- Finding
- The official Naval Vessel Register entry for IX-534 identifies the craft as 'NO NAME (IX 534)', Unclassified Miscellaneous, '(ex - ABSD 1B, AFDB 1B)' - i.e., Section B of ABSD-1/AFDB-1 (Artisan). UIC 05001; delivery date 1943-07-01; stricken 2007-01-04; status 'disposed of, sold by defense reutilization and marketing service (DRMS) for reuse/conversion' effective 2007-09-17; custodian category 'schools, organizations and private enterprises'; record last updated 2007-11-26.

- Finding
- DANFS documents the parent dock: ABSD-1, a 10-section non-self-propelled floating drydock (38,500 t light, 927 ft, 256 ft beam, 9 ft light/78 ft flooded draft, 133 ft 7 in clear inside width, 90,000-ton lift, complement 690), sections built 1942-43 by Everett Shipbuilding (Everett WA), Chicago Bridge & Iron (Eureka CA), Pollack-Stockton Shipbuilding (Stockton CA), and Chicago Bridge & Iron (Morgan City LA); commissioned 1943-05-10 at Everett, Capt. Andrew R. Mack. Towed in convoys to Espiritu Santo; during assembly 1943-11-02 one section sank, drowning 13 crew; worked as an 8-section dock until April 1944 when 'her remaining section was combined with another from ABSD-2' to reach ten sections. Served Espiritu Santo to mid-April 1945; reassembled at Manicani Bay, Samar, by mid-September 1945; worked through February 1946; decommissioned 1946-05-31; reclassified AFDB-1 August 1946; Pearl Harbor reserve; recommissioned 1951-06-02; Guam, ready 1952-03; out of commission and in reserve by January 1955; five sections to Subic Bay, in service 1970-11-17; named Artisan 1979-06-07; out of service and struck October 1986; reinstated March 1987.

- Limitations
- Documents the parent dock, not IX-534 by name - the section's presence at each station is not itemized. Physical-provenance caveat: an ABSD-1 section sank during assembly 1943-11-03-era and an ABSD-2-built section completed the dock in April 1944; consulted sources do not identify which section sank, so the steel carrying designation '1B' could theoretically be the ABSD-2-donated section - the NVR designation 'ABSD 1B' is carried regardless. DANFS 'back in reserve by January 1955' vs NavSource photo documentation of the decommissioning crew 1956-11-01 - unreconciled. No asbestos or material content.

- NavSource and NavalCoverMuseum concur with the NVR on the section-level disposition of AFDB-1 effective 1987-03-01: sections A, G, H, I sold for scrapping by DRMS; Section B redesignated Unclassified Miscellaneous IX-534 and laid up at the Naval Inactive Ships On-site Maintenance Office (NISMF), Pearl Harbor; Section E laid up at NISMF Pearl Harbor; Section F disposed of as a target; Section C redesignated IX-525 (Pacific Missile Range Facility, Kekaha, HI); Section D redesignated IX-521 (struck 2006-04-26, NISMF Pearl Harbor). NavalCoverMuseum records IX-534 stricken from the Naval Register 2007-01-04, matching the NVR.

[5]Correction record: Wikipedia IX-list entry 'USS IX-534, ex-ABSD-2, ex-AFDB-2, section B' vs Naval Vessel Register 'NO NAME (IX 534) (ex - ABSD 1B, AFDB 1B)' and NavSource AFDB-2 section-B disposition [other_primary]

- Finding type
- vessel_history
- Finding
- The Wikipedia List of unclassified miscellaneous vessels entry calls IX-534 'ex-ABSD-2, ex-AFDB-2, section B'. This is contradicted by (a) the NVR hull record, which reads 'ex - ABSD 1B, AFDB 1B'; (b) NavSource's IX index, 'IX-534 ex Artisan (AFDB-1) Section 1B'; (c) NavalCoverMuseum's ABSD-1 record; and (d) AFDB-2's own disposition - its Section B was 'disposed of in support of Fleet training exercise' 1990-07-13 (NavSource ABSD-2 record; Wikipedia's own AFDB-2 article agrees), so AFDB-2 Section B cannot be IX-534. The IX-list attribution is treated as a copy artifact from the adjacent AFDB-2-derived rows (IX-522, IX-524, IX-535). Carried: ex-ABSD-1/AFDB-1 Section B.

