ARDMORE DEFENDER is a 2015 tank ship. The Coast Guard has recorded 11 inspections since 2016, most recently in January 2025, along with 2 deficiencies and 2 operational controls.
Records from 2016 to 2025. Most recent: inspection, 19 January 2025.
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.
