About STEEL HARBOR
STEEL HARBOR is a France-flagged LNG Carrier registered under IMO 9108889 (MMSI 330949798) and currently associated with the Port of Houston, United States. Vessels in this class belong to the broader liquid bulk terminal family — operationally that means cargo handling and voyage planning are dominated by crude tankers, product tankers, chemical parcel tankers, LNG and LPG carriers. Operations are characterised by dedicated jetties or single-point moorings (SPMs), articulated marine loading arms, vapour return systems, and stringent fire-fighting and oil-spill response protocols. Custody transfer relies on flow meters and tank-gauging systems calibrated to OIML and API standards. She measures 262 metres in length overall by 42 metres in beam, with a gross tonnage of 245,609 GT and a deadweight of 396,144 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 5, 2026 18:42 UTC, although ETAs are routinely revised in transit to reflect weather, routeing and pilot scheduling. She was built in 2014. 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 (9108889) 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 262 metres length overall by 42 metres beam, with 245,609 gross tonnage and 396,144 tonnes deadweight, place her in a specific size class within the global lng carrier 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.
