CHEM SIRIUS — Tanker · IMO 9558397

CHEM SIRIUS has not broadcast an AIS position for 5 days. The most recent broadcast placed it in the Caribbean Sea, on 2 Nov 2026, 18:46 UTC. It was sailing from LA ROMANA to ANTOING. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

CHEM SIRIUS broadcasts MMSI 636017165 and is registered as IMO 9558397, with call sign D5JP4. 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.

CHEM SIRIUS is classified as a tanker vessel registered under the LR 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 LR flag list at /flag/lr.

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.

CHEM SIRIUS is classed by NIPPON KAIJI KYOKAI (NKK), the classification society responsible for inspecting the vessel against safety, structural and operational rules. As a tanker, CHEM SIRIUS 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.
