Abstract
A gas turbine system is described, comprising a gas turbine, at least a first load and a second load powered by the gas turbine. The gas turbine comprises: a gas generator; a low pressure turbine; a power shaft powered by the low pressure turbine. The power shaft has a first shaft end drivingly connected to the first load and a second shaft end drivingly connected to the second load. The first load and the second load are arranged at opposite sides of the gas turbine and the power shaft axially extends through the gas turbine from a first end to a second end thereof.

A gas turbine system, comprising:
- a gas turbine, wherein at least a first load and a second load are powered by the gas turbine, and the gas turbine comprises:
- a gas generator;
- a low pressure turbine;
- and
- a power shaft powered by the low pressure turbine, the power shaft comprising a first shaft end drivingly connected to the first load and a second shaft end drivingly connected to the second load, the first load and the second load being arranged at opposite sides of the gas turbine, and the power shaft axially extending through the gas turbine from a first end to a second end thereof.
A method of operating a gas turbine system comprising a load, the method comprising:
- providing a gas generator, a low pressure turbine, and a power shaft comprising a first shaft end and a second shaft end accessible at a first end and at a second end of the gas turbine system, respectively;
- drivingly connecting a first load to the first shaft end, and a second load to the second shaft end;
- generating mechanical power by low pressure turbine;
- using a first part of the mechanical power through a first load coupling to drive the first load, and a second part of the mechanical power through a second load coupling to drive the second load.
