Test system and method for drill platform mass centre

Abstract

The invention discloses a gravity center testing system for a drilling platform and a testing method thereof. The testing system comprises a power supply source, a plurality of parallel and autonomous working hydraulic drive mechanisms for synchronously jacking and lowering a drilling platform to be tested in parallel, a plurality of pressure sensors for respectively detecting bearing pressures of a plurality of hydraulic drive mechanisms in real time, displacement sensors for respectively detecting jacking displacement or lowering displacement of a plurality of hydraulic drive mechanisms in real time, and a control system for analyzing to obtain barycentric coordinates of the drilling platform. Signals detected by the pressure sensors and the displacement sensors are sent to the control system via an A / D conversion circuit, and the control system controls dynamic mechanisms of a plurality of hydraulic drive mechanisms. The testing method comprises steps of preparing, zero setting, synchronously jacking and weighing, as well as synchronously lowering and testing the gravity center. The gravity center testing system has reasonable structure and simple testing method, is convenient to be realized with high test precision, and can effectively solve the problems in drilling platform gravity center testing.

Description

technical field [0001] The invention relates to the technical field of research on the earth's gravitational field, in particular to a center-of-gravity testing system and a testing method for a drilling platform. Background technique [0002] In the field of marine engineering technology, the measurement of the center of gravity of the drilling platform is a common construction problem, especially when operating on a ship, accurately finding the center of gravity of the drilling platform is a key issue related to the success of the project construction. There is still no simple and effective drilling platform testing system and its testing method at present, and most of them usually find the center of gravity of the drilling platform manually. However, manually finding the center of gravity of the drilling platform is not only time-consuming, laborious, and low in operability, but also has poor accuracy. There are often situations where the found center of gravity is quite ...

At present, there is no simple and effective drilling platform testing system and testing method, and most of them are usually manually looking for the center of gravity of the drilling platform

However, manually finding the center of gravity of the drilling platform is not only time-consuming, laborious, and low in operability, but also has poor accuracy. There are often situations where the found center of gravity is quite different from the actual center of gravity, which will eventually bring great inconvenience to subsequent construction, and even fall into the Difficulty in normal construction
