Tracking and checking compliance of vessels

摘要

There are disclosed arrangements for tracking ships and other vessels to provide best estimate of vessel track, which can be used, for example, as part of a vessel compliance process or tool. Coordinate messages from different types of transceivers (AIS, L-band, etc.), located on board a vessel are used. A confidence level may be assigned to each coordinate message dependent on the identity of the indicated transceiver, the indicated geographical position, and other factors. Measures of performance of the transceivers may be generated and used in coordinating transceiver control.

1. A computer-implemented method of reporting to a user non-compliance of a vessel with a plurality of compliance rules, comprising:
screening a vessel by assessing compliance of the vessel with at least some of said compliance rules without reference to a current track of the vessel, and reporting resulting compliance issues to the user; monitoring, after completing the step of screening, compliance of the vessel in conjunction with a current track of the vessel, with at least some of said compliance rules, and reporting resulting compliance issues to the user; providing the user with access to a screening function for carrying out the screening step; permitting selection by the user of a screened vessel for voyage monitoring; and providing the user with access to a monitoring function for carrying out the monitoring step, and for reporting resulting compliance issues to the user.
