Question 1

Where is UJB right now?

Accepted Answer

UJB has not broadcast an AIS position for 133 days. The most recent broadcast placed it in the Yellow Sea, on 28 Apr 2026, 15:51 UTC. It was sailing from LANSHAN to NAMPO. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

Question 2

What are the identifiers for UJB?

Accepted Answer

UJB broadcasts MMSI 222333000. 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.

Question 3

How can I see the live position of UJB?

Accepted Answer

MarineRadar shows the latest AIS broadcast from UJB 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.

Question 4

How often is UJB's position updated?

Accepted Answer

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.

Question 5

What class is UJB?

Accepted Answer

The vessel's design class is inferred from its dimensions, gross tonnage and dead weight, all of which are listed in the Identity and Specifications panels on the vessel page.
