Abstract: A steam turbine has a single-shell turbine casing and specific inner casings arranged inside the turbine casing. The steam turbine has a turbine casing with an outer wall, a turbine shaft mounted rotatably about a turbine axis in the turbine casing, a first turbine part, and at least one second turbine part which is arranged downstream of the first turbine part in the axial direction of the turbine shaft, wherein the expansion direction for steam conducted through the steam turbine runs from the first turbine part to the second turbine part, wherein between the first turbine part and the second turbine part, a sealing shell is arranged on the turbine casing, in particular on the inner side of the outer wall for rotation therewith, the sealing shell being formed in a sealing manner with respect to the turbine shaft via sealing elements.
