CENTRIFUGAL COMPRESSOR MAINTENANCE AND FAILURE ANALYSIS

DESCRIPTION

Compressors are common in almost all industrial systems and applications.Compressors represent a significant part of capital and operating costs on most plants. Gas turbine is a major power source used in the generation of electricity, and the driver of choice for modern aircraft, pumps, compressors ......etc. This training course covers main topics of operation and maintenance of gas compressor and turbines and associated support systems. In addition, the course develops a background in gas turbine operation that enables participants to analyze operating problems properly and take the necessary corrective action. The course combines between the basic and practical considerations related to centrifugal compressors. The use of gas turbines in the petrochemical, power generation and offshore industries has increased considerably during the past few years.  The course will cover the design, installation, operation and maintenance of these machines by highlighting characteristics features, efficiencies, reliability and maintenance implications. Upon completion of this course, participants will gain a complete and up-to-date overview of the Gas Turbine technology. A Vibration- Monitoring system gives warnings when vibration levels reach a preset level, and hence provides a round- the - clock watch on vital machinery. The training course aims to provide a treatment of the detection and diagnosis of faults in rotating equipment using vibration measurement and analysis

OBJECTIVES

The course will cover the construction, operation and maintenance of these machines by highlighting characteristics features, efficiencies, reliability and maintenance implications. Upon completion of this course, participants will gain a complete and up-to-date overview of the centrifugal compressor and Gas Turbine technology and be familiar with all operation and maintenance requirements.

• Learn the principles of the centrifugal compressors and gas turbine.
• Familiarize the participants with various types of centrifugal compressor & gas turbine.
• Understand the operation principles of the centrifugal compressor and gas turbine.
• Learn the maintenance procedure of the centrifugal compressor and gas turbine.
• Discuss the troubleshooting and failure analysis of the centrifugal compressor and gas turbine.

PARTICIPANTS

                Turbine & compressor maintenance engineers of relatively short experience and senior technicians of medium experience who have the ability to improve & develop their capabilities. Members of the following departments: Engineering, Planning, Procurement, Operation, Maintenance or Inspection and those who are engaged in or intend to be familiar with compressor systems. Also senior staff  should update and refresh their knowledge by attending this course.

TRAINING METHODOLOGY

A highly interactive combination of lectures and discussion sessions will be managed to maximize the amount and quality of information and knowledge transfer. The sessions will start by raising the most relevant questions, and motivate everybody find the right answers. The delegates will also be encouraged to raise their own questions and to share in the development of the right answers using their own analysis and experiences. Tests of multiple-choice type will be made available on daily basis to examine the effectiveness of delivering the course.

Competencies Emphasized

• Understanding of monitoring techniques as applied to compressors and turbines.

• Ability to put in place measures to quantify equipment condition.
• Interface with and control service providers.
• Identify and specify new compressor and turbine plant.
