Emerging Failures in Gas Turbine Engines Operating in Hot Environments
Abstract
Two (2) gas turbine engines operating offshore experienced Domestic Object Damage (DOD) failure with damaged blades in the HP compressor section.
The failures were caused by repeated use of a component undergoing wear accelerated by hot ambient environment (tropical climate) and operating in full load. A variety of different failure modes and how the root cause was determined is presented.
The current solution to prevent failures is to replace the component during engine overhaul. The component is the shroud box which holds the 7th Stage Outlet Guide Vane (OGV) of the engine’s IP compressor section.
Risk exposure for the remaining fleet was analyzed to prevent repeat failure and improvements were made on the online algorithm to provide earlier indication of a potential failure