- Limitations
- Resolves a secondary-source conflict using the primary register record plus the independently documented disposal of AFDB-2 Section B. The residual physical-provenance caveat (April 1944 incorporation of an ABSD-2-built section into ABSD-1's dock) is recorded in ev-uss-ix-534-02 and gaps - designation '1B' is authoritative even if the steel's original yard is ambiguous.

- Finding type
- historical_record
- Finding
- A secondary per-section ship list attributes AFDB-1 section 1B (IX-534) to the Everett-Pacific yard, Everett WA, completed May 1943 (3,850 t, 93 ft per section), and records 'Reclassified IX 534, in service 2008 as Dock #5 in Portland OR'; the same list records IX-521 (1D), AFDB-1 section 1E, and AFDB-2 sections 2E and 2I in the same Portland Dock #5 in 2007-08. Independently, shipbuildinghistory.com and Vigor Marine document the Swan Island shipyard, Portland OR (Port of Portland repair yard until 1999, then Cascade General, now Vigor) operating a 'Drydock #5'. The composite-dock reuse is consistent with the NVR disposal category 'sold by DRMS for reuse/conversion' but is not verified against a primary source.

- Limitations
- Hobby/archive-compiled ship list, not an official record - the per-section builder attribution (all ten sections to Everett-Pacific) conflicts with DANFS's documented four-yard program and is treated as unreliable; the Portland Dock #5 reuse is a plausible but unverified lead. No buyer name, sale contract, or DRMS disposal file located. No asbestos content.

- 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 ABSD-1's sections were built (1942-43) - and that wartime demand drove unprecedented asbestos utilization in ship construction and repair.

- Limitations
- Program/era-level scholarly documentation; does not name this section or dock and does not establish that asbestos was or remains aboard this hull, nor quantity, location, condition, exposure, or causation. A floating drydock section carries markedly less asbestos-relevant plant than a propelled vessel (no boilers/propulsion).

- Finding type
- asbestos_application
- Finding
- ATSDR states: 'Until the 1970s, asbestos was widely used in the construction, shipbuilding, and automotive industries,' listing among former uses boilers and heating vessels, pipe covering, insulation products, and heat-resistant textiles, and notes these materials 'remain in many buildings, ships, and automobiles built before 1975.' A 1943-built steel drydock section falls within the documented era envelope for shipyard-installed insulation and gasket products.

- Limitations
- Industry-level public-health documentation; does not name this hull and does not establish that asbestos was or is present aboard IX-534. Era-consistent inference only - no quantity, product identity, or individual exposure is established; a drydock section's material profile (ballast pumps, compressors, generators, workshops, berthing) differs substantially from a propelled ship's.

- No qualifying ship-specific asbestos record located: no asbestos survey, material schedule, abatement contract, hazmat disclosure, or docketed asbestos case naming IX-534, ABSD-1 Section B, or the Artisan (AFDB-1) drydock sections was found in the public sources searched (see search_ledger). Authenticated CourtListener opinion search for 'IX-534' returned one name collision (Johnson v. County of Crawford, Wis. Ct. App. 1995 - statute-of-limitations case, text-level match); docket-index search returned seven unrelated civil dockets (Bates/ECF text collisions); parent-designation opinion searches 'ABSD-1' and 'AFDB-1' each returned zero results. Law-firm ship-list sites (asbestos-ships.com, freeasbestostesting.com, duboselawfirm.com) carry ABSD-1/IX-534 name entries - excluded per source policy; presence on marketing lists is not documentation.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1943 steel structure retained in Navy custody through 2007 and reportedly in commercial reuse is era-consistent with retained asbestos-containing materials, and a drydock section never attracted the survey/litigation attention propelled hulls did. Does not establish presence or absence; does not establish or defeat any exposure claim or legal eligibility.
