Foster Wheeler Marine Boilers

Product Description

Foster Wheeler Corporation was one of the most prominent manufacturers of industrial and marine boilers in the United States throughout the twentieth century. The company supplied boilers to the United States Navy and to commercial shipping operators across several decades, with production spanning the mid-1900s through periods of significant industrial and maritime expansion. Foster Wheeler boilers were installed aboard destroyers, aircraft carriers, submarines, cargo vessels, tankers, and a wide range of other military and commercial watercraft.

These boilers served as the primary power source for steam-driven vessels, generating the high-pressure steam necessary to drive turbines, power propulsion systems, and supply shipboard utilities. Because of the extreme temperatures and pressures involved in marine boiler operation, thermal insulation was a fundamental engineering requirement throughout the design and construction of these units. Foster Wheeler’s marine boilers were accordingly specified with materials intended to withstand sustained heat, and asbestos-containing components were incorporated extensively into boiler systems during this era.

Foster Wheeler marine boilers were considered industry-standard equipment for much of the twentieth century. Their presence across both naval and commercial fleets meant that an exceptionally large population of workers—shipbuilders, sailors, engineers, and tradespeople—came into contact with these units during construction, installation, operation, maintenance, and repair.


Asbestos Content

Asbestos was incorporated into Foster Wheeler marine boilers through multiple components and associated materials. Insulation applied to the exterior surfaces of boiler shells and steam piping was commonly composed of asbestos-containing blankets, block insulation, and lagging materials. Gaskets used throughout boiler systems—including at flanges, valve connections, and inspection ports—were frequently manufactured from compressed asbestos fiber. Rope packing used to seal doors, access hatches, and expansion joints also commonly contained asbestos.

Refractory and furnace lining materials inside fireboxes and combustion chambers were another documented source of asbestos exposure. These internal linings were engineered to withstand direct flame and extreme thermal cycling, and asbestos was a preferred binding or reinforcing component in many such refractory products during the mid-twentieth century.

Because boiler systems required regular inspection and maintenance throughout a vessel’s service life, workers returned repeatedly to these asbestos-laden components. Each maintenance cycle—whether replacing gaskets, repairing insulation, or relining furnace chambers—presented renewed opportunity for fiber disturbance and inhalation.


How Workers Were Exposed

Workers encountered asbestos from Foster Wheeler marine boilers across multiple occupational settings and trade categories. Exposure occurred at shipyards during initial vessel construction, aboard ships during active service, and at dry-dock facilities during overhaul and repair work.

Shipyard and construction workers who fabricated, installed, and fitted out boiler rooms were among those with the heaviest documented exposures. Applying asbestos insulation to boiler shells and steam lines, cutting gasket material to fit, and installing refractory linings all generated respirable asbestos dust in confined spaces below deck. Ship compartments and engine rooms provided little ventilation, allowing airborne fibers to accumulate to significant concentrations.

Boilermakers and pipefitters working on installed systems performed tasks that regularly disturbed existing asbestos insulation. Removing and replacing lagging to access boiler components, cutting out old gaskets, and applying new packing materials released asbestos fibers directly at the work site.

Machinists and marine engineers who operated and maintained boilers over the course of a vessel’s service life were exposed during routine inspections and repairs. Opening inspection hatches, examining furnace interiors, and servicing valves and fittings brought workers into repeated contact with asbestos-containing materials in various states of degradation.

Navy personnel—including enlisted sailors and officers assigned to engineering divisions aboard naval vessels—lived and worked in close proximity to boiler rooms for extended periods. Aging and deteriorating asbestos insulation aboard older vessels could shed fibers continuously into the shipboard environment, creating ambient exposure for all personnel in affected spaces.

Industrial workers employed at shore-based power plants, industrial facilities, and refineries that used Foster Wheeler boilers of similar design also faced comparable exposure conditions, particularly during installation, maintenance, and decommissioning activities.

Asbestos-related diseases typically have latency periods of ten to fifty years between initial exposure and clinical diagnosis. As a result, individuals exposed to Foster Wheeler marine boilers during the mid-to-late twentieth century have continued to receive diagnoses of mesothelioma, asbestosis, lung cancer, and related diseases in recent decades.


Litigation Background

Foster Wheeler has been the subject of extensive asbestos litigation in federal and state courts across the United States. Litigation records document claims filed by former Navy personnel, shipyard workers, merchant mariners, and industrial tradespeople who alleged occupational exposure to asbestos-containing components associated with Foster Wheeler marine boilers.

Plaintiffs alleged that Foster Wheeler knew or should have known of the hazards associated with asbestos in its products and failed to provide adequate warnings to workers and end users. Litigation records further document claims that asbestos insulation, gaskets, and related materials specified for or incorporated into Foster Wheeler boiler systems caused plaintiffs to develop mesothelioma and other asbestos-related diseases.

Foster Wheeler was ultimately acquired by Amec Foster Wheeler and subsequently absorbed into Wood Group. The company’s asbestos liability history has been a persistent subject in mass tort proceedings, and litigation against successor entities has continued in various jurisdictions.

Because Foster Wheeler’s asbestos liability has been addressed through ongoing civil litigation rather than through an established bankruptcy trust fund, individuals seeking compensation for asbestos-related disease associated with Foster Wheeler marine boilers typically pursue claims through direct litigation against responsible corporate entities or their successors.

Affected individuals and their families should be aware of the following:

  • Mesothelioma, lung cancer, and asbestosis caused by asbestos exposure are recognized bases for civil claims in all U.S. jurisdictions.
  • Statutes of limitations apply and vary by state; claims must generally be filed within a defined period following diagnosis or discovery of the disease’s occupational cause.
  • Navy veterans and merchant mariners may have access to VA benefits and disability compensation in addition to civil remedies, depending on service history and diagnosis.
  • Multiple defendants are common in asbestos litigation; claims may be filed against boiler manufacturers, insulation suppliers, gasket manufacturers, and vessel owners simultaneously.

Individuals diagnosed with an asbestos-related disease who have a documented history of working with or around Foster Wheeler marine boilers are encouraged to consult with an attorney experienced in asbestos litigation to evaluate available legal options before applicable filing deadlines expire.
