LNG ship remote monitoring system

Abstract

The invention relates to a remote monitoring system for LNG ships. The AIS system of the LNG ship supervision platform analyzes the AIS message to obtain the information of the supervised ship for positioning, and displays the position of the ship through the electronic chart system; For personnel with different authority, display the corresponding supervision data and query statistics of the ship. The system of the present invention integrates informatization, networking, intelligence and visualization technologies, and can cover the entire LNG ship and the inner sea area of ​​the LNG wharf for remote supervision on LNG ships, achieving remote visual supervision, information collection, paperless office, and all-weather The purpose of supervision is to solve the problems of insufficient functions of traditional monitoring equipment, automatic assessment of the navigation safety of LNG ships, identification of risk sources in berthing, unberthing and unloading operations of LNG ships, AHP, and fuzzy comprehensive evaluation. , maritime affairs, LNG receiving stations and other departments.

Description

technical field [0001] The invention relates to risk control and remote supervision of LNG ships in the field of water transportation, in particular to a remote monitoring system for LNG ships. Background technique [0002] Natural gas liquefaction can greatly save storage and transportation space and cost. It has the characteristics of large calorific value and high performance. As a clean energy that can replace automobile fuel, it is safe, convenient and less polluting. It is more and more widely used in the fields of industry, transportation and residential life widely. The LNG ship is a special ship for transporting liquefied gas at a low temperature of -163°C. It is a "three-high" product of high technology, high difficulty, and high added value, and is a kind of "marine super freezer". How to make LNG ships better serve the development of national new energy maritime transportation is of great significance. Due to the high specificity and danger of LNG transportatio...

AI Technical Summary

Problems solved by technology

[0007] However, the existing LNG ship risk control and remote supervision methods lack networking, automation and information technology

At present, only according to the navigation safety assessment specification (standard) of the LNG terminal project in the port area, the weather forecast, visibility, tide, wind and wave, LNG special channel, anchorage and emergency anchorage, temporary anchorage, gate and Due to different factors such as harbor basin waters, navigation aid marks, ship pilotage, time of entry and exit, traffic flow, maneuverability, ship size, maritime supervision and escort, navigation aids, agency assistance, ship-shore team organization and cooperation, etc. The degree of influence of various factors is also different depending on the environment and traffic flow conditions. It is difficult to make a reliable comprehensive judgment based on these factors alone. For the sake of safety, the influence of some factors is artificially exaggerated, and the LNG The key issue of the cost of ship berthing operations is the lack of Internet technology, database sharing, online organization and implementation, and intelligence among these factors

[0008] On the other hand, the berthing, unberthing and unloading operations of LNG ships require on-site supervision, lack of unmanned operation, and each link of LNG ship berthing, berthing and unloading operation supervision requires human participation, and there is no online visual remote safety supervision for LNG terminals system, there is no remote warning and law enforcement equipment, resulting in the inability to monitor illegally intruded ships in real time, and to warn and enforce laws against these illegal ships, seriously deteriorating the operating environment of LNG receiving stations
