This record may be incomplete: the most recent inspection recorded for this vessel was 8 years ago. Maury shows what the Coast Guard recorded, not whether the vessel has been inspected since, is still in service, or what condition it is in. Coast Guard record current through 23 August 2026, retrieved 5 September 2026 from PSIX. Every field on this page was recorded by the Coast Guard. Records for the Tank Ship class in Maury's sources begin in 2016.

Every line above is a count of records the US Coast Guard wrote, or a date it recorded. A blank resolution means none was recorded in this data; it does not establish that a deficiency is outstanding. Years with a record are calendar years in which a record exists, not years in service. What Maury does not do.

Every line above is a field of the National Vessel Documentation Center's file as served by NOAA Fisheries, dated 10 August 2026, matched to this hull on its Official Number. Registered and ITC measurements are two systems and are never combined. One snapshot is held so far; documentation history begins with the next.

Vessel history report

A report is not offered for this hull. Its record holds only 2 of the seven kinds of material a report is built from: inspections, deficiencies, operational controls, tow-unit appearances, casualty records, dimensions and documentation. That is a statement about the record, not about the vessel. What a sparse-record report looks like.
