Smart design and functionality for your marine power grid
Our patented product E-PP is an electric, integrated diesel electric network and propulsion solution, which combines power generation, -distribution, -conversion as well as power supply for all consumers of the ship's network in one single system: technically and economically more efficient than any traditional DE (Diesel Electric) system.
In principle, this technology is suitable for all electric power supply and propulsion systems, particularly for those with strongly fluctuating load-profiles.
The E-PP solution are already in operation in more than 60 ships. The top 3 customer values of this system are:
- Lower fuel consumption and reduced emissions
- Increased safety and flexibility
- Space saving and easy installation
Less fuel and therefore less emissions
Due to the E-PP the combustion engines for the generators can be operated at their best possible level of efficiency, according to the power requirement – at any time and at any speed.
As a results a significantly lower fuel consumption is achieved compared to conventional diesel-electric propulsion systems. And thus the reduction of CO2 and NOx emission is achieved, contributing to EEXI / EEDI goals.
- Load dependent and fuel optimized power generation in real time
- Engines of generator sets are running in their most efficient speed range
- Increased efficiency for different operational profiles with variable speed drives
At any given moment the ship’s energy needs are automatically calculated and the diesel engines produce and supply only as much energy as needed. This allows the ship to use 20% less energy than a comparable ship.
Safe, reliable and more flexible than conventional system
The E-PP can be activated quicker than a conventional system: The generators can take over the load within just a few seconds, as synchronization is not needed. A clear advantage in terms of safety during onboard operation, particularly with fluctuating loads.
In addition the E-PP offers a high flexibility in terms of electrical power generation: From diesel, gas, LNG and/or shaft generators to battery systems.
Thanks to the overall concept, the systems ensures excellent maneuvering of the vessel. Furthermore have load variations and reverse power of drives and large consumers practically no influence on the ship´s networks.
More space and time for your products
The E-PP is designed to be a decentralized system, with space requirements reduced by fewer and smaller components compared to traditionaldiesel-electric propulsion systems.
The E-PP combines the main inverters of the electrical power generation systems and large consumers such as marine propulsion systems or the ship's bordnet in an optimized and integrated DC switchboard system. Due to the concept of the DC energy bus various components such as transformers, entire control cabinet sections and / or automation systems can be completely avoided or at least significantly reduced. The advantage of the E-PP is not only the reduced space requirement but also the reduced effort for integration engineering and the reduced costs for cabling and installation inside and outside the E-PP.
Benefits of the E-PP at a glance
All the sub systems are controlled and monitored independently by PLC , at the same time they are integrated together by the E-PP power management systems.
