Benefits of technology

The technical feature described by this new innovation allows for better control over how much fuel can be used on ships without sacrificing their efficiency or performance level.

Problems solved by technology

This patented problem addressed in this patents relates to improving efficiency when designing marine vessels with improved performance or reducing their environmental footprint through efficient use of resources such as fuel. Current analyzes require complex calculations involving multiple factors like vessel size, boat speed, cargo load weight, etc., which makes it difficult to identify potential issues related to these variables without actually measuring them accurately.

Embodiment 1

[0033]1. Data collection: Obtain the ship's water-to-water speed, ship's speed to the ground, real-time speed of the ship's main engine, instantaneous fuel consumption of the ship's main engine and surplus water depth.

[0034] 2. Establish a mathematical model: under the condition that the ship is in sufficient water depth, on the same time axis, establish a mathematical model between the real-time speed of the ship's main engine and the ship's water-facing speed, and establish the relationship between the real-time speed of the ship's main engine and the instantaneous fuel consumption of the ship's main engine. mathematical model.

[0035] 3. Analysis and calculation: It is to analyze and calculate the established mathematical model under the conditions of different water flow rates and different main engine speeds, and obtain the predicted value of the ship's fuel consumption per kilometer to the ground corresponding to the ship under different conditions.

Embodiment 2

[0038] On the basis of method embodiment 1, a fuel consumption judging program is set after the steps are analyzed and calculated. In the fuel consumption judging program, the instantaneous fuel consumption of the main engine and the "reminder value" and "alarm value" of the ship's fuel consumption per ground kilometer are set in advance. During this period, if the result of step analysis and calculation is higher than the "reminder value" or "alarm value", the driver will be informed in a reminder or alarm mode that the operation method needs to be corrected.

Embodiment 3-4

[0040] On the basis of the method embodiment 1-2, after the analysis and calculation, a fault judgment program is set, and in the fault judgment program, the mathematical model between the main engine speed and the instantaneous fuel consumption of the main engine under the normal technical state is set in advance as a reference model; During this period, the mathematical model between the main engine speed and the instantaneous fuel consumption of the main engine in the results of step analysis and calculation is also established as a real-time model, and the real-time model is compared with the reference model. When the curve difference exceeds the set value, an alarm will be used to remind the technical status of the ship that there is a problem.
