Eta Technologies LLC is a Connecticut (USA) based company providing engineering consulting services and replacement parts for the land-based industrial gas turbine (IGT) industry. The company was formed in 2004 by the two principals, namely John Kearney and Richard Curtis. During their previous employment with various IGT parts and service providers, these two engineers developed and implemented component repairs, upgrades and new aftermarket parts for a wide variety of power generation gas turbines, and provided technical assistance to clients involved in gas turbine operations and maintenance. Also in this prior employment, specialty or “niche” capabilities were developed with respect to Siemens V-series engines, in which extensive experience with component repairs and upgrades was gained, and sources developed for manufacture of many of the capital and consumable parts utilized in these gas turbines. With the founding of Eta Technologies, an independent and experienced provider of gas turbine engineering consulting services was thus established, with a particular specialty in parts manufacture and repair/coating/upgrade services for “V” series machines. Eta Technologies LLC offers services for all types of gas turbines, especially in the areas of gas turbine condition assessment, borescope inspections, component manufacture, repair, root cause analyses and metallurgical evaluations. The company offers outage technical support, critical component assessment, metallurgical expertise and assistance with parts manufacture and repair, serving either as prime contractor or providing technical/commercial guidance.
