Both a captain and operator can request routing service. There might be distinction in this based on customer preference.

My voyage details have changed, how do I let DTN routing team know?
In case details change, fastest and easiest is to email the team via [email protected]. The team will follow up and update the voyage accordingly. If needed based on changes, a new route advice will be sent as soon as possible (for example destination change). If not needed directly, the update will be taken into account in
How can I contact the shipping operations team?
Our team is located both in Manilla and Utrecht, Netherlands and is available 24/7/365 via: Email: [email protected] T: +31 (0)20 8082 980″ We support short lines between our DTN routing team, master and operations team customer.
How come my route results shows ‘zig zag’ lines?
In this case it will probably the result of weather limits that have been set to ‘avoid’ instead of ‘warn’. It is likely that these limitations, especially when multiple limitations are set as a hard ‘avoid’ and limitations on especially beam waves, swell and wind. This can trigger the algorithm to ‘zigzag’, to avoid those
What result do I get when choosing the ‘ignore route network’?
If you request a route with all ‘ignore route network’ flags, no weather optimization is done and a ‘rumb-line’ route is created between the waypoints. Our advice (for true weather optimization) is to not use the “ignore route network”-flags during the long ocean crossings and only supply a departure and destination.
Am I able to set a vertex restriction?
Yes you are, you can find this under ‘restrictions’. Although you can specify a vertex restriction for the northern hemisphere and southern hemisphere, currently only the most restrictive one is applied for both north and south, our internal team is working on creating a separation of these items.
How can the outcome of the route result be different than expected when optimizing?
This can differ due to multiple variables, but in general take into account: At cost optimization, the route generated from the API is the most cost-efficient route as requested by the client, which is not necessarily the shortest.In these cases the result from the API is the most cost optimum option, despite being somewhat longer, taking
What does it mean that route request not able to calculate due reason ‘Blocked by the no go area XXX ?
The warning mentioned means that the vessel has to pass a conditional/no go area to get from the start WP towards the end WP. As this no go area normally is closed the routing API isn’t able to find a way between the two WP. The solution would be to open this conditional area (adding
Why is there no Wave Direction as part of the route response?
Waves always travel in the same direction that the wind is blowing. The elements used by the API with “Wave” in their naming pertain to wind waves, so you can infer that wind direction = wave direction as well with no further calculation required.
How do I know when the vessel is going too close towards land?
At shallow waters a route network is being used to navigate safely towards the harbor and berth. At open ocean (depending on the calculation type) weather optimization is applied. Based on the weather conditions, this could mean that the route will take advantage of more near-shore routes to avoid e.g. heavy waves.
