Abstract
System for washing a gas turbine engine. The system comprises a spray device including at least one nozzle adapted to inject liquid into an inlet of said engine during a washing operation; a wash unit adapted to distribute said liquid to said spray device; and a positioning device adapted to move said spray device in three dimensions, thereby enabling a positioning of said spray device in a washing operation position in said three dimensions relative said engine inlet without any contact between the spray device and the engine. The invention further relates to a vehicle for making the inventive system mobile and to a mobile system for serving a gas turbine engine comprising a mobile vehicle carrying the washing system and a liquid collecting unit comprising a collecting device adapted to collect waste wash liquid emanating from the engine during a washing operation of the engine.
