Training Certificate

Prolific Consultants FZE Certificate of Course Completion will be issued to all attendees.

Course Introduction

Gas Turbine Training classes provide technical information for those people who maintain the gas turbine engines. The goal of each training program is to build confidence based on knowledge and understanding. Engine System Familiarization and Maintenance Procedures are key focal points of each program. This training is built on a foundation that will enable the student to understand:

• Engine Nomenclature & Functions
• Engine Systems Operation
• Gas Turbine Principles and Theory
• Troubleshooting Techniques Through Class Discussions
• Maintenance and Preventative Maintenance
• Inspection technique

Course Objective

The objective of this course is to give participants an understanding of basic gas turbine operations and construction as well as a fundamental knowledge of proper operation, control and protection of the turbine and its accessory systems.

Emphasis is placed on the following areas:

• Basic gas turbine operating cycle
• Overview of gas turbine major components and equipment arrangements and how these relate to overall operation and performance
• Fundamentals of gas turbine control and protection: start-up, speed, load, shutdown and temperature
• Operating parameters and control / protection features of the various turbine support systems such as the lubricating oil, hydraulic, variable inlet guide vanes, starting means and fuels
• Operating factors and considerations that affect maintenance intervals

Suitable For

Operators, engineers, technicians, and administrative personnel of operating facilities as well those who may work in affiliated industries, who wish to gain an understanding of the day-to-day operation of heavy duty gas turbines.

Training Methodology

A highly interactive combination of lecture and discussion sessions will be managed to maximize the amount and quality of information, knowledge and experience transfer. The sessions will start by raising the most relevant questions, and motivate everybody finding the right answers. The attendants will also be encouraged to raise more of their own questions and to share developing the right answers using their own analysis and experience.

All presentations are made in excellent colorful power point. Very useful Course Materials will be given.

• 30% Lectures
• 30% Workshops and work presentation
• 20% Group Work & Practical Exercises
• 20% Videos & General Discussions
