NOBLE BLACKLION is a mobile offshore drilling unit. The Coast Guard has recorded 22 inspections since 2016, most recently in March 2025, along with 4 deficiencies and 2 operational controls.
Records from 2016 to 2025. Most recent: inspection, 11 March 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 Offshore 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.

The Coast Guard recorded this vessel and the following in the same
inspection activity — normally a tug and the barges in its tow. A recreational or
unclassed hull in the same activity is held and not published, so it does not appear
here: these lists are a floor, not a complete manifest.
