Years with a record 8 calendar years (2007–2020)

The 9 inspections in the strip above, split by the kind of activity the US Coast Guard recorded. Years with a record are calendar years in which a record exists, not years in service. What Maury does not do.

This record may be incomplete: the most recent inspection recorded for this vessel was 6 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 13 September 2026, retrieved 18 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 1980.
