Ship marine operation assistant decision support system based on mobile terminal

Abstract

The invention discloses a ship marine operation assistant decision support system based on a mobile terminal and belongs to the technical field of shipbuilding and oceanography engineering. Accordingto the ship marine operation assistant decision support system based on the mobile terminal, through weather forecast and a shipborne sensor, ocean environment basic information of a sea area where aship is located is obtained; through a systematic ocean wind wave theoretical model, ocean wind wave fields around the ship are built; through a super computer or cloud computing, real-time simulationis conducted on ship movement to obtain ship movement responses, and by combining relevant marine operation norms and the ship movement responses, marine operation assistant decision information is given; and the assistant decision information can be real-timely fed back to a user on the ship through the mobile terminal. The ship marine operation assistant decision support system based on the mobile terminal can provide assistant decision support for ship marine operation scheme design and implementation, at the operation scheme design stage, the possible dangerous situations are evaded or early warned, and the ship marine operation assistant decision support system has wide market application prospects and good social benefits and economic value.

Description

technical field [0001] The invention belongs to the technical field of ships and ocean engineering, and in particular relates to a mobile terminal-based auxiliary decision-making support system for ships' offshore operations. Background technique [0002] Marine economy is an important part of my country's economy, and it is a field that my country will focus on and develop in the 21st century. With the gradual deepening of the development and utilization of marine resources and the promotion and implementation of the major national strategies of the Belt and Road Initiative, activities such as marine fishery, marine mineral resource development, and maritime transportation have become increasingly frequent. Ships are an important tool for people to explore the ocean, develop offshore oil and gas and mineral resources, and transport at sea, and are widely used in various fields of ocean engineering. [0003] For ships, from design to full life-cycle operation, ocean wind an...

AI Technical Summary

Problems solved by technology

At present, there are two main deficiencies in the decision-making technology and information services for offshore operations: first, the marine environment information provided by the weather forecast is very rough, and its spatial resolution is far greater than the scale of the ship itself; Information such as frequency characteristics cannot be effectively provided; second, the existing operational decision-making is based on marine meteorological information itself, which is an indirect judgment method relying on experience, and the specific motion state of the hull itself is not known.

[0006] At present, there is no similar or identical offshore operation decision support system at home and abroad
