Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

NIKKO MARU NO.6 broadcasts MMSI 431400324 and is registered as IMO 9084906, with call sign JJ3817. The MMSI is the radio identifier used by AIS; the IMO number stays with the ship for life and does not change with re-flagging or sale.
