DORKING, UK -- Frazer-Nash has completed work on a ventilation system for three gas turbine enclosures on Nexen's Scott platform in the UK central North Sea.
The engineering consultancy analyzed temperature distribution, comparing this with the cooling needs of the upgraded control equipment within the enclosures. Based on its findings, it then re-designed the ventilation system to ensure the operating environment accorded with the equipment's thermal requirement.
Using computational fluid dynamics models of the gas turbines and their enclosures, Frazer-Nash simulated the heat loading and ventilation flow through the enclosures to identify regions that required modification. Subsequently it designed ventilation duct work to increase the rate of ventilation flow and cooling efficiency in the enclosures, while maintaining the existing cooling fans.
The company worked closely with American Air Filters to support manufacture of the new ventilation system. Nexen has since contracted it for further work on its Scott and Buzzard platforms.
