Many customers are operating turbines for very long periods of time making the turbine inefficient. There are also cases where in the quest for growth, parameters have changed, making the turbine inefficient. These are cases where we engage with customers, understand the requirement, review and present offers to improve efficiency of the turbines, resulting in significant savings. We use our latest generation blades for the rotor and matching diaphragms to ensure enhanced performance. We also exercise the option of going impulse, reaction or hybrid. The intent is to protect the casings and only replace internals with our design steam path to achieve the efficiency improvement and these are extremely significant. This also ensures that the footprint remains the same and hence there is no need for any review of the civil foundations.
