IMPROVE THE OPERATING PERFORMANCE OF SEA WATER SYSTEM IN MED/TCD UNIT IN EGYPT USINGSIX SIGMA METHOD

Abstract

The purpose of this paper is to establish a maintenance program for the sea water System as a critical part from Desalination Unit type (MED/TCD), to satisfy all requirements needed as the main supplier for most of the systems in the desalination unit, improve the performance of desalination unit, and increase the life time of its components. The methodology/approach – by applying the scientific method (four step method) plus the PDCA cycle, it means we apply the Six Sigma philosophy. To improve the performance of the multi effects Desalination unit and increase the operational lifetime, we will work on one of the critical system in the MED/TCD unit (Sea Water System SWS) establishing maintenance program using the Six Sigma philosophy, define, measure, analyze, improve, and control (DMAIC) method for problem-solving methodology in MED/TCD Unit, to increase the Reliability and Availability of the MED/TCD Unit and increase the unit lifetime.
