A system and a method are for reducing a corrosive environment for a pipeline segment defined between a first end and a second end. The pipeline segment has a fluid pipe, a protective cover surrounding the fluid pipe and an annular space defined between the fluid pipe and the protective cover, the annular space being at least partly filled with an insulation material. The method has the steps of: providing an inlet at the first end for supplying a protective gas inside the annular space; providing a sensor at the second end of the pipeline segment; arranging a sensing element of the sensor inside the annular space for monitoring any corrosive environment therein; providing a protective gas source in fluid communication with the inlet; and controlling the supply of protective gas from the protective gas source based on signals from the sensor.
