ABSTRACT
The paper presents a probabilistic analysis of an evaporator of a desalination plant. Multi stage flash desalination process is being used for water purification. The desalination plant operates round the clock with seven evaporators and during normal operation; six of these evaporators will be in service while one is under maintenance and works as standby. Any major failure/annual maintenance brings the evaporator to a complete halt and stops the water production. The priority is given to repair over maintenance. For the present analysis, seven years maintenance data has been extracted from the operations and maintenance reports of the plant.Measures of the plant effectiveness have been obtained probabilistically. Semi-Markov processes and regenerative point techniques are used in the entire analysis.
