Abstract: In a first embodiment, a system includes a turbine system including turbomachinery, one or more processors, and a memory storing instructions. When executed by the one or more processors, the instructions are configured to cause the one or more processors to receive an operating parameter of the turbomachinery, and calculate a risk of failure for the turbomachinery based at least in part on an asset failure mode model. The instructions are also configured to cause the one or more processors to categorize the risk of failure as a selected failure indicator category of a plurality of failure indicator categories, and output the selected failure indicator category.

Abstract: A method for assembling a gas or steam turbine is provided. The method includes providing an insulator and positioning the insulator between a vane support and a vane such that the insulator facilitates preventing hot gas migration into the vane, and such that during operation, hot gas is channeled from a high pressure side of the vane to a low pressure side of the vane. A vane assembly for a turbine rotor assembly is also provided. The vane assembly includes a vane support and an insulator including a projecting portion. The assembly also includes a vane. The insulator is coupled to the vane support such that the projecting portion is between the vane and a nozzle support strut to facilitate hot gas flow from a pressure side of the projecting portion to a suction side of the projecting portion.
