For the purpose of reducing the consumption and increasing the production efficiency, the Indonesian Sinochem Palem Power Plant signed a contact with our company to carry out frequency conversion and technical reformation of two high-pressure feed pumps, low-pressure feed pumps and condensate pumps. Since the grid-approved shutdown time window is very limited, there is almost no time reserved for handling any unexpected situations. The frequency conversion and new control logic must be successfully launched in one time. Under the effective cooperation with the owner team, our engineers carefully planned each step. Ultimately the project was successfully completed within 40 hours, and put the GT generator on the grid on time. It has received great praise from the owner.
