2x 3,06 MWe Ulstein Bergen Gas Engines Technical description of the Power Plant Power Capacity: (25 °C): 2 x 3,06 MW / 3,8 kVA Type of engine: Ulstein KVGS 18-G1 Voltage out of Generator: 11 kV Frequency: 50 HZ / 1500 rpm Fuel System: Naturel gas (LHV 39,6 in DK) Operating hours: Aprox. 40.250 The engines have always been fueled with Danish Natural gas, with a LHW of 39,6 kJ/Nm3. There are gas lines, approved by the gas authorities. The engines are with air start, and starting air tank is included. The control system is rebuilt in 2006, and the PLC was changed. Engine/generator drive connection is flexible. Generators with two bearings. 11 kV generator breakers and relay setup according to the Danish TSO technical description. Total starting time is 12 min. From starting signal to full power. Scope of supply: 2x Ulstein Bergen lean burn gas engines / alternators 2x Ventilation system, exhaust gas system, silencers, stack (year 2006), starting air compressor, control and power panels, gas lines and gas equipment. Fact sheet Bergen KV-G4.2 The latest lean-burn K-gas engine Cost-efficiency: High electrical efficiency will reduce fuel cost. Together with the advantage of the medium speed engine concept this results in low life-cycle cost. Reliability: The KV-series of lean-burn gas engines are based on a marine design with an Higher efficiency and reliable operation. extremely successful track record. Together with our The KV-G4.2 lean-burn gas engine is The KV-G4.2 fulfils the customers’ long experience in gas engine taking advantage of state-of-the-art demand for high power output with technology, we can offer a control and combustion technology. low emissions and the best fuel well-proven medium speed efficiency. solution, which will secure combustion chamber and using Miller The ignition system controls each your investment. Timing, the KV-G4.2 has the highest cylinder individually, further improving electrical efficiency in its range. Today’s engine availability. Combustion air is KV-G4.2 is a result of 15 years of controlled by variable geometry, giving commercial operation and experience optimum volume of compressed air combined with the continuous effort and increase in the exhaust from Rolls-Royce to further develop temperature. Due to an optimised design of the the lean-burn gas engine technology.
