- NavSource is the standard volunteer-compiled service-craft reference, not a government record; it is the only located source for several milestones (the 1986-12-11 sale date, the 2013-10-07 Paita installation date, the naming/out-of-service/stricken 'date unknown' entries, the NDSM award). The builder, 1955 delivery, 1986 SWM sale, Knight & Carver link, and 2013 Peruvian sale are independently corroborated by the shipbuildinghistory table and the California Water Board permit record (see ev-02, ev-03). No asbestos information in the source.

The Order adds Discharge Point BW-001 (Diligence) at 32 deg 39' 33'' N on the floating drydock, prohibits discharge of anything other than San Diego Bay water from the drydock's ballast tanks, and notes the drydock is covered under the federal Vessel General Permit 'when it is underway as a vessel,' coverage transferred to the new owner. The Executive Officer Summary Report states the drydock 'was previously operated by BAE Systems San Diego Ship Repair.'

The permit record contains no asbestos, materials, or construction information; it documents discharge regulation, not hull history. Linkage of this commercial 'Diligence' to ex-AFDL-48 rests on the NavSource/Colton chain (ev-01, ev-02) plus this record's matching name, capacity class, and operator sequence.

Reporting on the subsequent wind-down documents that Marine Group Boat Works acquired Knight & Carver's National City yard lease at auction (took over 2013-04-01) but that the company's floating dry dock 'was not part of the Marine Group Boat Works deal' - consistent with the drydock's separate 2013 sale to Peruvian interests recorded by NavSource.

[6]Era construction-practice framing per Corn & Starr (WWII shipbuilding asbestos program, carried into postwar Navy practice) and GAO HRD-80-2 (see ev-uss-diligence-afdl48-07); dock function per the NPDES record (ev-03) [other_primary]

- Finding type
- asbestos_application
- Finding
- Class/era inference only: a 1955-built U.S. Navy steel floating drydock carrying ballast/pumping machinery and repair facilities is era-consistent with asbestos-containing gaskets, packing, electrical insulation, millboard, and thermal insulation in machinery and piping - the material suite standard in Navy construction of the period. The dock's repair mission (lifting Navy and commercial vessels for underwater-hull work, coating removal, and mechanical repair) additionally placed its crews around client-vessel insulation suites that commonly contained asbestos through the documented Navy asbestos era.

- Limitations
- Design/era inference, not a hull record - no construction specification, materials schedule, or survey for this dock was located. Corn & Starr documents the WWII program specifically; its use here is era-boundary context (a 1955 hull sits just past the documented period), so the inference is weaker than for a wartime build. A non-propelled floating dock has a far smaller machinery and inhabited-space footprint than a steam vessel; its asbestos loading would correspondingly be lower. Establishes nothing about quantity, condition, present-day presence, individual exposure, or causation.

- GAO product page HRD-80-2 (full text blocked, HTTP 403 - product-page description used)
- Finding type
- gov_survey
- Finding
- GAO documented the Navy's asbestos-protection program - standing policy (1975) removed asbestos insulation only when damaged or required for repairs, modified 1979 to selective replacement in high-maintenance areas - meaning original-era insulation typically remained in place aboard Navy hulls for decades unless a yard period disturbed it. A 1955-built service craft in Navy custody through 1986 falls squarely within the documented program era.

- Finding
- Litigation-posture context for the vessel type (not this hull, not asbestos): Fifth Circuit doctrine holds that 'as a matter of law, a floating dry dock is not a vessel when it is moored and in use as a dry dock' - Keller v. Dravo Corp., 441 F.2d 1239, 1244 (5th Cir. 1971), cert. denied 404 U.S. 1017 (1972), following Atkins v. Greenville Shipping Corp., 411 F.2d 279 (5th Cir. 1969) and Chahoc v. Hunt Shipyard, 431 F.2d 576 (5th Cir. 1970). Workers injured on moored floating drydocks were accordingly confined to Longshoremen's and Harbor Workers' Compensation Act remedies rather than vessel-owner negligence/unseaworthiness theories.

Relevant to how injury claims by drydock crews were channeled; the Keller court expressly declined an absolute rule that a floating drydock can never be a vessel.

One operator-level hit classified and excluded: heirs of an insulation contractor sued BAE Systems San Diego Ship Repair Inc. f/k/a Southwest Marine, Inc. alleging asbestos exposure 'at various shipyards in California, Washington and Hawaii' ~1980-mid-1990s (Freeman v. BAE Systems et al., S.D. Cal.) - an asbestos pleading naming the dock's then-operator but not the hull; excluded as non-qualifying. Name-collision hulls logged: USS Diligence (BAR-18), a WWII Lend-Lease repair ship transferred to the Royal Navy as HMS Diligence (the 'Diligence AR-18' of the PRIMARY source row - a different hull); USCGC Diligence (WMEC-616), a 210-ft cutter; and the 18th-19th century revenue cutters of the same name.
