Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies face challenges in optimizing the balance between fuel cost, emissions, and trip time for marine vessels, as the relationship between vessel speed, trip time, and fuel usage is non-intuitive and nonlinear, requiring a balance that is difficult to achieve with existing methods.
Innovation Solution
The implementation of edge computing and machine learning models that predict vessel speed and fuel consumption based on engine RPM and load, incorporating geographic and environmental factors, allowing for real-time optimization of trip time and cost while minimizing emissions.

Engineering Contradiction Analysis
1Productivity
If vessel speed is increased to reduce trip time, then productivity improves, but fuel consumption and emissions increase
Solution Approach 1:
The system dynamically adjusts vessel speed based on real-time conditions (weather, traffic, vessel state) rather than maintaining a fixed speed. The machine learning model continuously optimizes speed profiles during the voyage, allowing the vessel to adapt its operational parameters to balance trip time and fuel consumption under varying conditions.
Solution Approach 2:
The system changes operational parameters (speed, engine RPM, propeller pitch) based on predicted outcomes from the machine learning model. By adjusting these parameters in response to environmental and operational conditions, the system optimizes the trade-off between productivity and energy consumption.
2Productivity
If vessel speed is increased to reduce trip time, then productivity improves, but emissions increase
Solution Approach 1:
The system implements a feedback loop where the machine learning model continuously monitors actual emissions and operational data, compares them with predictions, and adjusts speed recommendations accordingly. This closed-loop control enables the system to optimize the balance between productivity and emissions reduction based on real-time performance.
3Use of energy by moving object
If fuel consumption is reduced to lower cost and emissions, then energy efficiency improves, but trip time increases
Solution Approach 1:
The system performs preliminary optimization by predicting the optimal speed profile before the vessel departs or during early stages of the voyage. The machine learning model uses historical data and environmental forecasts to pre-calculate speed recommendations that minimize fuel consumption while meeting delivery time constraints, allowing operators to plan ahead rather than reactively adjust.
4Productivity
If machine learning models are implemented for real-time optimization, then operational efficiency improves, but device complexity increases
Solution Approach 1:
The machine learning system is segmented into modular components: data collection modules, prediction models, optimization algorithms, and user interface modules. This segmentation allows the complex system to be developed, deployed, and maintained in manageable parts, reducing the practical complexity despite the advanced functionality provided.
