On/offline turbine cleaning
Gas Turbine Efficiency develops, makes, and markets systems for gas turbine cleaning with high efficiency, while minimizing impact on the environment through keeping CO2 and NOx levels as low as possible. The GTE concept provides a high degree of atomization of heated water or detergent through specially designed nozzles, operating at pressures of 50-80 bar. The benefits compared to lower pressure systems are improved wash efficiency, optimized use of water/detergent and use of the same nozzles for both on- and offline washes. The company's latest system is designed to minimize the need for revenue-losing, unscheduled shutdowns, i.e., necessitating an offline wash. The new system allows the turbine to be washed at part or base load without putting the operation at risk.
Mooring, vessel, riser analysis
Glisco Optekon's concept is to enhance profit by means of cost effective design. By using the Optecon Cost Effective Design software, it is possible to optimize profit (benefit-cost) of the riser-floater-mooring system for floating production systems. Thus it is possible to design a fatigue optimized floating system with steel catenary risers in deepwater.
