Modular gas turbine system

1. A modular gas turbine system, comprising:

a base plate;

mounted on the base plate, a gas turbine engine having a rotation axis, a first air compressor section and a second air compressor section;

at least one rotating load, mechanically coupled to the gas turbine engine and mounted on the base plate;

a supporting frame extending above the base plate;

an air intercooler fluidly coupled to the first air compressor section and second air compressor section, the air intercooler configured and arranged to cool partly compressed air from the first air compressor section in heat exchange relationship with a heat removal fluid;

wherein a plurality of secondary coolers are arranged on the supporting frame above the base plate at a level above at least one of the gas turbine engine and the load, and are in fluid exchange relationship with the intercooler, the heat removal fluid being in heat exchange relationship with a cooling medium in the secondary coolers.

2. The modular gas turbine system of claim 1 , wherein the secondary coolers are air coolers and the heat removal fluid is in heat exchange relationship with cooled ambient air in said secondary coolers.

3. The modular gas turbine system of claim 1 , further comprising at least one lube oil cooler arranged on the supporting frame.

4. The modular gas turbine system of claim 3 , wherein the at least one lube oil cooler is arranged at the same level as the secondary coolers.

5. The modular gas turbine system of claim 1 , further comprising a first bridge crane movably supported on the supporting frame.

6. The modular gas turbine system of claim 1 , further comprising a first bridge crane and a second bridge crane, both movable on the supporting frame.

7. The modular gas turbine system of claim 6 , wherein the first bridge crane and the second bridge crane are movable on common rails mounted on the supporting frame.

8. The modular gas turbine system of claim 6 , wherein at least one of the first bridge crane and second bridge crane is movable on rails extending substantially parallel to a rotation axis of the gas turbine engine.

9. The modular gas turbine system of claim 6 , wherein the first bridge crane is movable along first rails extending substantially parallel to the rotation axis of the gas turbine engine and the second bridge crane is movable along second rails extending substantially orthogonal to the rotation axis of the gas turbine engine.

10. The modular gas turbine system of claim 6 , wherein at least one of said first bridge crane and second bridge crane is movable on first rails extending substantially parallel to the rotation axis of the gas turbine engine and projecting horizontally beyond the footprint of the base plate up to a lay down area arranged on a side of the base plate.

11. The modular gas turbine system of claim 6 , wherein the first bridge crane has a lifting capacity higher than the second bridge crane.

12. The modular gas turbine system of claim 6 , further comprising a third bridge crane movably supported on the supporting frame.

13. The modular gas turbine system of claim 12 , wherein the first bridge crane and the second bridge crane are movably arranged on first rails supported by the supporting frame, the third bridge crane is movably arranged on second rails supported by the supporting frame, and the second rails are arranged above the first rails.

14. The modular gas turbine system of claim 1 , wherein the rotating load comprises at least one gas compressor.

15. The modular gas turbine system of claim 1 , wherein the modular gas turbine system is configured to be transportable.
