HARMONICS — Tanker · IMO 9799680

HARMONICS has not broadcast an AIS position for 3 days. The most recent broadcast placed it in the Indian Ocean, on 3 Nov 2026, 05:43 UTC. It was sailing from SINGAPORE to RICHARDS BAY. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

HARMONICS broadcasts MMSI 563077200 and is registered as IMO 9799680, with call sign 9V5487. 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.

HARMONICS is classified as a tanker vessel registered under the SG 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 SG flag list at /flag/sg.

AIS transponders broadcast position every 2 seconds when underway at high speed and up to every 3 minutes at anchor. The position you see refreshes whenever the ship is in range of a coastal AIS receiver or a satellite pass — typically seconds in coastal waters and minutes offshore.

As a tanker, HARMONICS sits in the same design class as the other tankers listed in the Similar Vessels section of the vessel page, or in the full tanker directory at /vessel-type/tanker. HARMONICS has a gross tonnage of 22,988 GT.
