ROBERT S. PIERSON (DUPLICATE VESSEL/DO NOT USE)

Freight Ship · Bulk Carrier class · Built 1970s · USCG Great Lakes District (CGD-GL)

ROBERT S. PIERSON (DUPLICATE VESSEL/DO NOT USE) is a 1974 freight ship. The Coast Guard has recorded 144 inspections since 1985, most recently in May 2012, along with 56 deficiencies and 9 casualty investigations between 1993 and 2008.

Records from 1985 to 2012. Most recent: inspection, 11 May 2012.

This is an administrative record, not a vessel. The Coast Guard created this MISLE entry and then marked it as superseded — the name itself says which record it points to. It is kept here because it exists in the record and nothing is deleted, but the inspection history of the hull lives under the other entry.

FCC Universal Licensing System ship-station file of 6 September 2026, matched to this hull on its US Official Number. Status and dates are the file’s own. The licensee is not read from the file and is not shown. A lapsed licence’s MMSI is still the number the vessel transmitted under while it was valid.

Years with a record 28 calendar years (1985–2012)

The 144 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 14 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 11 September 2026 from PSIX. Every field on this page was recorded by the Coast Guard. Records for the Bulk Carrier class in Maury's sources begin in 1981.
