The ST18 power generation package is a fully-integrated modular system which can be installed offshore to generate ultra-low-cost ancillary power directly from excess gas production.
The self-contained package can generate approximately 2MW of electrical power at 600V, making a significant contribution towards a reduction in installation operating costs (eg. by cutting diesel consumption) while at the same time improving overall environmental performance by reducing flaring.
Alba Power’s ST18 package is based on the Pratt & Whitney gas turbine engine,
which features high efficiency with low maintenance requirements
Alba Power’s ST18 module has just been completed at base and is available for immediate viewing & dispatch.
The module’s 2MW output (generated directly from excess gas production) was designed to contribute to significant reductions
on the platform’s operating costs by reducing both the running costs and the maintenance costs of the installation’s conventional power generators.
Alba Power supplies a full turnkey installation service for the ST18 power generation package with optimised commissioning time and a wide variety of service options.

The Pratt & Whitney ST18 gas turbine engine
The ST18 gas turbine is a derivative of the PW100 turbo-prop aircraft engine, of which there are over 4800 in current flight service with over 100 million hours of operating time worldwide.
Internal aerodynamic parts in the new ST18 engines are common with the flight engines.
The turbine combines the highest efficiency in its class with low maintenance costs, and features a twostage centrifugal compressor with 30.2% overall efficiency.
-HP compressor 33,000rpm
-LP compressor 27,700 rpm
The control system
The Allen Bradley PLC integrated control system incorporates a high-reliability industrial programmable logic controller with easy access system screens for operations data, diagnostic screens, trend monitoring/alarm and trip information.
The control system also features advanced DSLC™ for automatic synchronisation and load share with the installation electrical system.
The control package is supplied by Alba Power on-site, fully tested and ready for use.
