STOLT EFFORT — Tanker · IMO 9178202

STOLT EFFORT has not broadcast an AIS position for 3 days. The most recent broadcast placed it in the North Atlantic Ocean, on 4 Nov 2026, 07:58 UTC. It was sailing from ANTWERP to NEW ORLEANS. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

STOLT EFFORT broadcasts MMSI 319445000 and is registered as IMO 9178202, with call sign ZCSP6. 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.

STOLT EFFORT is classified as a tanker vessel registered under the KY 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 KY flag list at /flag/ky.
