- vessel_history
- Finding
- The reproduced DANFS history identifies Oratamin as former Port Kent, Maritime Commission hull 451, built by Ira S. Bushey & Sons in Brooklyn, launched 23 December 1942, completed and taken over by the Navy 15 February 1943. It places her in San Juan Harbor through 1951, then in the Norfolk and Hampton Roads area, and gives the YTM-347 redesignation as February 1962.

- Limitations
- This is a reproduction of the DANFS text on a third-party site because the direct NHHC Oratamin entry could not be retrieved. It provides vessel history only, not equipment, asbestos content, individual exposure, or final disposition. The YTB-347 designation is in the entry heading but its effective date is not given.
