HISHI MARU NO.21 — Tanker · IMO 9109627

HISHI MARU NO.21 has not broadcast an AIS position for 207 days. The most recent broadcast placed it in the South China Sea, on 14 Apr 2026, 17:31 UTC. It was sailing from BRUNEI BAY to BINTULU. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

HISHI MARU NO.21 broadcasts MMSI 677083200 and is registered as IMO 9109627, with call sign 5IM932. 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.

HISHI MARU NO.21 is classified as a tanker vessel registered under the TZ flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full tanker fleet at /vessel-type/tanker and full TZ flag list at /flag/tz.
