  • Casing / Shell Analysis & Renovation

    Many casing and shell renovation methods are largely cosmetic and require continual rework which reduces reliability and lengthens subsequent outage schedules. Turbine Consultants® also co-developed a software package at EPRI's request for use by their member utilities. This program, called Turbine Casing Advisor, allows users to evaluate minor casing cracking and distortion problems on their own. TCI can perform this analysis at client request. We offer a full array of engineering and repair services which determine the root cause of casing/shell failure.
