for an underwater soft rigid arm single point mooring system. technical background [0002] FPSO (Floating Production Storage and Offloading) is one of the main modes of offshore oil development, and is widely used in crude oil production, storage and export in various sea areas of the world. Among them, the single-point mooring system is an important link related to the normal operation of the entire FPSO. Once the FPSO single-point mooring system is damaged, the safety of the entire FPSO will be greatly threatened. Serious economic losses are caused, and there is a danger of oil spills, which may lead to ecological disasters. [0003] In recent years, due t...
