SYLSNES — Tug · MMSI 257002160

SYLSNES has not broadcast an AIS position for 4 days. The most recent broadcast placed it in the Norwegian Sea, on 2 Nov 2026, 12:05 UTC. It was sailing from GROVFJORD to GRYLLEFJORD. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

SYLSNES broadcasts MMSI 257002160, with call sign LK9721. 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.

SYLSNES is classified as a tug vessel registered under the NO flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full tug fleet at /vessel-type/tug-pilot-vessel and full NO flag list at /flag/no.

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.

As a tug, SYLSNES sits in the same design class as the other tugs listed in the Similar Vessels section of the vessel page, or in the full tug directory at /vessel-type/tug-pilot-vessel.
