JBU SAPPHIRE — Tanker · IMO 9412725

JBU SAPPHIRE has not broadcast an AIS position for 181 days. The most recent broadcast placed it in the South China Sea, on 9 May 2026, 13:30 UTC. It was sailing from SINGAPORE to GENERAL SANTOS. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

JBU SAPPHIRE broadcasts MMSI 440122000 and is registered as IMO 9412725, with call sign D7FB. 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.

JBU SAPPHIRE is classified as a tanker vessel registered under the KR 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 KR flag list at /flag/kr.
