Ship energy saving method based on big data collection and analysis

Abstract

The invention discloses a ship energy saving method based on big data collection and analysis. The ship energy saving method comprises the steps that a database is established by collecting real-time data of main energy consumption equipment of a ship and real-time data of the navigation condition of the ship; the data of the energy consumption and the navigation condition of the ship are analyzed by a server, the energy consumption of the ship is evaluated, and the optimal trimming or rotating speed of the ship is recommended; the state of the ship is adjusted by ship handling personnel according to the optimal trimming or rotating speed; the data of the state and the energy consumption of the ship after adjustment are examined by virtue of a monitoring system and are compared with the data before adjustment, and if compared results are consistent, complete adjustment is fed back; if the compared results are inconsistent, error adjustment is fed back, and adjustment is performed again. According to the method, 2 to 3% of navigation fuel can be reduced.

Description

technical field [0001] The invention relates to a ship energy saving method, in particular to a ship energy saving method based on collecting and analyzing big data. Background technique [0002] Ship energy saving is an urgent need for my country to build a resource-saving and environment-friendly society. At present, the world's oil resources are increasingly scarce. In 2009, the remaining proven oil reserves in the world were 185.523 billion tons, which can only be exploited for 50 years. Natural gas and coal can only be exploited for more than 100 years, while the utilization of new energy is 52 years behind. At the same time, international oil prices have been rising steadily in recent years, while my country's annual crude oil consumption is 379 million tons, more than half of which depend on imports, and the situation of my country's oil resources is tense. In 2005, the total oil consumption of my country's transportation industry accounted for about 29.8% of the tot...

Problems solved by technology

[0004] Internationally, the purpose of reducing ship energy consumption is generally achieved by reducing ship speed and adjusting trim, which are set by the crew themselves based on experience, but there is no guarantee that the ship's energy saving will be optimized
