A computer-implemented method of tracking vessel movement which comprises receiving a first vessel data message comprising a first vessel identifier, the first vessel data message having been transmitted at a first time and being associated with a first position; and receiving a second vessel data message comprising a second vessel identifier, the second vessel data message having been transmitted at a second time and being associated with a second position. The method also comprises determining if the first vessel identifier and the second vessel identifier are related. If the first vessel identifier and the second vessel identifier are related, a speed required for a vessel to have moved from the first position to the second position is determined; which is then determined if the speed is below a speed threshold; and if the speed is below the speed threshold, the first position is associated with the second position.
