OCEAN BEST — Tanker · MMSI 440006970

OCEAN BEST has not broadcast an AIS position for 12 days. The most recent broadcast placed it in the Sea of Japan, on 27 Oct 2026, 23:28 UTC. It was sailing from JINHAE to BUSAN. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

OCEAN BEST broadcasts MMSI 440006970, with call sign 970838. 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.

OCEAN BEST 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.

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, OCEAN BEST 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.
