Question 1

Where is GEMMA right now?

Accepted Answer

GEMMA has not broadcast an AIS position for 406 days. The most recent broadcast placed it in the Caribbean Sea, on 28 Jun 2025, 03:41 UTC. It was sailing from SINGAPORE to SINGAPORE. 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 GEMMA?

Accepted Answer

GEMMA broadcasts MMSI 668116220 and is registered as IMO 9167564, with call sign S9A22. 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

What type of ship is GEMMA?

Accepted Answer

GEMMA is classified as a tanker vessel registered under the ST 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 ST flag list at /flag/st.

Question 4

How can I see the live position of GEMMA?

Question 5

How often is GEMMA'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 6

What class is GEMMA?

Accepted Answer

As a tanker, GEMMA 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.
