A piping assembly and a method for connecting an inner shell and an outer shell in a turbine system are disclosed. The piping assembly includes an inner fitting for connection to the inner shell and an outer fitting for connection to the outer shell. The piping assembly further includes an attenuation member extending between the inner fitting and the outer fitting and comprising an attenuation curve. The attenuation curve permits movement of the attenuation member in at least one of a longitudinal direction, a radial direction, or a tangential direction.

1. A piping assembly for connecting an inner shell and an outer shell in a turbine system, the piping assembly comprising: an inner fitting for connection to the inner shell;an outer fitting for connection to the outer shell; andan attenuation member comprising an inner portion coupled at a first end to the inner fitting, a U-shaped attenuation curve and an outer portion coupled at a second end to the outer fitting, wherein both the inner portion and the outer portion extend circumferentially about the inner shell arid the outer shell substantially parallel to each other and substantially perpendicular to a longitudinal axis of the turbine system, the attenuation curve permitting movement of the attenuation member in at least one of a longitudinal direction, a radial direction, or a tangential direction. 2. The piping assembly as in claim 1, wherein the attenuation curve permits movement of the attenuation member in a plurality of directions. 3. The piping assembly as in claim 2, wherein the directions include the longitudinal direction and the radial direction. 4. The piping assembly of claim 1, further comprising a plurality of inner fittings. 5. The piping assembly of claim 1, further comprising a plurality of outer fittings. 6. The piping assembly of claim 1, wherein the inner fitting is fixedly connectable to the inner shell. 7. The piping assembly of claim 1, wherein the outer fitting is movably connectable to the outer shell to accommodate loading in at least one of the longitudinal direction, the radial direction, or the tangential direction. 8. The piping assembly of claim 7, wherein the outer fitting is movably connectable to the outer shell to accommodate loading in the radial direction. 9. The piping assembly of claim 1, wherein the outer fitting comprises an outer flange, an insert, and an inner flange. 10. A turbine system, comprising: an inner shell;an outer shell at least partially surrounding the inner shell; anda piping assembly connecting the inner shell and the outer shell, the piping assembly comprising: a first inner fitting connected to the inner shell;a second inner fitting connected to the inner shell;an outer fitting connected to the outer shell; andan attenuation member comprising an inner portion coupled at a first end to the first inner fitting and at a second end to the second inner fitting, an attenuation curve which extends between the inner portion and the outer portion, wherein the inner portion and the outer portion extend circumferentially about the inner shell and the outer shell substantially parallel to each other and substantially perpendicular to a longitudinal axis of the turbine system, the attenuation curve extending circumferentially and longitudinally between the inner and outer portions, wherein the attenuation curve permits movement of the attenuation member in at least one of a longitudinal direction, a radial direction, or a tangential direction. 11. The turbine system of claim 10, wherein the attenuation curve permits movement of the attenuation member in a plurality of directions. 12. The turbine system of claim 11, wherein the directions include the longitudinal direction and the radial direction. 13. The turbine system of claim 10, wherein the inner fitting is fixedly connected to the inner shell. 14. The turbine system of claim 10, wherein the outer fitting is movably connected to the outer shell to accommodate loading in at least one of the longitudinal direction, the radial direction, or the tangential direction. 15. The turbine system of claim 14, wherein the outer fitting is movably connected to the outer shell to accommodate loading in the radial direction. 16. The turbine system of claim 10, wherein the outer fitting comprises an outer flange, an insert, and an inner flange. 17. The turbine system of claim 16, wherein the insert and inner flange each include mating threads. 18. The turbine system of claim 16, wherein the outer flange contacts an outer surface of the outer shell, the inner flange contacts an inner surface of the outer shell, and the insert extends between the outer flange and the inner flange. 19. A method for connecting an inner shell and an outer shell in a turbine system, the method comprising: connecting an inner fitting of a piping assembly to an inner shell, the piping assembly comprising the inner fitting, an outer fitting, and an attenuation member extending therebetween, the attenuation member comprising an inner portion coupled at a first end to the inner fitting, an attenuation curve and an outer portion coupled at a second end to the outer fitting, wherein both of the inner portion and the outer portion extend circumferentially about the inner shell and the outer shell substantially parallel to each other and substantially perpendicular to a longitudinal axis of the turbine system, the attenuation curve permitting movement of the attenuation member in at least one of a longitudinal direction, a radial direction, or a tangential direction, the outer fitting comprising an outer flange, an insert, and an inner flange;coupling the inner shell with an outer shell;inserting the insert of the piping assembly through the outer shell; andconnecting the outer fitting to the outer shell. 20. The method of claim 19, wherein the inner fitting is fixedly connected to the inner shell and the outer fitting is movably connected to the outer shell.
