Turnkey integrated solutions

Electric propulsion is becoming more popular and its use is spreading to all types of vessels.

 The main features of our electric propulsion system are:
• Excellent maneuverability of the vessel.
• Reduced noise and vibrations. 
• More available space in the vessel for the cargo area. 
• Flexibility in the location of the propellers. 
• Improved life cycle cost, especially when there are large variations in load demand.
 
As designers and manufacturers of frequency converters, and motors and generators, we can define its basic parameters in order to achieve the optimal result for the whole installation, maintaining levels of short circuit, harmonics, etc. at its optimal level, so we provide in a single package all components of the system:
• Generators
• Transformers  (when required)
• Electric switchboards
• Frequency converters
• Motors 

Additionally, from years ago, we provide the AFE (Active Front End ) type frequency converters, achieving the following improvements over traditional systems:
• No need for installation of transformers, which saves space and weight.
• The ability to regenerate power to the grid, so no need for braking resistors. 
• Very low harmonics, without installation of additional transformers or harmonic filters.
• Power factor 0.99, which allows a better use of the generators.

From Ingeteam we offer different configurations depending on the needs of each project:
• Low and medium power: Low Voltage System  (690 V).
o With transformer:  12-pulse converters, quasi 24 and 24 pulses.
o Without transformer:  AFE converters (Active Front End). 
o Power for each propulsion motor up to 5 MW.

• High power: Medium Voltage System (6.6 kV and 3.3 kV).
o With transformer:  12-pulse converters, quasi 24 and 24 pulses.
o Without transformer:  AFE converters (Active Front End). 
o Power for each propulsion motor up to 24 MW.
