Gas Turbine Testing and Performance Benchmarking

A majority of gas compressors operating in the oil and gas fields are powered by gas turbines. Maintaining gas turbine performance is key to ensuring sufficient power is available from the engines to meet the compressor power demand. A lack of engine power reduces compressor capacity and can be a cause of compressor surging and failures.

Determining Performance of Existing Engines

Gas Turbine Performance is quite sensitive to power turbine operating speed and is also affected by a number of other factors such as:

	Ambient temperatures
	Pressure losses in the air filtration system
	Fouling of turbine air compressor
	HP turbine performance loss
	Power Turbine performance loss
	Inlet Guide Vane settings
	Blow off valve control system
	Combustion chamber and fuel quality

A good engine maintenance program is essential to manage the turbine performance and prevent excessive power losses. However, when operating a large fleet of gas turbines and compressors, frequently from different manufacturers, operators find it very difficult to keep up with OEM specified maintenance schedule. Operators require independent advice on gas turbine performance issues and especially the timing of engine overhaul because the cost of an engine overhaul is a major operating expenditure.

For existing projects with gas turbines, MSE provides a range of services to suit operating companies. These include:
 

	Testing and Monitoring Compressor and Gas Turbines performance trend
	Investigations of excessive engine power loss and restoration of engine power
	Engine life and overhaul schedule
	Advice on selecting, specifying and monitoring long term service agreements
	Performance testing and verifying engine IGV schedules and blow off valve
	Upgrade the control system which may become obsolete with time
