About STEEL HARBOR
STEEL HARBOR is a Japan-flagged Multi-Purpose registered under IMO 9256738 (MMSI 736411246) and currently associated with the Port of Kolkata, India. 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 101 metres in length overall by 16 metres in beam, with a gross tonnage of 35,310 GT and a deadweight of 37,168 tonnes.
The vessel is shown as moored, indicating she is secured at a berth or designated mooring with engines on standby and cargo operations either underway or completed. Her current declared estimated time of arrival is Apr 30, 2026 10:42 UTC, although ETAs are routinely revised in transit to reflect weather, routeing and pilot scheduling. She was built in 1998. 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 (9256738) 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 101 metres length overall by 16 metres beam, with 35,310 gross tonnage and 37,168 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.
