Device and method for monitoring subsidence of jacket platform based on inclination angle monitoring

Abstract

The invention relates to a device and a method for monitoring the subsidence of a jacket platform based on inclination angle monitoring, which belong to the technical field of monitoring of jacket platforms. The device comprises inclination angle sensors, transmission wire cables, a data acquisition mechanism and a host monitor, wherein the inclination angle sensors are connected with the data acquisition mechanism which is connected with the host monitor; and spud legs and cross beams between the spud legs are arranged on the jacket platform, and the inclination angle sensors are installed on the cross beams of the jacket platform. In the method, the inclination angle sensors are arranged on the cross beams of the jacket platform, the host monitor acquires inclination angle signal data of the inclination angle sensors on the jacket platform in real time through the data acquisition mechanism, and the comparative analysis is carried out on the inclination angle signal data and a preset value for monitoring the subsidence of the jacket platform. The device and the method have the advantages of convenience in monitoring, real-time on-line monitoring, quick response, accurate data, graded pre-warning, security, reliability and the like.

Description

technical field [0001] The invention belongs to the technical field of jacket platform monitoring, in particular to a jacket platform settlement monitoring device based on inclination monitoring and a monitoring method thereof. Background technique [0002] At present, the jacket platform, also known as the pile-based platform, is the most widely used and mature platform structure in offshore oil fields. The jacket platform structure has served in the harsh marine environment for a long time, and is subject to the interaction of various loads, such as wind loads, ocean currents, wave loads, ice loads, etc., and sometimes earthquakes, typhoons, tsunamis, ship collisions and other accidents In the event of disasters, the structure itself will also be affected by environmental corrosion, marine biological adhesion, seabed scour, etc. Under the long-term action of these harsh environmental loads, it is easy to produce various forms of damage, reduce the bearing capacity of the ...

AI Technical Summary

Problems solved by technology

Under the long-term action of these harsh environmental loads, it is easy to produce various forms of damage, which will reduce the bearing capacity of the structure, pose a potential threat to the platform, and even lead to platform failure in severe cases.

So far, for the safety online monitoring of the jacket platform structure, there is no systematic and mature monitoring system that can be applied. The monitoring is not timely, the alarm cannot be graded, and there are problems such as hidden dangers in the work and production of the jacket platform.
