ABSTRACT:
A system and method for easily separating upper and lower turbine shells involves forming elongated access pockets vertically aligned across the upper and lower turbine shells and at multiple locations on the turbine shells. Telescoping hydraulic rams are placed into elongated access pockets at each of the multiple locations for lifting the upper shell off of the lower shell. The telescoping hydraulic rams are connected to a controller for controlling each of the rams to operate in parallel with the other rams. Once the turbine shells are separated the upper turbine shell can be removed by conventional block and rigging.
