- Finding type
- asbestos_application
- Finding
- Class/design documentation: the Chimo-class ACMs were built to the Army's 188-foot twin-screw, steel, steam-propelled mine-planter design (Marietta Mfg. hulls 474-489, MP-1 through MP-16); class machinery was Skinner Unaflow reciprocating steam engines (1,200 hp, 2 screws). A 1942-built reciprocating steam plant of this type is era-consistent with asbestos-containing boiler insulation, steam-line lagging, flange/valve gaskets, and machinery packing.

- Construction trades (Marietta Mfg., Point Pleasant, 1941-42); ship's engineering crew (Army, Navy, USCG periods)
- Limitations
- Class/design-level documentation, not a hull record - the source does not state 'asbestos' content for any hull, and asbestos presence aboard this hull is era inference, not ship-proven. Does not establish quantity, location, condition, individual exposure, or causation.

- Finding type
- asbestos_application
- Finding
- Peer-reviewed historical study documents that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during WWII - the era and program under which this 1942 steam-propelled hull was built - and that wartime demand drove unprecedented asbestos utilization in naval and merchant construction.

- Finding
- DANFS record for Barbican (ACM-5): built in 1942 by Marietta Manufacturing Co., Point Pleasant, W. Va., as Colonel George Armistead for the Army Coast Artillery Corps; transferred to the Navy 6 January 1945; converted to an auxiliary minelayer at Charleston Navy Yard; commissioned 24 March 1945 (LCDR A. Anderson, Jr.); reported to the Pacific Fleet but arrived too late for combat - departed Pearl Harbor 17 August 1945, arrived Saipan 20 September; operated between the Marianas and Ryukyus as tender and operational headquarters for a YMS squadron; departed Okinawa 24 October for Sasebo, Japan; occupation duty until 24 February 1946; decommissioned 12 June 1946 and loaned to the Coast Guard the same day. DANFS data line: dp. 880; l. 188'2"; b. 37'; dr. 12'6"; s. 12.6 k.; cpl. 69; a. 1 40mm; cl. Chimo.

- Limitations
- Establishes identity, builder, Navy service chronology, and the 1945 Charleston Navy Yard conversion event. Contains no asbestos, insulation-material, or condition information; supports no asbestos claim. The 880-ton DANFS figure is light displacement - Shipscribe class data gives 880 light / 1,320 full, reconciling the apparent conflict with the 1,300-1,323-ton figures in other sources.

- Shipscribe class record (compiled from Navy records): ACM-5 Barbican - ex-Army COL. GEORGE ARMISTEAD (MP-3, completed 23 Aug 42); acquired by Navy 6 Jan 1945; converted by the Charleston, S.C. Navy Yard 6 Jan-25 Mar 45; commissioned 24 Mar 45; decommissioned 12 Jun 46; stricken 19 Jul 46; to USCG as buoy tender IVY (WAGL/WLB-329, in commission 21 Apr 47-26 Nov 69); merchant BALBOA (1977), SEA FOX (1981). Class notes: the Army ordered sixteen 188-ft twin-screw steam mine planters from Marietta Mfg. (hulls 474-489, MP-1 to MP-16) under 1941 contracts; the Navy acquired three in 1944 and five more (incl. this hull) under the 30 Dec 44 CNO directive for conversion to YMS minesweeper tenders/flagships; six of the eight went to the Coast Guard postwar.

- Authoritative compiled record of dates and custody; contains no asbestos or materials information. Post-1969 merchant names conflict with other secondary sources (Maria Jose 1977 per NavalCoverMuseum) - carried in gaps, not asserted as resolved. 'Completed 23 Aug 42' conflicts with the December 1942 delivery date in secondary sources - logged in gaps.

M/Vs Alan Seeger and Audrey (1951), M/V Paul T.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or docketed case naming the hull (as Barbican, ACM-5, Colonel George Armistead, or USCGC Ivy) was found in the public sources searched (see search_ledger). The hull's Navy and Coast Guard records establish only its construction, conversion, machinery, and service chronology.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1942 steam auxiliary is era-consistent with asbestos-containing insulation. The CourtListener API was rate-limited (125/day cap reached machine-wide; reset ~7h) so the litigation sweep is a gap, not a completed negative - logged as blocked in the ledger. Does not establish presence or absence; does not establish or defeat any exposure claim or legal eligibility.
