Marinship Corporation

Facility Overview

Marinship Corporation was built from scratch in early 1942 on a former Northwestern Pacific Railroad repair yard at Richardson's Bay in Marin County — just three miles north of the Golden Gate Bridge. W.A. Bechtel Company, the yard's parent, used wartime condemnation authority to acquire additional land, relocating 42 homes from Pine Point within two weeks. Approximately 26,000 pilings were driven into bay mud to support the shipways and fabrication shops; a 300-foot-wide, 1.5-mile-long deepwater channel was dredged in Richardson Bay to allow newly launched vessels to reach San Francisco Bay.

The first keel — Liberty ship William A. Richardson — was laid on June 27, 1942, just three months after construction of the shipyard began. After launching 15 Liberty ships, Marinship retooled to produce the larger T2-SE-A2 tankers. On June 16, 1945, Marinship set a world record by constructing and delivering the tanker SS Huntington Hills in 33 days (28 days on the ways, 5 days fitting out). The yard closed in May 1946 as wartime contracts were cancelled.

Marinship is also historically significant as the site of James v. Marinship Corp., 25 Cal.2d 721 (Cal. Sup. Ct. 1944), a landmark civil rights case in which the California Supreme Court — with future U.S. Supreme Court Justice Thurgood Marshall arguing for the plaintiffs — held that unions could not exclude African American workers from membership. The ruling was extended to all unions and workers in California by the U.S. Supreme Court in 1945.

1942–1944 USMC Industrial Hygiene Survey Series

The U.S. Maritime Commission (USMC) conducted a series of industrial hygiene surveys at Pacific Coast shipyards during 1942–1944 as part of its wartime occupational health program. Marinship Corporation was among the yards surveyed. The surveys documented asbestos dust exposure among insulators and pipefitters during Liberty Ship and T2 tanker construction, recording dust counts during cutting and fitting of amosite pipe covering and boiler block insulation in confined engine rooms and boiler spaces.

The survey series is the primary occupational health record for Marinship workers. Because Marinship closed in 1946 — more than two decades before NIOSH's Health Hazard Evaluation (HHE) program began in 1970 — no NIOSH cohort study was ever conducted for this yard. The USMC surveys represent the only contemporaneous government documentation of asbestos exposure conditions at Marinship.

W.A. Simons Asbestos Trust — California Site List (2020)

The W.A. Simons Asbestos Trust's California Site List (September 2020) independently confirms Marinship as a high-exposure site, listing MARINSHIP–SAUSALITO, CA with an exposure window of January 1, 1940 – December 31, 1969. The Simons Trust site list is a claims-administration document that reflects the trust's determination, based on its own evidence review, that workers at listed sites were exposed to asbestos-containing products for which the trust is liable.

The exposure window extends to December 31, 1969 — more than two decades after Marinship's 1946 closure — indicating that the trust recognizes exposure from post-war repair and maintenance work at the Sausalito site, not only from wartime shipbuilding. This is consistent with the documented pattern at other Bay Area shipyards where asbestos-containing materials installed during WWII construction remained in place and were disturbed during subsequent repair operations.

EPA CERCLA Environmental Record

The Marinship site in Sausalito has been the subject of EPA CERCLA environmental review. Asbestos-containing materials were documented in soil and debris at the former shipyard site, consistent with the wartime use of asbestos insulation products throughout the facility. The site's remediation was conducted under CERCLA authority.

Asbestos Products Documented at Marinship

The USMC survey series and corroborating records document the following asbestos-containing products at Marinship. All WWII-era Pacific Coast shipyards used the same Maritime Commission-specified product set; Marinship-specific product naming in the survey series has not been separately published.

"Verified" = named in a primary government survey document or trust site list. "Probable" = consistent with documented product use at comparable WWII Pacific Coast yards; not yet named in a Marinship-specific retrieved document.

Historical Context: James v. Marinship Corp., 25 Cal.2d 721 (1944)

Marinship is historically significant beyond its asbestos exposure record. In 1944, the California Supreme Court decided James v. Marinship Corp., a landmark civil rights case in which future U.S. Supreme Court Justice Thurgood Marshall successfully argued that the International Brotherhood of Boilermakers could not exclude African American workers from full union membership through a discriminatory auxiliary system. The court held that a union with a closed-shop contract could not maintain racially discriminatory membership practices.

The ruling is relevant to asbestos litigation context because it establishes the occupational trades present at Marinship — boilermakers, pipefitters, insulators — and the scale of the workforce. At its peak, Marinship employed 20,000 workers, including a significant African American workforce drawn from across the United States by wartime wages. The post-war displacement of Black workers — from 20,000 in July 1945 to near zero by the yard's closing — is documented in the historical record and is relevant to understanding the population of workers who may have carried asbestos-related disease into communities that were subsequently denied access to adequate healthcare.

Pacific Coast Cluster: Marinship vs. Long Beach Naval Shipyard

Marinship and the Long Beach Naval Shipyard represent two distinct evidence profiles within the Pacific Coast cluster — a wartime commercial yard with government survey evidence, and a naval repair yard with a peer-reviewed NIOSH cohort study.
