About SPIRIT NEPTUNE
SPIRIT NEPTUNE is a Panama-flagged Container Ship registered under IMO 9617322 (MMSI 327821179) and currently associated with the Port of Puerto Cortes, Honduras. Vessels in this class belong to the broader container terminal family — operationally that means cargo handling and voyage planning are dominated by cellular container vessels equipped with twin-twenty cell guides, ranging from feeder ships of 1,000–3,000 TEU up through neo-Panamax and ultra-large container vessels exceeding 18,000 TEU. Quayside operations rely on ship-to-shore (STS) gantry cranes with outreach capable of handling 22-row-wide vessels, supported by RTGs, RMGs, or straddle carriers in the yard, and reefer plug-in capacity for refrigerated containers. She measures 218 metres in length overall by 37 metres in beam, with a gross tonnage of 396,363 GT and a deadweight of 435,564 tonnes.
The vessel is shown as arriving, meaning her declared destination matches the port currently associated with her track and her ETA is within the active reporting window. Her current declared estimated time of arrival is May 4, 2026 13:42 UTC, although ETAs are routinely revised in transit to reflect weather, routeing and pilot scheduling. She was built in 2010. 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 (9617322) 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 218 metres length overall by 37 metres beam, with 396,363 gross tonnage and 435,564 tonnes deadweight, place her in a specific size class within the global container ship 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.
