# Speed Order

It is possible to change the instructed speed for each port call. This is a choice limited to the vessels speed and consumption combinations only depending on the leg being in ballast or laden.

* The dropdown shows both the speed and consumption
* Each speed will only affect the port call (leg) in question.

To add a speed for a vessel see the [vessel documentation](https://docs.dataloy.com/release-6.7/voyage-management-system/step-by-step-guides/vessels/vessel-speed-and-consumption-data).
