About DIAMOND NEPTUNE
DIAMOND NEPTUNE is a Bahamas-flagged Multi-Purpose registered under IMO 9430140 (MMSI 641787349) and currently associated with the Port of Port-Gentil, Gabon. Vessels in this class belong to the broader multi-purpose terminal family — operationally that means cargo handling and voyage planning are dominated by a flexible mix of general cargo vessels, project carriers, heavy-lift ships, and break-bulk tonnage. Mobile harbour cranes, mafi trailers, and conventional slings handle non-containerised steel, machinery, forestry products, and oversized industrial components. She measures 129 metres in length overall by 19 metres in beam, with a gross tonnage of 109,805 GT and a deadweight of 171,570 tonnes.
The vessel is currently shown as underway, meaning her AIS transponder is reporting a course and speed consistent with passage between port calls. Her current declared estimated time of arrival is May 6, 2026 22:42 UTC, although ETAs are routinely revised in transit to reflect weather, routeing and pilot scheduling. She was built in 2022. The vessel is registered with the International Maritime Organization, whose database of registered ships and the conventions governing their operation is published at the IMO conventions library.
IMO numbers are issued by IHS Markit on behalf of the International Maritime Organization and remain attached to the hull for the lifetime of the vessel â they do not change with sale, re-flagging, or rename. MMSI numbers, in contrast, are issued by the flag state’s telecommunications administration and identify the vessel’s radio installation; an MMSI changes when a vessel changes flag. When researching an individual ship across historical records â particularly for incident investigation, port state inspection history, or insurance claims â the IMO number (9430140) is the stable identifier to anchor the search on, while the MMSI is the right key for AIS reception logs and VHF radio licensing records.
The vessel’s declared dimensions of 129 metres length overall by 19 metres beam, with 109,805 gross tonnage and 171,570 tonnes deadweight, place her in a specific size class within the global multi-purpose fleet. These particulars determine which port berths she can use, which canals she can transit (Panama Canal locks, Suez Canal draught, the Strait of Malacca’s Malaccamax constraint), and which terminals around the world have the cranes and yard plant to work her efficiently.
