Identification and reduction of energy consumption. NOENCO points to IE3 onboard fishing vessel!
In industrial and marine applications electric drive units are responsible for 30% to 40% of all electrical energy generated. The entire drive system including the application is a significant factor regarding energy consumption and the saving potential is typically about 30% to 60%.
NOENCO undertakes a review of installations in fishing vessels, built in 2004, prior to EU-demands on efficiency classes for asynchronous motors.
NOENCO screening of savings that could be considered, switching from old electric motors to IE3-motors
NOENCO has selected 20 units based on usage, hours run per year and size.
What are the energy-savings related to changing electric motors to IE3 motors?
What are the energy-savings related to frequency regulation of pumps connected to engine installation?
Annual operation hours engine 6000 approx
Annual operation hours electric engines (IE3), mean value 4650 approx
A simple calculation on achieved savings upon completion in 1 year
- 18.000 litres of fuel – approx 183.000 kW
- Equivalent of 115.000 nkr/year
- TBT; 1.3 years
- Profit in 10 years; 1.700.000 mio nkr. / 185.000 Euro
Premium Efficiency – IE3 will become mandatory in Europe
Standard IEC 60034-30-1 defines energy efficiency classes for asynchronous motors.
Regulations (EC) 640/2009 and 04/2014 establish the conditions for converting towards the new energy-efficient technology.
