    W.D. Wash. 2:19-cv-00793-RSL, Document 552 (filed 05/17/21), pp. 1, 5-6 - ship list, Fulton Sylphon equipment recitals, causation analysis
    Finding type
    litigation_documented
    Finding
    Docketed federal asbestos action naming this hull: the estate of engineman John Dale Wineland alleged asbestos exposure from defendant products while he worked engine rooms aboard USS Dynamic (1963-66), USS PLEDGE (1966-67), USS Loyalty (1970-72), USS Tuscaloosa (1972-74), and USS Esteem (1978-80); he developed mesothelioma and died in 2018. The order recites record evidence that 'Fulton Sylphon 1.5-inch temperature regulators and temperature regulating valves were installed on the PLEDGE during or before 1955' (Dkt. #396-6 at 38, 62), that 'the Fulton Sylphon valves the Navy tested and approved for use on its vessels contained asbestos gaskets and packing' (Dkt. #396-14 at 2-3), and that the repair practices described 'would invariably create asbestos dust.' The court recited 'ample evidence to support a finding that Mr. Wineland was exposed to significant levels of asbestos dust while working in the engine rooms of the ESTEEM, the PLEDGE, and the TUSCALOOSA.'

    Limitations
    Summary-judgment-stage record, not an adjudicated finding: the court GRANTED Robertshaw Controls' motion because plaintiffs produced no evidence that its products were installed in the engine rooms where Wineland worked - the asbestos-to-product attribution failed ('the jury would have to speculate'). A defense summary-judgment win is a merits-level negative for these plaintiffs, not exposure evidence. Equipment presence is the court's recital of plaintiffs' exhibits (ship records), not a finding of asbestos content aboard; 'significant asbestos dust' is the plaintiff-favorable evidentiary recital under the SJ standard. Does not establish that any individual was exposed aboard this hull, the quantity of any material, or legal eligibility.

    W.D. Wash. 2:19-cv-00793-RSL, Document 555 (filed 07/19/21), pp. 1, 4-6 - equipment recitals and PLEDGE-specific concession
    Finding type
    litigation_documented
    Finding
    Companion summary-judgment order in the same action reciting record evidence of defendant equipment aboard this hull: 'Alfa Laval purifiers were installed in the aft engine rooms of the DYNAMIC, LOYALTY, ESTEEM, PLEDGE, and TUSCALOOSA' (Dkt. #394-2 at 15; #394-6 at 46; #394-7 at 17; #394-8 at 67) and 'DeLaval lube oil pumps serviced the main propulsion reduction gears installed on DYNAMIC, LOYALTY, ESTEEM, and PLEDGE' (Dkt. #394-2 at 15). For PLEDGE specifically the order records a plaintiff concession: 'Plaintiffs do not dispute Alfa Laval's contention that Mr. Wineland was not exposed to its products during his service on the PLEDGE' - his service records placed him in the forward engine room while the purifier sat aft, and plaintiffs' expert 'could not say that Mr. Wineland was exposed to asbestos from an Alfa Laval product while on that vessel.' Summary judgment granted to Alfa Laval on causation under maritime law (McIndoe substantial-factor standard).

Does not establish that the purifier or pumps aboard contained asbestos, that any exposure occurred, or any quantity of material. Purifier cleaning tasks were described in the record as producing no asbestos exposure per defendant's uncontested industrial-hygiene opinion.

    Official Navy fact file documents the MSO-422 (Aggressive) class design to which this hull belongs (Pledge appears in the class ship table as MSO-492): ocean minesweepers conceived in response to Korean War mining, capable of sweeping moored and bottom contact, magnetic, and acoustic mines with AN/SQQ-14 mine-countermeasures sonar; builders include J.M. Martinac Shipbuilding Corporation; power plant 4 aluminum-block diesel engines, 2 shafts, 2,400 bhp; complement 77 active (7 officers, 70 enlisted). Documents a diesel propulsion plant for this class - no boilers and no steam distribution system. The fact file records the class disposal pattern: 'some to be disposed of by the Security Assistance Program (SAP) for cash sale and others to be sold by the Defense Reutilization and Marketing Service (DRMS) for scrapping' - this hull went the SAP route.

The appellate record for the same prosecution describes DRMS bid invitations for decommissioned minesweepers Illusive (MSO-448), Inflict (MSO-456), and Fearless (MSO-442) as identifying asbestos-containing compartments marked by the Navy before sale.

Pledge was exported to Taiwan via Security Assistance Program sale rather than scrapped through DRMS, so the DRMS-flagging pathway does not map to her disposal.

    Era-typical asbestos applications aboard a 1950s diesel-propelled ocean minesweeper, inferred rather than proven for this hull beyond the litigation record: diesel exhaust-system and muffler lagging on the four main engines; machinery gaskets and packing (the Wineland record describes routine removal and replacement of gaskets and stem/shaft packing on valves, pumps, and engines by enginemen aboard sister MSOs of this class); electrical-cable insulation; deck coverings and cements; brake linings on winches, windlass, and minesweeping gear. Because the documented plant is diesel with no boilers or steam distribution, the boiler-room and steam-line insulation envelope emphasized for steam combatants does not apply - the residual envelope concentrates in engine exhaust and machinery spaces.

The first USS Pledge was a distinct WWII Admirable-class steel-hulled minesweeper - laid down 1 July 1943 by Gulf Shipbuilding Corp., Chickasaw, Alabama; launched 23 December 1943; commissioned 29 July 1944, Lt. Thomas Knotts in command; struck a mine and sank off Wonsan, Korea, 12 October 1950 after USS Pirate (AM-275) was mined alongside; one WWII battle star and a Presidential Unit Citation for Korean service. WWII-era metadata attached to this vessel belongs to AM-277; canonical operational designation for this hull is MSO-492.

    Study period
    1943-1950 (AM-277) vs 1954-2021 (MSO-492) hull timelines
    Limitations
    The DANFS 'Pledge II' header on the official NHHC page establishes the two-hull distinction; AM-277 particulars rest on the DANFS transcription at the hazegray mirror (Wayback capture) - sufficient for disambiguation, not relied on for exposure findings. Marketing listicles conflate the two hulls in single tables (mesothelioma.com lists both AM-277 and AM-492 rows) - excluded as sources.

    Finding
    No qualifying hull-survey-type asbestos record located for USS Pledge (AM-492/MSO-492) or her ROC identity Yung Teh (MSO-1309): no asbestos survey, abatement contract, material specification, hazmat disclosure, or pre-transfer environmental report naming the vessel was found in the sources searched (see search_ledger). The CourtListener API sweep could not be executed - authenticated API returned HTTP 429 (shared 2,800/day quota exhausted, ~5.9 h to reset) - so docket-level litigation screening is open-web-level, not exhaustive; the Wineland record was located by that screening, and no other case caption, docket, or opinion naming the vessel was found. The indexed VA BVA decisions check returned no result naming the hull.

    Limitations
    Absence of a located public record does not prove absence of asbestos aboard - the ship was built and served entirely inside the Navy's asbestos era, and sister-hull disposal records (ev-09) show the class carried documented asbestos at disposal; the Wineland orders document asbestos-litigation claims and equipment evidence touching this hull without adjudicated exposure. Equally, era inference does not establish ship-specific presence. Does not establish that asbestos is or was aboard this hull beyond the litigation record's contents, and does not establish or defeat any claim of exposure or legal eligibility. Litigation screening incomplete due to CourtListener quota block.
