Accordingly, there is provided an improved flexible lubricity additive dosing system adaptable to a gas turbine operating on naphtha fuel, comprising an unloading device having a portable motor driven barrel pump for transferring lubricity additive from a barrel to a storage tank, the storage tank being operably connected to the unloading device via a discharge hose, the barrel pump is connected to the portable motor drive via a flexible power cable, the storage tank provided with instrumentations for auto-change - over of gas Turbine to alternate fuel, in response to alarming signals generated by the instruments provided in the storage tank based tin the available levels or the lubricity additives in the tank. Atleast two motor driven dosing pumps are provided for metering and dosing a predetermined quantity of lubricity additives into a fuel supply device of the gas turbine. A pulsation dampener is arranged for smoothening the additive flow into the system. A flow meter is disposed to measure the follow rate of lubricity additive to the gas turbine and providing a flow signal to a dosing control device. A control device is operably connected for calculating the dosing rate based on instaneous naphtha flow rate into the gas turbine, the device transmitting corrective signals representative of the flow-rate once the flow rate measured by the flow-meter mismatches the calculated dosing rate.
