HORIZON THETIS is a 2009 tank ship. The Coast Guard has recorded 17 inspections since 2016, most recently in July 2023, along with 3 deficiencies and 4 operational controls.
Records from 2016 to 2023. Most recent: inspection, 27 July 2023.
This record may be incomplete: the most recent inspection recorded for this vessel was 3 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.

This hull's Official Number is not in the NVDC file dated 10 August 2026 as served by NOAA Fisheries, so no documentation record is shown. Absence from that file is a fact about the file, not about the hull.
