Innovative, powerful, and efficient engines for diesel-electric propulsion
Electric propulsion is not a recent innovation, however it has become the “standard” propulsion solution in many applications, especially when it comes to specialized vessels. High redundancy and reliability of the propulsion plant, improved maneuverability of the ship, and lower fuel oil consumption due to optimized loading of the engines are the key. Diesel-electric systems by Everllence (former MAN Energy Solutions) are designed to meet customers’ highest requirements. Times are changing and thanks to new direct current (DC) components and an innovative engine control philosophy, diesel-electric propulsion has evolved, creating a much more compact solution with a range of potential applications.
