Embodiment 1

[0062] A multi-platform foundation pile ROV collaborative operation system, such as figure 1 As shown, including dispatching route optimization system, wind wave and current monitoring system, ROV umbilical cable control system and ROV intelligent control system;

[0063] The dispatching route optimization system is used to: based on the current position of the tugboat, the position of the demand platform and the position of the platform with available ROV, based on the optimization principle, to optimize an optimal tugboat route; the wind, wave and current monitoring system is used to: find out about The relevant parameters of the marine environment; the ROV umbilical cable control system is used to: automatically control the lowering and recovery speed of the umbilical cable; the ROV intelligent control system is used to: intelligently control the ROV to find underwater targets and ROV underwater operations.

[0064] Such as image 3 As shown, the ROV umbilical cable contro...

Embodiment 2

[0066] A multi-platform foundation pile ROV collaborative operation method, based on the multi-platform foundation pile ROV collaborative operation system described in embodiment 1, such as figure 2 As shown, for the technical failure of the ROV carried by the current platform itself or when encountering an emergency or to improve work efficiency, multiple ROVs are often required to work together. At this time, it is necessary to call the ROV to the adjacent platform. Specifically, in order to complete the collaborative construction of ROV, it is necessary for the platform, tugboat and ROV to work together, including the following steps:

[0067] (1) Optimize the adjacent platform ROV; based on the current position A of the tugboat, the position of the demanded platform B and the platform position of the available ROV, through the dispatching route optimization system, based on the optimization principle, an optimal tugboat route is selected;

[0068] (2) tugboat scheduling R...

Embodiment 3

[0075] According to a kind of multi-platform foundation pile ROV collaborative operation method described in embodiment 2, its difference is:

[0076] In step (1), preferably adjacent platform ROV, comprises steps as follows:

[0077] A. Start the scheduling path optimization system, and globally initialize the parameters of the scheduling path optimization system;

[0078] B. Input the position of the required platform, the current position of the tugboat, the position of the platform with available ROVs, and the number of required ROVs in the scheduling route optimization system;

[0079] C. Read the relevant parameters about the marine environment obtained through the wind, wave and current monitoring system. The relevant parameters about the marine environment include average wind speed, wind direction, average wave wavelength, average cycle, average wave speed, average wave height, flow direction and current velocity, and calculate the affected The comprehensive path coe...

Abstract

The invention relates to a multi-platform foundation pile ROV cooperative operation system and method. The multi-platform foundation pile ROV cooperative operation system comprises a scheduling path optimization system, a wind wave flow monitoring system, an ROV umbilical cable control system and an ROV intelligent control system, the scheduling path optimization system is used for optimizing an optimal tugboat route based on a current position of a tugboat, a position of a demand platform, a position of a platform with an available ROV and an optimization principle; the wind wave flow monitoring system is used for solving related parameters about a marine environment; and the ROV umbilical cable control system is used for automatically controlling a lowering speed of the umbilical cable.By adopting the integrated tugboat, ROV and platform, the four systems and a cooperative operation method provided by the invention, the safe and efficient operation of the ROV is ensured.

Description

technical field [0001] The invention relates to the technical field of offshore oil and gas development engineering, in particular to a multi-platform foundation pile ROV collaborative operation system and method. Background technique [0002] Since the beginning of the 21st century, with the continuous growth of population and the continuous expansion of industrial demand for oil and gas resources, most oil and gas fields in traditional areas, such as land and shallow seas, have entered the middle and late stages of development, and their production capacity has been severely depleted, making it difficult to meet the gradually expanding energy demand. Therefore, the new The footsteps of oil and gas exploration and development in the century have gradually entered deep water and ultra-deep water. At present, the deep water in the South China Sea is the main replacement area for oil and gas resources in my country. However, due to its harsh marine environment, it faces a huge...
