DC IV is a 2000 offshore supply vessel. The Coast Guard has recorded 5 inspections since 2016, most recently in January 2018, along with 11 deficiencies — 2 with no resolution recorded —, 1 operational control and 4 casualty investigations between 2006 and 2009.
Records from 2006 to 2018. Most recent: inspection, 25 January 2018.
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 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.

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.

Ownership record

Vessel Documentation Center, files it here with its date, and every reader of this page gets it.
