SEA1 SAPPHIRE — Cargo · IMO 9417696

SEA1 SAPPHIRE has not broadcast an AIS position for 8 days. The most recent broadcast placed it in the North Pacific Ocean, on 29 Oct 2026, 06:05 UTC. It was sailing from KEELUNG to KEELUNG. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

SEA1 SAPPHIRE broadcasts MMSI 257544000 and is registered as IMO 9417696, with call sign LDTO3. 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.

SEA1 SAPPHIRE is classified as a cargo vessel registered under the NO flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full cargo fleet at /vessel-type/cargo and full NO flag list at /flag/no.
