  8. Lube Oil Requirements
    1. Engine lube oil must be in accordance with requirements as stated in section 9.1.1
    2. Viscosity class (40°): SAE40
  9. Cooling System
    1. Cooling method: radiator
    2. Cooling system designed for cooling water in accordance with requirements as stated in section 9.1.2
    3. Engine cooling water circuits without glycol content considered
  10. Fuel System
    1. Fuel gas system designed based on natural gas and pilot fuel oil in accordance with requirements as stated in section 9.1.6
    2. Engines can be operated on diesel fuel oil in accordance with requirements as stated in section 9.1.3
    3. Engines can be operated on heavy fuel oil in accordance with requirements as stated in section 9.1.4
    4. Below 10% engine load, the engine will be operated on diesel oil
    5. Different lube oil qualities (for HFO/gas operation) are required; installation of two independent lube oil storage tanks is recommended
  11. Intake Air and Ventilation
    1. Ambient air: free of dust, salt and sand, aspirated from outside power house
    2. Intake air must be in accordance with requirements as stated in section 9.1.7
    3. Power house ventilation air is blown directly onto the alternator
    4. Maximum temperature inside power house at floor level next to engine/alternator: 55 °C (Tambient + 10 K)
    5. At gallery level, temperature of 60 °C (Tambient + 15 K) is permissible
    6. Alternator design temperature: 48 °C
  12. Frequency and Load Limits
    1. Maximum continuous engine output ensured at mains grid frequency exceeding up to max. +3%
    2. At frequency drop to max. -5%, power output continuously reduced to 95% MCR
    3. Operation permitted up to +5% frequency fluctuations for maximum 120 seconds
    4. Maximum permissible mains grid frequency deviation: ±5%
    5. In grid parallel operation, frequency varies according to current consumer load and input from power suppliers
  13. Power Fluctuations
    1. Power train of generating set acts as a torsional vibration system consisting of engine, coupling and generator
    2. Reciprocating engine, power grid, and other consumers and producers excite the system
    3. Active power at generator terminals is not completely constant; additional power oscillations occur
    4. Power fluctuations do not affect operational safety of the generating set
    5. Behavior is in accordance with ISO 8528-5 and does not affect net stability in an unacceptable range
    6. Gas operated engines tend to show higher load fluctuations than engines operated on diesel fuels
