Abstract
A transportable gas turbine module including a baseplate supporting at least a gas turbine and a load drivingly connected to the gas turbine. The module further comprises a structure surrounding the gas turbine and the load and connected to the baseplate. The baseplate is designed such that it can support a heavy duty as turbine having a rated power of not less than 80 MW.
Claims25
A gas turbine module, the gas turbine module comprising:
- a baseplate supporting at least one heavy duty gas turbine having a rated power of not less than 80 MW and a load drivingly connected to the at least one heavy duty gas turbine;
- and
- a structure surrounding the at least one heavy duty gas turbine and the load and connected to the baseplate, wherein:
