Abstract: In a method of exchanging a machine part of a machine plant, the machine part to be replaced being one of multiple machine parts of the machine plant, the multiple machine parts being coupled to one another and being arranged on a common table plate which is anchored, via individual supports, in the ground, and which has recesses for accommodating the machine parts, a metal frame is set up. Bearings are provided on a new machine part, and the machine part is assembled, oriented, and tested on the metal frame. A machine part to be replaced is uncoupled from the multiple machine parts. The machine part to be replaced is removed from a recess in the table plate. Ground supports for the new machine part on the metal frame are installed and anchored to the ground in the area of the recess. The new machine part is positioned on the metal frame on the metal supports. The new machine part on the metal frame is connected to the metal supports.

Abstract: A combined installation configured as a single-shaft installation with common shafting (1) consists essentially of a gas turbine, a steam turbine, the generator (10), which is located between them, and the associated auxiliary systems (12). The generator (10) and the associated auxiliary systems (12) are arranged on a slab (8) which can be displaced transverse to the common shafting (1).

Abstract: In a method of replacing a machine part (5a, 5b) of a machine installation whose essential interconnected machine parts are arranged on a common base plate (7) which is secured in the ground by individual supports (8), a purpose-built base plate (7b) is produced in a preparatory phase, on an adjacent foundation slab (12), for the newly to be connected machine part (5b). On this base plate the machine part (5b) is provided with mountings, undergoes final assembly, is aligned and has all its functions tested. In a replacement phase, the machine part (5a) to be replaced is disconnected from the remaining machine part, its base plate section (7a) is servered from that (7) of the remaining machine part and from the individual supports (8) and it is displaced onto an auxiliary structure. The structural unit comprising the "machine part/base plate newly to be connected" (7b, 5b) is displaced by hydraulic means to take the place of the severed base plate.
