[2]DANFS, Earl K. Olsen (DE-765) (namesake biography, builder, dates, convoy and Pacific service narrative, reserve/NRT career, second decommissioning; verbatim transcription - live NHHC page serves 404) [nhhc_danfs]

- Finding
- DANFS record for this hull: launched 13 February 1944 by Tampa Shipbuilding Co., Inc., Tampa, Fla.; sponsored by Mrs. H. E. Olsen; commissioned 10 April 1944, Lcdr. W. F. DeLong USNR in command; schoolship for the Fleet Sound School, Key West, 24 June-13 August 1944; six Atlantic convoy voyages Boston/New York-United Kingdom 28 August 1944-24 May 1945; on 13 March 1945 rescued two men and escorted collision-damaged USAT J.W. McAndrew and French carrier Bearn into Ponta Delgada, Azores; Pacific from 8 June 1945 (Pearl Harbor 19 July; Manila 3 September; four LST-escort voyages to Yokohama; Philippines operations to 9 January 1946); returned San Pedro 24 February 1946; decommissioned in reserve at Green Cove Springs 17 June 1946; Naval Reserve duty from 13 December 1946 (towed to Tampa, reduced complement); recommissioned 21 November 1950; NRT homeports Charleston (7 January 1951) and Philadelphia (18 July 1953), Caribbean/European reserve cruises summers 1951 and 1955; out of commission in reserve at Philadelphia 25 February 1958. Specifications block: 1,240 tons; 306 ft; 21 kt; complement 186; class Cannon.

- Limitations
- DANFS documents service history and specifications, not materials or asbestos content. The transcription does not state the laid-down date (carried from NavSource) and ends at the 1958 decommissioning - striking (1972) and disposal (1973) are from NavSource. Mirror transcription cited because the live NHHC page returns 404.

- NavSource timeline for this hull: keel laid 9 March 1943 by Tampa Shipbuilding Co.; launched/christened 13 February 1944; commissioned 10 April 1944 at Lee Terminal Dock, Tampa; decommissioned Green Cove Springs 17 June 1946; assigned NRT ship 13 December 1946, towed to Tampa; recommissioned Tampa 21 November 1950; reassigned NRT Charleston 7 January 1951; reassigned NRT Philadelphia 18 July 1953; decommissioned at the U.S. Naval Base, Philadelphia 25 February 1958, custody to CO Philadelphia Group, U.S. Atlantic Reserve Fleet; struck from the NVR 1 August 1972 (13 years 4 months total service); sold for scrapping to Boston Metals Co. 28 September 1973 (DRMS Sale #16-4017); scrapped 1974-75 at the Boston Metals Curtis Bay Yard, Baltimore, Md. Specifications: DET type (diesel-electric tandem motor drive, long hull); 4 GM 16-278A diesel engines with electric drive, 6,000 shp, 2 screws; complement 15 officers / 201 enlisted.

- Scrapping-yard workforce, Boston Metals Curtis Bay Yard, Baltimore, 1974-75 (shipbreaking)
- Limitations
- Secondary compilation, not a primary document - but its disposition data (NVR strike date, DRMS sale number, scrapping yard) is internally consistent and sourced to official records; Wikipedia reads 'sold 15 October 1973' vs. NavSource's DRMS sale date of 28 September 1973 - conflict carried in gaps. No asbestos or materials information.

[4]DANFS specifications block (Cannon class; diesel-electric plant; 21 kt) + NavSource specifications (4 GM 16-278A diesels, electric drive) + Atlas shipyard dataset, Tampa Bay Shipbuilding record (tier-3 asbestos-era yard) [other_primary]

- Finding type
- asbestos_application
- Finding
- Era/yard inference: a Cannon-class (DET-design) destroyer escort built 1943-44 would have carried era-standard asbestos applications appropriate to a diesel-electric ship - exhaust insulation, gaskets and packing, electrical insulation, brake linings, and deck coverings - but no boilers or steam lagging; builder Tampa Shipbuilding is documented as a tier-3 asbestos-era yard in the Atlas dataset (yard-level record, not hull documentation).

- Limitations
- Class/era and builder-yard inference only - NOT a hull-specific finding. The diesel-electric plant means the largest asbestos categories of steam ships (boiler and steam-line insulation) do not apply; does not quantify material or establish any individual's exposure aboard this hull.

- Finding type
- gov_survey
- Finding
- GAO documented the Navy's extensive shipboard asbestos insulation use, with substitution not beginning until the early 1970s - placing this hull's construction (1943-44), active service (1944-46, 1950-58), reserve-fleet custody (1946-58; Philadelphia 1958-72), and disposal (1973-75) entirely inside the documented asbestos era.

[6]CourtListener API v4 searches (authenticated, via fleet helper): exact-name "Earl K. Olsen" on opinion (type=o) and RECAP docket (type=r) indexes; hull-number "DE-765" / "DE 765" queries [court_record]

- Finding
- Exact-name searches for "Earl K. Olsen" returned zero results on both the opinion index (type=o) and the RECAP docket index (type=r) - no indexed case or docket names the vessel. Hull-number searches ("DE-765", "DE 765") were attempted repeatedly and blocked by the fleet pacing limiter for the full session; they remain an open item (search_ledger sl-uss-earl-k-olsen-de765-08).

- Limitations
- A zero search result means no indexed opinion or docket names the ship - it does not prove no suit was ever filed naming the vessel (unindexed and PACER-only filings are outside the sweep). The hull-number sweep is incomplete, not negative: 'DE-765' strings may collide with unrelated docket identifiers (the DE-766 sibling record showed that pattern), so any future hit requires manual classification before it can be treated as qualifying.

- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record located for DE-765: no hull ACM survey, abatement contract, material list, or hazmat disclosure was found, and the hull no longer exists (scrapped 1974-75 at Boston Metals, Curtis Bay, Baltimore). No asbestos case naming the vessel was located in the CourtListener indexes searched.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - era materials would have been present per class/era inference, and 1974-75 shipbreaking predates most asbestos documentation practices; disposal-era records (DRMS sale file, scrapping-contract material disclosures) are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.
