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:
