Product Description

Terry Steam Turbine Company allegedly supplied small horizontal auxiliary steam turbines to the U.S. Navy — commonly used as turbine drivers for feed pumps, condensate pumps, fire and bilge pumps, forced-draft blowers, and generator sets aboard steam-plant hulls from the 1940s through the 1970s. Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that Terry auxiliary turbine casings and steam chests were lagged with amosite or chrysotile block insulation, over-wrapped with woven asbestos-fabric lagging, and pointed with asbestos finishing cement to retain casing heat and prevent burns in the machinery space.

Every casing lift for wheel inspection, nozzle repair, or bearing renewal allegedly required the block and fabric insulation to be cut and stripped, generating dry asbestos-fiber debris, and later re-installed with fresh asbestos-loaded materials. Terry drivers also carried compressed asbestos sheet gaskets at every casing flange, throttle body, and steam inlet.

Workers Exposed

  • Machinist’s mates (MM) opening Terry auxiliary turbine casings to inspect wheels, nozzles, and bearings during shipboard overhauls.
  • Boiler tenders (BT) working the feed pumps, forced-draft blowers, and fire pumps driven by Terry auxiliary turbines.
  • Shipyard machinists performing depot-level Terry turbine rebuilds at Navy and private overhaul yards.
  • Insulators removing and re-installing block and fabric lagging on Terry driver casings.
  • Pipefitters (UA) breaking steam supply lines to Terry auxiliaries and returning them to service.

Bystanders sharing the auxiliary-machinery compartment were exposed to airborne fibers released by casing-strip work and lagging debris.
