๐ข Analyzing Vessel Performance & Fuel Efficiency with AIS + Weather Data
1. Why Match AIS with Weather Data?
- AIS Data tells us when, where, and how fast a vessel has moved โ itโs essentially the vesselโs performance record.
- Weather Data reveals the conditions that surrounded the vessel โ wind, waves, and currents along the route.
- By combining the two, we can go beyond simple voyage tracking and quantify how the environment impacts performance.
๐ In short, AIS + Weather = the key tool to optimize vessel operations with data-driven insights.
2. Voyage Performance Analysis: Speed vs. Environment
Example 1: Wind Speed
- When wind speed exceeds 10 m/s, even with the same engine RPM, SOG (Speed Over Ground) drops by about 15%.
- This results in either extra fuel consumption or delayed arrival.
Example 2: Wave Height
- At wave heights over 3 meters, fuel consumption rises sharply.
- Older bulk carriers vs. modern eco-ships show significant efficiency differences under the same wave conditions.
Example 3: Ocean Currents
- On identical routes, sailing with a favorable current vs. against it can create a 20%+ gap in fuel efficiency.
- Historical AIS + weather data allows us to extract seasonal fuel efficiency patterns by route.
3. Fuel Optimization: What the Data Tells Us
Scenario Simulation
- Compare โsouthern summer routesโ vs. โnorthern winter routesโ and predict which yields better fuel performance.
Voyage Optimization
- Before departure, analyze historical AIS + Weather data to recommend the most efficient speed and route.
- Results: up to 2 days saved and 7% reduction in fuel costs on average.
Performance Benchmarking
- Compare vessel types and build years under identical conditions.
- Shipowners gain insights for investment and operational decisions.
4. Insights
- AIS alone: โThe vessel slowed down.โ
- AIS + Weather: โThe vessel slowed down because of strong headwinds, which increased fuel consumption.โ
๐ This combined approach enables: Optimized vessel performance, Lower fuel costs, Reduced carbon emissions, Higher schedule reliability
5. Conclusion โ The Future of Data-Driven Shipping
- The maritime industry is entering an era of data-driven decision-making, not just experience-based navigation.
- AIS + Weather analysis supports IMO regulatory compliance, enhances operational efficiency, and strengthens ESG strategies.
- Shipowners, charterers, and insurers alike can benefit from these insights.
๐ Data is not just a record โ itโs the compass for smarter, greener, and safer voyages.
With AIS + Weather data combined, shipping can chart a course toward sustainability and competitiveness.
