Abstract: The disclosure pertains to a mounting arrangement for installing and removing a turbine component. The mounting arrangement has a base cage, a main cage, and an inner structure. The base cage includes an interface for connection to a casing of the turbine, and an interface for connection to the main cage. The main cage includes an inner structure interface for movable connection to the inner structure. The inner structure is arranged at least partly inside the main cage and the inner structure interface is configured to allow a movement of the inner structure along a defined trajectory in the main cage. The inner structure includes a first face of a component interface for holding the turbine component. The disclosure further refers to a method for mounting and removing a turbine component.

Abstract: A turbine includes an outer casing and an inner casing surrounded by said outer casing. The outer casing and inner casing are coaxially arranged with respect to a machine axis. The outer casing and inner casing are each divided in a split plane into an upper part and a lower part. The upper and lower parts are connected with each other in said split plane by means of a flanged connection. The disassembly process is improved by the flanged connection of the upper and lower part of the inner casing comprising a plurality of bolts, which extend each through through holes in respective flanges of said flanged connection of the inner casing, protrude from said through holes at both ends with a threaded section, and are tightened by means of nuts screwed on said threaded sections at both ends of said bolt.

Abstract: The method for removing an inner casing from a machine includes removing a top part of the outer casing, removing a top part of the inner casing, removing the bottom part of the inner casing, before removing the bottom part of the inner casing connecting the bottom part of the inner casing to the rotor, such that the bottom part of the inner casing is supported by the rotor, then rotating the rotor around the longitudinal axis to make the bottom part of the inner casing accessible.
