    Finding
    Affirmed jury verdict: Peter Juliano, a Sun Shipbuilding chipper/tank tester 1965-1973, was awarded $200,000 for asbestos-caused pulmonary and emotional injuries; Fibreboard Corp. was one of twelve manufacturers found responsible. Welder Owen McPherson (Sun Ship 1943-1976) testified he had worked on at least two of the same ships as Juliano - the Glomar Explorer and the Manhattan - and recalled PABCO and Owens-Corning products 'with asbestos noted on the packaging' in use throughout the yard, used primarily for pipe insulation in the engine and boiler rooms of ships, the areas where Juliano most frequently labored; Juliano recalled using paste-form Kaylo. The Superior Court held the product-identification evidence sufficient and affirmed.

    Sun Shipbuilding construction trades - chipper/tank tester plaintiff and welder witness, 1965-1973 window covering this hull's construction
    Limitations
    Affirmed judgment (most final stage reached) - but the exposure finding is workplace-level across hulls at Sun Ship, not isolated to this vessel: the opinion names the Glomar Explorer as one of at least two ships both plaintiff and witness worked on, and does not establish that asbestos was installed aboard this hull specifically, nor quantity. Documents construction-period (1971-73 build window) exposure at the builder yard, not in-service conditions. The opinion's 'engine and boiler rooms' phrasing describes shipboard work areas generically - this diesel-electric hull had no propulsion boilers.

    Finding
    Official CIA account: the Hughes Glomar Explorer was built under cover as Howard Hughes's commercial deep-sea mining vessel to recover the Soviet Golf II-class submarine K-129 (lost March 1968, located ~1,800 miles northwest of Hawaii at 16,500 ft). Construction ran about four years; the ship incorporated a derrick, pipe-transfer crane, docking legs, capture vehicle, and a center docking well ('moon pool'). She sailed from Long Beach, arrived over the site 1974-07-04, and conducted salvage for more than two months under Soviet surveillance; the submarine section broke apart during the lift and only a portion was recovered - including the bodies of six Soviet submariners, buried at sea with military honors. Press disclosures beginning with the Los Angeles Times 1975-02-07 blew the cover; further recovery was cancelled.

The ALJ vacated the contested citations; the Commission affirmed (Citation 2 affirmed by an equally divided Commission, so without precedential weight as to that item).

    Finding
    Non-asbestos litigation naming the vessel: the FOIA 'Glomar response' lineage. Phillippi v. CIA upheld the Agency's neither-confirm-nor-deny response to a request for records on CIA contacts with media about the Glomar Explorer project; the follow-on 1981 Phillippi opinion and Military Audit Project v. Casey continued the records-disclosure fight over Project AZORIAN. The ship's name became the doctrinal label for the refusal to confirm or deny the existence of records.

Completed 1998; first well for Chevron in ~7,800 ft of water (Mississippi Canyon), a world record; Transocean decided to scrap the vessel in April 2015.

    The hull's 1971-73 construction window immediately precedes and straddles the first federal asbestos bans: EPA promulgated the Asbestos NESHAP on April 6, 1973 (banning spray-applied asbestos fireproofing/insulation) and in 1975 banned installation of friable pre-formed and wet-applied asbestos pipe insulation and block insulation on facility components. Asbestos products remained lawful and in documented use at the builder yard throughout this hull's construction (see ev-01).

The only docketed asbestos record naming this hull is the construction-period Juliano verdict (ev-01). The 2015 scrapping at Zhoushan predated enforceable Hong Kong Convention IHM requirements, so no hazardous-materials inventory for this hull is expected in the public record.
