(OPS201.4) Gas Turbine Operations Review - W Units
Designed to increase the knowledge base of operations personnel who are ready for more detailed instruction on Gas Turbine theory of operation and practical application.
Description
The Siemens Energy Gas Turbine Operations Review course is developed for the experienced operator. The course is designed to increase the knowledge base of operations personnel who are ready for more detailed instruction on Gas Turbine theory of operation and practical application. The student will review the combustion process in detail and then understand how parameter changes affect the overall efficiency and operation of the turbine. A refresher in the T3000 control system will bring together these concepts and teach the operator to utilize the control system to monitor efficiency, find problems, and assess risk. A combination of classroom training with T3000 walkthroughs is used to maximize training value.
The first step to maximizing operational efficiency is to understand the process in detail and then applying that knowledge. The Siemens Energy Gas Turbine Operations Refresher course trains plant personnel to take that step.
All training programs are limited to the Siemens Energy scope of supply.
