Movement actual measurement method and system of jacket platform water entering process

Abstract

The invention discloses a movement actual measurement method of a jacket platform water entering process and a movement actual measurement system of the jacket platform water entering process. The movement actual measurement system includes a combined measurement module, a watertight module, a data storage module, a power supplying module, a real-time monitoring computer, a GPS antenna and a radio frequency signal transmission line, wherein the combined measurement module includes a GPS measurement system and an inertial navigation system, and the combined measurement module, the data storage module and the power supplying module are arranged in the watertight module. According to the movement actual measurement method and system of the jacket platform water entering process of the invention, the combined measurement module system is adopted; the GPS system and the inertial navigation system are combined with each other; when signals exist in the GPS system; the GPS system can output position signals to the inertial navigation system in a real-time manner; errors of the inertial navigation system caused by quadratic integral can be corrected, and measurement precision can be ensured; and therefore, difficulties in actual parameter measurement in the jacket platform water entering process can be eliminated.

Description

technical field [0001] The invention relates to the field of ships and ocean engineering, in particular to a method and system for measuring and collecting the movement of a jacket and a barge during the launching process of a jacket platform. Background technique [0002] As an important research method in the field of ship and ocean engineering, the actual measurement at sea has been paid more and more attention in recent years. The actual measurement results truly reflect the movement of ships and marine structures in actual sea conditions. It is often used as the most original and reliable data, and is widely used in the verification of numerical simulation and model test results in scientific research. Or in the design stage of ships and marine structures, the measured data can often provide good reference value. [0003] The steel jacket structure is currently the most widely used platform structure in offshore oil and gas fields. Compared with other types of offshore...
