Dataloy VMS calculates and displays the shortest route for the entered rotation in the Ports (or Port Rotation) field, automatically inserting, where needed, available default routing points. The Voyage Estimate module allows for an unlimited number of port calls, routing points etc. to be added to a voyage calculation. The Ports (or Port Rotation) field lists by default load ports and thereafter discharge ports in the order they were entered irrelevant of actual voyage voyage pattern order. Each entered port call will displays as individual rows, each row containing relevant port call data. Additional Additional (or extra) ports are any type of port call aside from load and discharge ports, for example bunkering, and unlike load/discharge ports are not dependent on a cargo, but only linked to the voyage.
Routing points are also used when creating voyage rotation patterns and can be defined as specific locations that a vessels pass through when en route between port vessels pass through when en route between port calls. They are linked to the voyage only, and are not dependent on a specific cargo but can be entered together with (in the same or in different) cargo specific rotations for simplicity. Canals are routing points that will by default show as a separate port call in the port rotation in order to address the time and cost involved with canal passages directly to the canal. The canal time and cost has a direct impact on the result and length of a voyage. Each routing point (including canals) is defined by a unique code and name.
