Embodiment 1

[0221] Example 1: Minimum fuel consumption during the voyage

[0222] When the target of the program optimization is the minimum total fuel consumption of the ship voyage, at first the real ship monitoring data of the target ship (merchant ship in the embodiment of the present invention) is used as the analysis basis to analyze the speed of the ship under the conditions of weather data and no weather data. The relationship between the main engine speed and the speed of the main engine is established according to the model establishment process respectively according to the main engine speed-ship speed model without meteorological data and the main engine speed-ship speed model without meteorological data; then analyze the fuel consumption of the target ship without meteorological data The relationship between the fuel consumption of the target ship and the speed of the main engine and the relationship between the fuel consumption of the target ship and the speed of the main eng...

Embodiment 2

[0223] Embodiment 2: The fuel consumption of the voyage within the specified voyage is the minimum

[0224] When the goal of program optimization is to minimize the fuel consumption of the ship during the voyage, at first the real ship monitoring data of the target ship (the merchant ship in the embodiment of the invention) is used as the analysis basis, and the analysis is carried out under the conditions of weather data and no weather data. , the relationship between the speed of the ship and the speed of the main engine, respectively according to the model building process to establish the main engine speed-ship speed model without meteorological data and the main engine speed-ship speed model without meteorological data; then analyze the target ship without meteorological data The relationship between the fuel consumption of the ship and the speed of the main engine and the relationship between the fuel consumption of the target ship and the speed of the main engine and the...

Embodiment 3

[0225] Example 3: The shortest voyage

[0226] When the target of program optimization is the shortest voyage period of the ship, at first the real ship monitoring data of the target ship (being a merchant ship in the embodiment of the present invention) is used as the analysis basis, and the relationship between the ship's speed and the main engine is analyzed under the conditions of weather data and no weather data. The relationship between the rotating speeds is to establish the main engine speed-ship speed model without meteorological data and the main engine speed-ship speed model without meteorological data respectively according to the model establishment process; The relationship between the speed of rotation and the relationship between the fuel consumption of the target ship and the speed of the main engine and the weather data in the case of meteorological data, the fuel consumption prediction model of the ship without meteorological data and the fuel consumption pre...

Abstract

The invention relates to the field of ship shipping, in particular to a commercial ship navigational speed optimization method, which is characterized by comprising the following steps of: 1, acquiring real ship monitoring data, voyage data, meteorological data and route data of a commercial ship; 2, respectively establishing relation models of the host rotating speed and the ship navigational speed when the meteorological data exists and when the meteorological data does not exist; 3, respectively establishing oil consumption prediction models with meteorological data and without meteorological data; 4, processing the route data to obtain route segment data; 5, applying the leg data to the relation model of the main engine rotating speed and the ship navigational speed and the oil consumption prediction model; 6, establishing a commercial ship single-voyage total fuel consumption model in combination with the navigational speed planning range and the meteorological data; and 7, optimizing the navigational speed according to different optimization targets to obtain an optimal optimization scheme. The ship navigational speed can be optimized based on different optimization targets, and the navigational speed optimization result is more accurate and reliable.

Description

technical field [0001] The invention relates to the field of ship shipping, in particular to a method for optimizing the speed of a merchant ship. Background technique [0002] According to the requirements for speed optimization in the "Smart Ship Specifications" issued by China Classification Society (CCS) in 2015: [0003] (1) According to voyage planning, fuel consumption, comprehensive economic benefit analysis, etc., it can provide speed optimization schemes based on different objectives. [0004] (2) The speed optimization analysis should be based on the ship's navigation data, combined with the results of the voyage plan, route characteristics, ship efficiency, fuel consumption evaluation, and navigation cost accounting analysis to form a speed optimization plan. [0005] To optimize the speed of the ship, it is necessary to comprehensively consider the ship's voyage period, the total fuel consumption of the ship, and the comprehensive economic benefits of the voyag...
