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

Embodiment Construction

[0020] The present invention will be further described below in conjunction with specific embodiment:

[0021] A ship energy-saving method based on collecting and analyzing big data, comprising the following steps:

[0022] (1) Collect the real-time data of the ship's main energy-consuming equipment and the real-time data of the ship's navigation status. The real-time data of the main energy-consuming equipment includes the power, pressure, temperature, and fuel consumption parameters of the ship's main engine and auxiliary equipment. The pressure and temperature of the host and auxiliary equipment are measured by installing sensors on the host and auxiliary equipment; the power of the host and auxiliary equipment is measured by installing a horsepower meter on its shaft; fuel consumption is measured by Measured by installing a flow meter on the oil pipe of the equipment. These signals are transmitted to the cabin monitoring system.

[0023] The real-time data of the ship's ...

Abstract

The invention discloses a ship energy-saving method based on collecting and analyzing big data. A database is established by collecting real-time data of main energy-consuming equipment and real-time data of the ship's navigation status; Evaluate the energy consumption and recommend the optimal ship trim or speed; ship operators adjust the ship status according to the optimal trim or speed plan; check the adjusted ship status and energy consumption data through the monitoring system, which is different from the pre-adjustment The data is compared. If the comparison results are consistent, the feedback adjustment is completed. If the comparison results are inconsistent, there is an error in the feedback adjustment and re-adjustment. This method can reduce voyage fuel by 2‑3%.

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...
