IEC 63173-1:2021 The voyage plan is a key element of a vessel's voyage and can be used to optimize safety and processes, as well as for the interaction of participants and stakeholders.
The core element of the voyage plan is the route.
The exchange of routes (whether it be between ship-to-ship, ship-to-shore or shore-to-shore) may improve
– situational awareness,
– reduction in the number of accidents and incidents (by proactively de-conflicting routes),
– resource utilization by knowing the intentions of other actors,
– secured passages by knowing the intentions of other actors,
– predictability of arrivals and departures by early information sharing,
– planning for involved actors leading to reduced idle time for resources, and
– just-in-time operations by enabling stakeholders and service providers to be efficiently organized for handling vessel movements, port resources, and hinterland connections.
