Key features
- Weather routing, considering wind, wind waves and swell, sea currents, water depth, tropical storms, and additional safety limits. Monthly climatology data is used when the voyage exceeds the weather forecast period.
- Optimization for a selected goal: Arrival time, constant speed, RPM, engine load, maximum daily profit, or overall cost reduction.
- Route and schedule alternatives are provided for comparison. You can also fetch an earlier voyage as a basis or define your own plan.
- The vessel’s performance is calculated using a proprietary NAPA performance model, which also supports vessels with wind-assisted propulsion.
- CII rating and CO2 emissions, fuel consumption, schedule, and costs are estimated for the voyage alternatives.
- Different fuel types and their properties and costs are accounted for, also considering the Emission Control Areas (ECAs).
- The proposed route is produced using safe navigable routes and is ECDIS compliant. Final verification for the safe passage will be done onboard with the latest ENC materials and Temporary and Preliminary Notices to Mariners.
- When en route, Voyage Monitoring automatically offers new route proposals as weather conditions change, and enables follow-up of execution of the voyage plan.
NAPA Voyage Optimization
How it works
- A module on the NAPA Fleet Intelligence platform, available both on a web browser and desktop application
- Onboard and on-shore tools for increased communication and awareness, boosting collaboration across voyage stakeholders
- User-friendly and proven features for daily voyage planning
- Weather routing for multiple voyage scenario simulations and comparisons on ETA, fuel cost, environmental performance, and safety
- High-accuracy performance model for all commercial ships, dynamically updated with data collected from vessels to reflect the current performance
- Available also as an API for 3rd party integration
NAPA Voyage Optimization
Benefits
- Operate fuel-efficiently without compromising safety
- Improve CII rating (Carbon Intensity Indicator)
- Decrease crew workload
- Improve voyage estimates by estimating fuel consumption with vessel-specific performance models and weather forecast
- Operate the whole voyage with optimum RPM profile while ensuring reaching the port by Laycan
- Arrive on the agreed ETA, and calculate the effect of ETA changes during the voyage for negotiating the demurrage rate of the delayed days and sharing of fuel reduction benefit between operator and charterer
- Increase Time Charter Equivalent earnings by making better deals, optimizing speed profile and route, and taking advantage of Virtual Arrival or Sea Traffic Management BIMCO clauses
- Increase efficiency in making and altering the voyage plans by improving communication possibilities with operator and crew
- Lower Scope 3 emissions
- Use the same performance model, environmental forecasts, and optimization algorithms on your own simulations and comparisons as the operator and the crew are using
- Decrease costs through improved scheduling, schedule adjustment processes, and improved route and speed profile optimization
- Reduce the risk of cargo loss, delays, or unnecessary expenditure with enhanced visibility into vessel operations and being actively involved in the voyage planning and execution

Routes
- Port to port connections
- Vessel draft and UKC requirements (Under Keel Clearance) considered in route finding
- Usage of channels automatically restricted by vessel size, or disabled manually by end-user
- Route optimized freely on open sea areas while respecting predefined fairways and traffic separation schemes
Overview of NAPA Voyage Optimization
Planning
- The latest vessel position updates automatically
- Port search to quickly find destinations or user-specified coordinates
- Open / Save your own plans or import & export from/to other formats (RTZ and proprietary ECDIS formats)
- Specify the primary speed control method for routing
- Route alternatives are found using selected target, such as daily profit maximization or overall cost reduction
- Channel restrictions are considered in the proposed routes (TSS, Suez Canal, Panama Canal, etc.)
- Expected delays from canal passing are automatically taken into account in ETA estimation

Alternatives
- Benchmark optimized option against the shortest, or a user-selected voyage
- Key performance indicators are shown in an easily comparable way
- Table view available for further details
- Compare different routes or the same route with different schedules
- Alternatives can be edited, while the effect on schedule and cost is immediately seen
- Save or share voyages for later use

Map and weather information
- All relevant parameters covered and considered in the optimization
- Global environmental data forecasts supplemented with locally higher resolution forecasts
- Map layers for the relevant geographic areas, such as Emission Control Areas or Piracy Risk Areas
- Global distribution of weather and map data ensures a good user experience
- Most important weather information clearly shown on all zoom levels
- Weather information and the ship’s predicted position always in sync
- Weather forecast can be shown to any selected point on the voyage timeline
- More details on weather conditions available on closer zoom levels
- Climatology database will be used beyond reliable forecast span (seasonal, sea area-specific conditions)
- Tropical storm forecast with predicted track
- Weather forecasts validated by the weather service provider and in our own studies (Read: The role of accurate nowcast data in ship performance analysis)

API access
API access is available for use cases such as:
- Onboard voyage planning application needing weather routing for the open sea passage of the voyage
- Voyage estimate calculations in a shipping ERP software needing accurate fuel consumption estimates, which consider the most probable weather conditions
- A shipping company’s internal KPIs needing calculations on what is the cost of anchorage time, how much could have been saved by from weather routing, or benchmarking the performance of different weather routing services
- A consultancy services for weather routing in need of more scalable IT tools for the fuel consumption estimates
- Free access is available for academic purposes; for example, evaluating emissions on different ship types and trading routes, evaluating the saving potential of different fuel-saving devices, or saving potential of improving the operational efficiency of ports by enhanced scheduling systems.
