An insertion/extraction system and method for a compressor casing and a compressor bundle. The system includes a cradle extending from a first axial end of the compressor casing and configured to provide support for the compressor bundle during insertion, and an extension assembly coupled to a first axial end of the compressor bundle and extending therefrom into the compressor casing during insertion of the compressor bundle into the compressor casing, during extraction of the compressor bundle from the compressor casing, or both. The system further includes a support member that engages the extension assembly and the compressor casing to support the first axial end of the compressor bundle via the extension assembly, the support member configured to allow relative movement between the support member and the extension assembly during insertion of the compressor bundle into the compressor casing, extraction of the compressor bundle from the compressor casing, or both.

The insertion/extraction system of claim 4, wherein: the extension assembly includes a rigid tubular body coupled to the first axial end of the compressor bundle and a horizontal plate coupled to the tubular body and extending parallel thereto; andthe carrier assembly includes a roller that engages the horizontal plate of the extension assembly to allow the extension assembly to move relative to the support member at least when the cylinder is expanded. 6. The insertion/extraction system of claim 4, wherein the base assembly includes an arcuate member shaped complementarily to the inside of the compressor casing, wherein the arcuate member is configured to engage the inside of the compressor casing when the cylinder expands. 7. The insertion/extraction system of claim 6, wherein the base assembly further includes: a bracket having two sides supporting the carrier assembly and a cross-member extending between at the two sides; anda rod extending through the cross-member and configured to engage the cylinder and the arcuate member when the cylinder expands so as to transmit force between the carrier assembly and the base assembly. 8. The insertion/extraction system of claim 4, further comprising a casing extension coupled to a second axial end of the compressor casing to support the base assembly when the compressor bundle is fully inserted. 9. The insertion/extraction system of claim 1, wherein: the extension assembly includes a tubular body having a length that is at least as long as a distance between the first axial end and a second axial end of the compressor casing; andthe support member includes a support block coupled to the second axial end of the compressor casing, the support block configured to support the tubular body and to allow for relative movement between the support block and the tubular body. 10.
