GAS KUMAI — Tanker · IMO 9196333

GAS KUMAI has not broadcast an AIS position for 36 days. The most recent broadcast placed it in the Java Sea, on 2 Oct 2026, 02:41 UTC. It was sailing from SAMPIT to SEMARANG. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

GAS KUMAI broadcasts MMSI 525501973 and is registered as IMO 9196333, with call sign YDCB3. 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.

GAS KUMAI is classified as a tanker vessel registered under the ID 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 ID flag list at /flag/id.

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.

GAS KUMAI is classed by KOREAN SHIPPING REGISTER, the classification society responsible for inspecting the vessel against safety, structural and operational rules. As a tanker, GAS KUMAI 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.
