3.1 Employer’s design Drakensberg pumped storage scheme consists of four 250 MW Pump-turbine units. Each unit has a Main Inlet Valve (MIV). The main function of the MIV is to isolate the Pump-turbine from the penstock. Each MIV is equipped with bypass line and a hydraulically operated bypass valve. The bypass line is connecting the MIV body with the Pump turbine spiral case extension. The function of the Main Inlet Bypass Valve and Bypass Line is to achieve balance pressure between the upstream and downstream sides of the MIV, prior to the Main Inlet Valve opening. The four MIV’s are located in an underground cavern. Overhead cranes are available to assist with maintenance of the MIV’s. Each of these MIV’s are installed in an open concrete pit, and personnel access is gained by a series of cat-ladders. Due to repeated failures of the existing bypass valves, excessive cavitation damage and the high vibration experienced in the existing bypass line, the replacement of the complete bypass line and valve with a re- designed bypass line configuration and a more modern design hydraulically operated Bypass Valve to be applied. The diameter of the Bypass Line and Bypass Valve to be increased with the new design, and the location of the bypass valve to be such that it shall be fitted directly to the pump-turbine spiral case extension pipe.
