Product Description
Cooper-Bessemer (later Cooper Industries / Cooper Energy Services / Cameron) allegedly supplied large integral-engine natural-gas compressors — the “Cooper GMV” and related models — that dominated U.S. interstate natural-gas pipeline compressor stations from the 1940s through the 1990s. Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that each Cooper-Bessemer integral unit combined a large slow-speed gas engine driving reciprocating compressor cylinders on a common frame, and that both the engine side and the compressor side of the machine carried asbestos-containing insulation and sealing products.
On the engine side, plaintiffs alleged the power-cylinder heads, exhaust manifolds, turbochargers, and heat-exchanger shells were lagged with woven asbestos-fabric jackets, asbestos-cloth blanket insulation, and asbestos exhaust-wrap. On the compressor side, plaintiffs alleged the piston-rod stuffing boxes were packed with braided asbestos rope, and cylinder heads, valve covers, and unloader housings were sealed with compressed asbestos sheet gaskets. Every scheduled top-end job or valve-and-packing round allegedly required the fabric lagging to be cut open, the gaskets scraped from mating surfaces, and the packing rings driven out of the stuffing box — releasing dry asbestos fibers throughout the engine room.
Workers Exposed
- Compressor mechanics performing top-end jobs, valve-and-packing changes, and turbocharger service on Cooper-Bessemer integral units.
- Insulators (HFIAW) installing and stripping asbestos-fabric jacket lagging on power-cylinder heads and exhaust manifolds.
- Pipefitters (UA) breaking fuel-gas, suction, and discharge piping into Cooper-Bessemer frames.
- Millwrights rigging cylinders, pistons, and manifolds during major overhauls.
- Instrument fitters working pulsation-bottle, gauge, and control tubing during outages.
Bystanders in the compressor-station engine room were exposed to airborne fibers released by lagging removal, packing pull, and gasket scraping.
