Problems solved by technology

This method is ideal when there are few legs, but when the number of legs is large, the measurement data of a limited number of base stations is very limited. None of these methods can measure the positions of dozens of leg columns with high precision

Embodiment 1

[0016] To measure the position coordinates of the multi-leg column on the deck of the multi-leg column module, the following steps are adopted:

[0017] (1) Establish the reference coordinate system of the deck plate; (2) Select the key measurement point of the module for measuring the spatial position coordinates of each leg column of the deck plate and use the key measurement point of the module as the coordinate origin to establish a relative coordinate system to determine the key measurement of each module The coordinate position of the point in the reference coordinate system of the deck sheet; (3) measure the spatial position relative coordinates of each leg column of the deck sheet that the measuring device can measure at each module key measurement point by the measuring device; (4) The relative coordinates of the spatial positions of each leg column of the deck sheet are converted into coordinates in the reference coordinate system of the deck sheet through the coordin...

Abstract

The invention discloses an installation measurement method of a multi-leg pole modular deck sheet. The method comprises the following steps of: (1) building a reference coordinate system of the deck sheet; (2) selecting a modular key measurement point for measuring a space position coordinate of each leg pole, and taking the modular key measurement point as a coordinate original point to build a relative coordinate system; and measuring the coordinate position of each modular key measurement point in the reference coordinate system of the deck sheet; (3) measuring the space position relative coordinate of each leg pole of the deck sheet which is measured by a measurement device at each modular key measurement point through the measurement device; and (4) converting the space position relative coordinate of each leg pole of the deck sheet into the coordinate in the reference coordinate system of the deck sheet through the coordinate converting relation determined in the step (2), so as to obtain a leg pole installation position. By adopting the method, the high-precision leg pole measurement data can be obtained; the size and the deformation precision of the structure can be guaranteed during the construction process; and the fitting precision and whole error precision of the structure during the final installation process can be guaranteed.

Description

technical field [0001] The invention relates to an installation measurement method, in particular to a multi-leg column module deck sheet installation measurement method. Background technique [0002] In offshore oil development projects, various platforms such as oil production platforms, living platforms, and central processing platforms need to be built offshore. The platform generally mainly includes: marine engineering blocks, underwater support structures - jackets, single points and other marine structures. Offshore engineering blocks, jackets, single points, etc. are commonly referred to as offshore structures. Marine structures generally have the characteristics of heavy weight, many structures, and complex construction. As the weight and volume of structures continue to increase, the construction process of structures requires layered and block-by-block construction. This method can effectively shorten the construction period, improve production efficiency, and ...
