DTN collaborated with MARIN (Maritime Research Institute Netherlands) to create vessel models for approximately 50 different vessel (sub) classes. These models include speed loss curves and wind and wave added resistance tables. DTN’s weather optimized routing algorithm uses these models to predict speed loss under the influence of wind and waves. Additionally, clients can provide

5. Service Deliverables and Service Level Agreement
Service deliverables Services that can be expected for all routing optimizations, in following order : Confirmation of service to master when receiving route request with clear instructions on type of service Validation of ETD Initial route advice 8-12 hours before ETD Daily update (optimizing) route advice (with fixed speed) until end of voyage. Route update is
6. Deliverables in Routing Process Explained
DTN Route Advice Click here to open a .pdf that will explain all the benefits and elements of the DTN route advice Daily Performance Indicator (DPI) A Daily Performance Indicator (DPI) provides a daily performance indication based on the noon report data provided. It is created automatically and contains, for example, loss in time, loss
7. Noon Reporting
Noon reports (normally sent daily at noon, hence the name) contain a standardized set of data relevant to a vessel, including: Voyage details Position details Observed weather details Remaining bunkers on board and respective consumptions The information can be used to: Track the vessel’s position Create route advices Assess the performance of the vessel and
1. Types of Routing Services
We have the following routing services:
Conditional Areas
Conditional areas can be set on default or voyage specific level. A limited number of no go areas are enabled by default. The most common areas are already added in the API and can be found here. This way you can find the area ID which can be inserted included in requests. In a voyage
RouteNetwork
DTN uses a RouteNetwork (in partnership with ChartWorld). The Route Network is a worldwide network of waypoints and leg-lines; it provides for tracks within Restricted Routing Areas and allows to implement own routing and optimization strategies in Unrestricted Routing Areas. Diverse Data Sources: It leverages a variety of sources: Bathymetry Charts Sailing Directions NavAreaWarnings T&P Notices
Implementation Advice by DTN
Our advice for true weather optimization is to only supply a departure (start) and destination (end) point for best optimization results. If only the departure (start) and destination (end) is provided, the algorithm will fully optimize the route. Provide accurate beam, LOA, and draft measurements of the vessel For safe and correct navigation output, it’s
Vessel Routing API Implementation
Introduction Below is a short example of how to implement the Vessel Routing API. This example is written for Node.js, but can easily be translated into other programming languages. The complete API specification can be found here. Technical Description To use the Vessel Routing API, you will take the following steps: Request a JWT access
