Galleys and laundry onboard platforms, rigs, and supply vessels need to be equipped with the sturdiest and most heavy-duty equipment available. Electrolux is continually updating and refining its product range, and also focuses on hygiene, economics, safety, and after-sales service. www.electrolux-professional.com
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 by 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., necessita-ting an offline wash. The new system allows the turbine to be washed at part or base load without putting the operation at risk – and again, with consequent savings in water and components. www.gte.se
Riser/moorings analysis
Glisco Optekon provides OCED cost-effective design software to optimize design of the riser/floater/mooring system interaction for FPSOs. This software allows the user, for instance, to design a fatigue optimized floating system with steel catenary risers in deepwater. www.optekon.com
Semisubmersible design
GVA Consultants, one of the world's leading designers of semisubmersible platforms, has designed more than half of the purpose-built floating production units around the work, in addition to a large number of drilling and accommodation units. Currently, the company is engaged in four newbuild projects: Thunder Horse and Atlantis for BP, Kristin for Statoil, and Khazar for NIOC. www.gvaconsultants.com
