Mr. Molloy is a Principal Engineer and provides project management and consultation for the technical work performed by M&M Engineering. In addition to failure analysis, Mr. Molloy has intimate knowledge of many of the world’s most widely utilized combustion turbine compressor and hot section components. Having worked at a service center for a major combustion turbine supplier company, Mr. Molloy has witnessed the normal and abnormal degradation of numerous types of hot section components.
Mr. Molloy has been involved in outages at power plant utilities and has been involved in major loss events related to turbomachinery failure. Mr. Molloy has been involved in rotor life extension efforts in the US, Mexico and Canada. In addition to gas turbines, Mr. Molloy also has experience with steam turbines and reciprocating engines and their failure mechanisms.
Mr. Molloy participates in large, multi-disciplined teams conducting root cause investigations into failures for M&M Engineering and commercial clients. These programs deal with root cause failure analysis, life assessment, fitness-for-service, and repair of machinery, with emphasis on loss prevention/loss control. Mr. Molloy is involved in the failure analysis and condition assessment of a wide range of components not limited to combustion turbine units, but also including pressure vessels and piping, boilers and auxiliaries, heat exchangers and other rotating equipment. Failure analysis examinations include development of laboratory testing programs for parts received, supervision of laboratory work, interpretation of laboratory results, and issuance of written and/or oral reports.
