Hazard and Operability Study (HAZOP) and Risk Analysis of Boiler Section of Egbin Power Plant Lagos

Abstract

In this paper, the Hazard and Operability Analysis HAZOP) studies carried out on the boiler section of Egbin Power Plantto validate the hazard and safe operations of the plant are presented. The aim is to identify all the corrective measures to improve safety and to provide refresher training for the operating personnel as well as to look at different scenarios that may come up as production is going on. The methodology used in carrying out the Hazard and Operability Studies was by using a well-structured and systematic method such as the combination of relevant keywords and parameters/variables like flow, temperature, pressure, level, etc. which resulted in deviations. These deviations were caused byequipment malfunctions, operational problems, and other factor. These resulted in consequences thatlead to low power output. The consequences of any action are the risks that should be avoided for the plant to continue to run. To overcome these problems, a tentativeactionwas provided which would make the operator take immediate action to mitigate the problems while maintenance would be carried out to avoid plant shutdown.
