There are four types of JASREP Reports: Sailing Plan,
Position Report, Deviation Report and Final Report.
[SP] Sailing Plan
Sailing Plan is the basic information to estimate ship's
position, and it should be sent at the time when a ship participates in
this system. Reports should therefore be made when the ship departs from a
port within the service area or when the ship enters the area.
[PR] Position Report
Position Report is
the information to verify if ship's position input according to the Sailing
Plan in correct.
The 1st report
should therefore be sent at an optional time within 24 hours of departure
from a port or entering the service area, and then the reports should be
sent subsequently no less frequently than every 24 hours until Final
[DR] Deviation Report
is the information to be used for necessary correction of pre-reported
Sailing Plan when a ship deviates from the intended course due to change in
be sent whenever the Ship's position deviates 25 miles or more from the
original track, or the port of destination is changed, or other changes
occur with resultant change in Sailing Plan.
Final Report is
the information to terminate participation in the system. Accordingly,
reports should be sent prior to or on arrival at port, or when a ship
departed from the service area of the system.
