Zusammenfassung:	Various embodiments include apparatuses and systems for controlling compressor clearances. In one case, an apparatus includes: a material layer sized to fit a case of a gas turbine (GT) compressor in a GT system, the material layer including a heating element for applying heat to the case of the GT compressor; and a control system coupled with the material layer, the control system configured to: determine whether a shutdown sequence is occurring in the GT system; and actuate the heating element to apply heat to the case of the GT compressor in response to determining that the shutdown sequence is occurring.
