Weighing method and independent weighing units of large ocean function module

Abstract

The invention discloses a weighing method of a large ocean function module. The weighing method of the large ocean function module comprises the following steps that A, according to structural style characteristics and tonnage of a generator module, 12 independent weighing units are selected to weigh the generator module; B, the 12 independent weighing units are arranged on the designated position of the generator module; C, the generator module is wholly ejected by 10mm through 12 hydraulic lifting jacks, after numerical reading in a data display is recorded, the 12 lifting jacks are decompressed, and then are repeated ejected twice, and statistics of the numerical reading is conducted; D, three-time numerical reading is respectively conducted analysis processing, a torque balance principle is utilized to respectively compute the gravity center place of the generator module. The weighing method of the large ocean function module can save a large amount of manpower and resources, shortens a ship construction period, simultaneously achieves synergia aim, lays a solid foundation for improving safety and accuracy of lifting of the module, reducing harmful factors, and preventing overweight conditions of the ship in the process of lifting of the module from occuring and has popularization value in China.

Description

technical field [0001] The invention relates to a method for weighing a large marine functional module. Background technique [0002] In the prior art, with the discovery of large-scale deep-sea oilfields in the world, the demand for large-scale marine functional modules is gradually increasing. These modules often have the characteristics of large flexibility, uneven weight distribution, and large spans of support points, which are very important for offshore construction. High requirements are put forward, and strict scientific control of weight and center of gravity is required. However, due to various reasons during the construction process, it is difficult to control the center of gravity and weight distribution of marine functional modules. [0003] The installation design of the marine functional module is an important part of the drilling ship and FPSO (floating production storage and offloading unit). The weight and center of gravity distribution of the marine funct...
