Murphy´s law

This paper deals with several identical turbine-generator sets, rated 13.8 kV, 29 MVA, for powering three separate floating offshore platforms. This article describes the generator sets testing program, the series of events leading up to the failure, a credible analysis of the failure, the steps taken to prevent future incidents, and conclusions regarding testing prior to acceptance of generator sets. A key lesson from this case is that even when electrical and mechanical equipment are being operated under the most controlled of environments, the element of risk is still present. Prior to conducting these types of tests on the vendor´s test stands, the vendor should provide documentation that routine maintenance and testing has been performed.
