A Field Study of Reduced Axial Compressor Performance Deterioration through Online Washing and Air Intake Filtration Upgrade
Madsen, Stian (Doctoral theses at NTNU;2018:300, Doctoral thesis, 2018)Background Oil and gas production at several North Sea offshore installations is limited by the gas turbine power available, and any deterioration in gas turbine performance directly affects production rates. Fouling in ... -
An Experimental Investigation of Offshore Gas Turbine Intake Air Filter Performance
Brekke, Olaf (Doktoravhandlinger ved NTNU, 1503-8181; 2011:62, Doctoral thesis, 2011)Efficient intake air filtration is a key element for limiting fouling, erosion, and corrosion in the compressor section and hot corrosion in the hot section of offshore gas turbine installations. Current intake air systems ... -
Gas Turbine Intake Filters
Vasset, Peder Andreas (Master thesis, 2009)Energy offshore is mainly generated by gas turbines. Degradation of gas turbines is a source of considerable expenses for the oil and gas producing companies, and contributes to increased emissions to the atmosphere. ... -
Gas Turbine Optimum Operation
Flesland, Synnøve Mangerud (Master thesis, 2010)Many offshore installations are dependent on power generated by gas turbines and a critical issue is that these experience performance deterioration over time. Performance deterioration causes reduced plant efficiency and ... -
Gas Turbine Performance Deterioration
Verlo, Simen Berg (Master thesis, 2010)IToday, gas turbines are generally used to produce electricity and drive natural gas compressors on offshore installations. The performance of gas turbines is reduced gradually, and this lead to reduced production capacity ...
