FLEX RANGER is a 2018 tank ship. The Coast Guard has recorded 14 inspections since 2018, most recently in May 2025, along with 1 deficiency and 2 operational controls.
Records from 2018 to 2025. Most recent: inspection, 27 May 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.
