Abstract

The baseplate comprises a central elongate torsion and bending resisting member and at least a first load bearing cross-member, which extends transversely to the elongate torsion and bending resisting member. At least one machinery support platform is rigidly connected to the elongate torsion and bending resisting member and to the first load bearing cross-member. The elongate torsion and bending resisting member comprises vertically extending longitudinal lateral walls, where along auxiliaries of the rotating machinery are supported. The machinery support platform projects sideways beyond the longitudinal lateral walls of the elongate torsion and bending resisting member.

First claim

What is claimed is:

1. A baseplate for mounting and supporting rotating machinery, the baseplate comprising:
a central elongate torsion and bending resisting member;
at least a first load bearing cross-member extending transversely to the elongate torsion and bending resisting member; and
at least one machinery support platform rigidly connected to said elongate torsion and bending resisting member and to said first load bearing cross-member, wherein the rotating machinery is mounted on the at least one machinery support platform;
wherein said elongate torsion and bending resisting member comprises vertically extending longitudinal lateral walls, where along auxiliaries of said rotating machinery are supported;
wherein the machinery support platform projects sideways beyond the longitudinal lateral walls of the elongate torsion and bending resisting member; and
wherein the elongate torsion and bending resisting member has a vertical extension sufficient for an operator to access said auxiliaries maintaining an erected and ergonomic position and accessing a space underneath said machinery support platform.

2. The baseplate according to claim 1 , wherein said lateral walls are planar.

3. The baseplate of claim 1 , wherein said at least one load bearing cross-member has vertically extending lateral walls for supporting auxiliaries of the rotating machinery.

4. The baseplate of claim 1 , further comprising at least an additional cross-member, extending parallel to said first load bearing cross-member and distanced therefrom along the longitudinal extension of the elongate torsion and bending resisting member.

5. The baseplate of claim 1 , wherein the elongate torsion and bending resisting member has a box-shaped structure.

6. The baseplate of claim 1 , further comprising only three spaced support members, one of said support members being connected to a bottom surface of the elongate torsion and bending resisting member and two of said three support members being connected to a bottom surface of the first load bearing cross-member, in respective positions generally symmetrical with respect to the elongate torsion and bending resisting member.

7. The baseplate of claim 1 , wherein said machinery support platform projects in an overhanging manner from one longitudinal end of said elongate torsion and bending resisting member.

8. The baseplate of claim 1 , wherein said auxiliaries include one or more of the following: a fuel skid; a turbine starter; a lubrication oil tank; lubrication oil filters; lubrication oil pumps; vapor separator for the oil tank; lubrication oil heat exchangers; or electric control panels.

9. A turbomachinery system comprising:
rotating machinery including at least a gas turbine and a load driven in rotation by said gas turbine; and
a baseplate comprised of:
a central elongate torsion and bending resisting member;
at least a first load bearing cross-member extending transversely to the central elongate torsion and bending resisting member, the central elongate torsion and bending resisting member extending generally parallel to a rotation axis of the gas turbine; and
at least one machinery support platform rigidly connected to said elongate torsion and bending resisting member and to said first load bearing cross-member, whereon the rotating machinery is constrained and supported, wherein the rotating machinery is mounted on at least one machinery support platform;
wherein said elongate torsion and bending resisting member comprises vertically extending longitudinal lateral walls, where along auxiliaries of said gas turbine are supported;
wherein the machinery support platform projects sideways beyond the longitudinal lateral walls of the elongate torsion and bending resisting member; and
wherein the elongate torsion and bending resisting member has a vertical extension sufficient for an operator to access a space underneath said machinery support platform where said auxiliaries are located, maintaining an erected and ergonomic position.

10. The system of claim 9 , wherein the turbine is housed in a turbine acoustic enclosure, which projects in an overhanging manner beyond a longitudinal end of said elongate torsion and bending resisting member.

11. The system of claim 9 , wherein the load comprises a centrifugal compressor, pump, or an electric generator.

12. The system of claim 9 , wherein said rotating machinery comprises a speed reducer or multiplier load gear arranged between the gas turbine and the load, said speed manipulating device including an inlet shaft drivingly connected to the gas turbine and an output shaft drivingly connected to the load.

13. The system of claim 12 , wherein the inlet shaft and the outlet shaft of
said speed reducer or multiplier load gear are arranged in vertical superposed relationship, minimizing a transverse dimension of the machinery support platform.

14. The system of claim 9 , wherein said longitudinal lateral walls of the elongate torsion and bending resisting member are planar.

15. The system of claim 9 , wherein said at least one load bearing cross-member has vertically extending lateral walls for receiving auxiliaries of the rotating machinery.

16. The system of claim 9 , wherein said baseplate further comprises at least an additional cross-member, extending parallel to said first load bearing cross-member and distanced therefrom along the longitudinal extension of the elongate torsion and bending resisting member.

17. The system of claim 9 , wherein the elongate torsion and bending resisting member has a box-shaped structure.

18. The system of claim 9 , further comprising only three spaced support members, one of which is connected under the elongate torsion and bending resisting member and the other two are connected under the first load bearing cross-member, in respective positions generally symmetrical with respect to the elongate torsion and bending resisting member.
