Conversions of combustion and fuel systems Several of our Aalborg boilers like Aalborg D feature the unique pin tubes providing an extended heating surface. 6 Conversion projects Conversion of an oil tanker to an FPSO or FSO can involve changeover of fuel types from MDO and HFO firing to fuel gas and/or crude for existing Alfa Laval Aalborg or 3rd party brand boilers. Alternatively, new boiler systems complete with the required safety and control systems can be supplied. The inert gas system can be refurbished or replaced depending on the boiler solution chosen. Fuel conversions on existing boilers Our experience with conversion of fuel/burner systems on existing FSO and FPSO boilers dates back to the late 1980s. Alfa Laval provides design of steam propulsion, auxiliary and process applications for boilers ranging from 15–130 t/h, operating at pressures from 7–60 bar (g). We adopt a comprehensive approach to fuel conversion projects providing plan, design, manufacturing, installation, commissioning and approvals with the classification societies. Many times there is a need for Life Time extension programs and Alfa Laval is well versed to inspect, execute a gas study, report and if so required make changes / upgrades to the pressure part of the boiler Burners/combustion Alfa Laval has extensive combustion & burner design experience with marine combustion applications utilizing various fuels including gas, diesel oil, gas oil, and various heavy and crude oils. Although our burner designs are application and project specific, they are based on proven designs. GOSFERN™ combustion solutions come complete with fuel/air delivery modules and advanced safety and control based on TÜV approved safety PLC systems. The offshore oil and gas industry has come to recognize the need for better environmental control in addition to good flame stability, turndown and fuel efficiency. Alfa Laval recognizes the need to provide marine burner performance with pollution reduction techniques to meet global legislative requirements. The GOSFERN™ MPF burner is our basic marine dual fuel (gas and liquid) burner. We also supply a range of pollution-reducing marine burners GOSFERN™ MPF-LE. These burners have been tested under field conditions and proven suitable to meet current offshore standards.
