RALPH COFFMAN is a 2009 mobile offshore drilling unit. The Coast Guard has recorded 6 inspections since 2009, most recently in April 2018, along with 2 deficiencies.
Records from 2009 to 2018. Most recent: inspection, 30 April 2018.
The 6 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 8 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 Offshore class in Maury's sources begin in 1978.

Documentation record
Tonnage as PSIX records it10411 - Convention (Subpart B), Gross Ton 3123 - Convention (Subpart B), Net Ton
This hull's Official Number is not in the NVDC file dated 10 September 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.
Radio station licence
No FCC ship-station licence is recorded against this Official Number in the file of
6 September 2026. That is a fact about the licence file, not about the radio.
A report is not offered for this hull: Its record holds only 2 of the seven kinds of material a report is built from: inspections, deficiencies, operational controls, tow-unit appearances, casualty records, dimensions and documentation. That is a statement about the record, not about the vessel. Reports.

Ownership record
