Flexibility and efficiency optimally combined

Reliability and reduced emissions

MAN Energy Solutions offers fully tailor-made propulsion and power generation solutions, including all components such as main engines, GenSets, switchboards, converters, electric motors, energy storage systems, gearboxes, and propellers. Hybrid propulsion optimizes the fuel efficiency of vessels that have a flexible power demand, such as fishing vessels, tugs, and RoPax. The combination of mechanical power from diesel engines and electrical power from electric motors guarantees the vessels a broad operational capability. Reliability is ensured by our all-round competence in the field.

This unites comprehensive technologies and competencies under one roof, including high- and medium- speed engines and GenSets, injection systems, turbochargers, control and after-treatment systems, as well as complete mechanical and electric power and propulsion trains.

Strong partners for strong performance

Together with Aspin Kemp & Associates (AKA), we provide complete system solutions for electric and battery hybrid propulsion. AKA’s specialized expertise is the integration of electric propulsion and energy storage systems as well as providing power management controls. In our battery hybrid propulsion solutions, the energy management system (EMS) controls the generation, storage, and distribution of power and energy, optimizing the overall performance of the propulsion system and increasing safety and system reliability. The EMS reduces life cycle costs and lowers fuel consumption. It also enables the smart application of emission-free and silent operation.

How you benefit:

  • Fewer NOx, SOx, and CO2 emissions
  • Zero-emission operation possible
  • Silent operation possible
  • Optimum efficiency thanks to extra flexibility
