The method involves impinging angle of attack of multiple turbo-compressor stages with droplet-loaded fluid i.e. water-loaded air, such that front stages are more heavily loaded in relation to dry operation. A staggering is carried out before or during operation by adjustable guidance series. The staggering is carried out in relation to a dry compressor in an unmodified manner during completion of the operation of underwater loading. A liquid phase of the fluid to be consolidated is utilized as injected liquid fluid. Offenbart sind Verfahren zum Betreiben eines Verdichters, wobei die Anströmwinkel einer bzw. mehrerer Turboverdichterstufen, die mit einem tropfenbeladenen Fluid, beispielsweise wasserbeladener Luft, beaufschlagt werden, derart geändert, insbesondere vergrößert, werden, dass gegenüber dem trockenen Betrieb die vorderen Stufen stärker belastet werden, ein Verdichter sowie eine Strömungsmaschine.
