Description

[0001] The present invention relates to an optimal economic operation support system for a ship,

The present invention relates to a system for optimally operating an economic operation of a ship, more particularly, by designing and navigating an optimal operation route of a ship by applying energy efficiency operation index (EEOI) based on weather forecast, At the same time, CO2 emissions can be reduced, which can lead to economical navigation of the ship and prevent global warming. In addition, it is possible to reset the optimal route of the ship in a timely manner according to the change of the weather conditions. And to an optimal economic navigation support system for a ship which can be guided.

Developing and building a ship with low fuel consumption is at the heart of the future shipbuilding industry. Assuming a ship that consumes a ton of fuel and emits 320 tons of CO2, a 1% improvement in fuel efficiency will save more than $ 240,000 a year, and in about 25 years, about 6 million The dollar can be reduced, and fuel economy is one of the most important factors in the secondary market.

In addition, modern society, but most rely on motorized transport systems that emit greenhouse gases, CO ₂ emissions are widely known as global warming, the key factors causing climate change and ocean acidification. Although the amount of CO ₂ emitted by transporting one ton of cargo per mile is the most overwhelming vehicle in world trade, even though the ship is the most efficient means of transportation, the CO ₂ emissions are about the total amount of greenhouse gas emissions 3%. Therefore, by increasing the fuel efficiency of ships, the emission of greenhouse gases from industry can be greatly reduced.

In addition, the existing manual and semi-automatic methods of ship operation differ according to the crew's work level, and even in the case of the system developed by the semi-automatic method, the system can be applied only to the ship concerned. In order to do so, it is necessary to develop a software framework, which is a concept that provides a foundation for similar application development, requiring a software engineering approach.

SUMMARY OF THE INVENTION The present invention has been proposed in order to solve all of the above problems, and its object is to design and navigate an optimal operation route of a ship by applying energy efficiency operation index (EEOI) based on weather forecast, It is possible to reduce the carbon dioxide emission at the same time as it can reduce the emission of carbon dioxide, which can lead to economical navigation of the ship and prevent global warming. In addition, it is possible to re- And to provide an optimal economic navigation support system for a ship capable of reducing the cost.
