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
[0004] 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

Embodiment Construction

[0031] The invention provides an on-site monitoring system suitable for the turret-type single-point mooring system in the South China Sea, including wind, wave, temperature, humidity, and air pressure environmental conditions in the FPSO operating sea area, FPSO heading, single-point position, FPSO Six-degree-of-freedom movement, the force of the mooring anchor chain, etc. are monitored. In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0032] The single point consists of an inner turret embedded in the bow and a conical mooring buoy connected by structural connectors. The buoy consists of a buoy and a turret, and the buoy can provide enough buoyancy to bear the weight of the mooring legs and risers. The transmission of the recovery force of the anchor chain is transmitted to the mooring buoy thr...

Abstract

The invention relates to the field of oilfield operation safety and provides a scientific and effective field monitoring technology applicable to a deep water turret-type single point mooring system, which can monitor wind, wave, temperature, humidity, air pressure environmental conditions of a FPSO (Floating Production Storage and Offloading) operation sea area, FPSO heading, a single point position, FPSO six-degree of freedom motion, and a stressed force of a mooring cable, provide timely and accurate mooring safety information for an operation manager, enable the operation manager to perform safety management with a plan and ensure FPSO safety operation. The field monitoring system applicable to the deep water turret-type single point mooring system in the adopted technical scheme comprises a wave radar used to obtain a wave height, an anemoclinograph for acquiring a wind speed, a temperature, humidity and air pressure integrated machine, a GPS antenna (that is, a mobile station), an inertial measurement unit (IMU), a mooring inclinometer and a UPS system for providing uninterrupted power supply for all monitoring devices. the system of the invention is mainly applied to an oilfield device design and mounting situation.

Description

technical field [0001] The invention relates to the field of oil field operation safety, in particular to an on-site monitoring system of a deep-water inner turret type single-point mooring system. [0002] technical background [0003] 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. [0004] In recent years, due to the increasingly harsh marine environmental conditions, accidents / failures of single point mooring systems caused by extreme weather have occurred frequently, which has brough...
