Shipbuilding is one of the occupations most closely linked to asbestos disease. The National Cancer Institute lists shipbuilding trades among occupations in which asbestos-related health hazards have been recognized (NCI asbestos fact sheet). A ship concentrated everything dangerous about the material. Asbestos insulation covered boilers, steam lines, and bulkheads, and it was installed and torn out in compartments with almost no ventilation. The same NCI source identifies asbestos exposure as the primary cause of mesothelioma, a cancer that often appears decades after the exposure that caused it.
Why Shipyard Asbestos Exposure Was Worse Than Construction Sites
A building has open rooms and windows. A ship has sealed steel compartments connected by hatches. When insulators covered a warship’s steam lines, or a repair crew stripped old insulation during an overhaul, the dust stayed in the engine room, fire room, and passageways alongside the workers. Below decks, every trade breathed what every other trade produced. Riggers, laborers, machinists, painters, and electricians who never handled insulation still worked in its dust for years. Makeshift lighting and ventilation, along with wartime production pressure, made conditions worse. During the busiest years, yards ran around the clock and sent new workers below decks with little training.
Delaware River Shipyards: Philadelphia Naval Shipyard and Sun Ship Asbestos History
The Delaware River was one of the nation’s major shipbuilding corridors, and two of its largest yards anchor Pennsylvania’s asbestos history:
The Philadelphia Naval Shipyard built and overhauled Navy vessels for much of the twentieth century. Overhaul work is especially significant. Modernizing an older warship often meant removing its original asbestos insulation one compartment at a time.
Sun Shipbuilding in Chester ranked among the largest private shipyards in the world during the World War II era and employed tens of thousands of Delaware County workers at its peak.
Smaller yards and marine repair operations along the river add to the list. Generations of families in South Philadelphia, Chester, and the surrounding river towns worked these yards, often father and son. The pattern of repair work matters legally, too, because overhaul records can link specific ships and their insulation systems to specific piers and time periods.
Shipyard Jobs With High Asbestos Exposure Risk
Nearly every shipyard job carried some exposure. Insulators and pipe coverers had the most direct contact. Boilermakers, pipefitters, machinists, and welders worked in the same compartments, and their exposure patterns are covered on our pages for boilermakers and welders. Even shipfitters and topside laborers encountered asbestos in cement, gaskets, and the yard’s general dust. The complete list of trades is on our occupations with asbestos exposure index.
Secondhand Asbestos Exposure in Shipyard Families
Yard workers carried dust home on their clothes, and the National Cancer Institute notes the risk to family members from fibers brought home this way (NCI). In shipyard neighborhoods, take-home exposure comes up repeatedly. The person diagnosed today is sometimes the worker’s widow or child rather than the worker. Some Chester and South Philadelphia households have more than one exposure history under the same roof: the yard worker, the spouse who washed the work clothes, and a son who followed his father into the yard.
Mesothelioma Compensation for Pennsylvania Shipyard Workers and Families
Shipyard cases draw on extensive records, including yard employment files, Navy and maritime documentation, and decades of litigation that identify the insulation products used aboard specific ship classes. Compensation may come from product manufacturers through lawsuits and from asbestos bankruptcy trusts, which the U.S. Government Accountability Office reported held billions of dollars in assets (GAO-11-819). Navy veterans exposed aboard a ship may also qualify for VA benefits, and former civilian employees of the naval shipyard may have additional options.
Pennsylvania sets strict deadlines for asbestos claims, and different deadlines can apply to living patients and to families who have lost a loved one. Because these time limits can be short, it is important to speak with an attorney soon after a diagnosis or death. The same records that make these cases provable also make them concrete: hull numbers, dry dock logs, and testimony from former shipmates.
