MERSEY — Tanker · IMO 9170420

MERSEY has not broadcast an AIS position for 5 days. The most recent broadcast placed it in the Baltic Sea, on 1 Nov 2026, 12:01 UTC. It was sailing from SKAGEN to ROSTOCK. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

MERSEY broadcasts MMSI 275541000 and is registered as IMO 9170420, with call sign YLSC. 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.

MERSEY is classified as a tanker vessel registered under the LV 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 LV flag list at /flag/lv.

MarineRadar shows the latest AIS broadcast from MERSEY above, with current position, course, speed, and navigation status. Tap "View on map" to centre the live tracker on the vessel and watch its movement update in real time. The same data is available offline-friendly in the iOS and Android apps.

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.

MERSEY is classed by LLOYD'S SHIPPING REGISTER, the classification society responsible for inspecting the vessel against safety, structural and operational rules. As a tanker, MERSEY 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. MERSEY has a gross tonnage of 2,760 GT.
