WFD RIG 450 is a 1999 mobile offshore drilling unit. The Coast Guard has recorded 21 inspections since 2016, most recently in July 2026, along with 8 deficiencies and 2 operational controls.
Records from 2016 to 2026. Most recent: inspection, 27 July 2026.
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.
The counts in the strip above are the same counts; this table splits the inspections by
the kind of activity 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.
Documentation record
Tonnage as PSIX records it7157 - Regulatory (Subpart C or D), Gross Ton 2147 - Regulatory (Subpart C or D), Net Ton
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.
Vessel history report
Every record for this hull, in one document — $299
What it gives that this page does not: the whole record in one
dated, citable document — every line with its Coast Guard activity id, the retrieval
date on the cover, built to print to PDF with its page breaks — that a surveyor can
attach and a lender can file. The same facts as this page, complete and in one file.
Every recorded inspection, 2016 to
2026 for this class, in one chronology · every deficiency, with system, dates
and resolution · operational controls imposed and removed · every name this
hull has been recorded under · the vessels it was inspected alongside, and when
· how its record compares with hulls of similar age and size, as a fact about the
population and never a judgement about this vessel.
A request, not a checkout: leave an email and Maury replies once, with
the dated document for this hull and a Stripe invoice for $299. Nothing is charged before
the document is in your hands.
