WÄRTSILÄ HYBRID

ENABLE FLEXIBLE DESIGN FOR THE FUTURE

Wärtsilä Hybrid

The introduction of Wärtsilä Hybrid and its integration with a conventional diesel or dual-fuel engine generating sets, offers significant efficiency improvement by running the engines on optimal load and absorbing many of the load fluctuations through batteries. The system is designed and integrated to optimise the overall operation of the vessel.

The power and energy capacity of the battery should be suitable to allow the engine to run for most of the time on optimal loads. A key element is hybrid control algorithms for load sharing between units and efficient power and energy management.

    Benefits
    • Fuel saving and reduced emissions
      Wärtsilä Hybrid ensures substantial reduction in emissions, and supports a sustainable operation with different fuels. The yearly fuel savings have proven to be between 10-20% depending on type of engines and configurations.
    • Optimized engine operation 
      Wärtsilä Hybrid supports operation of engines at optimal specific fuel consumption
    • Reduced engine transients 
      Wärtsilä Hybrid will be used to reduce transient loads in engines. Transients will increase fuel consumption and emissions.
    • Increased redundancy and efficient operations 
      Power redundancy requirements require engines to run at low loads. When energy storage is accepted as redundant power the engine will operate more efficient on higher loading.
    • Reduced maintenance
      Due to more stable operation and less running hours the maintenance cost will be reduced.
    • Increased performance
      Vessel performance will be more responsive due to the fast power response from the energy storage system. This may also increase dynamic performance in critical operations.
    Applications

    The Wärtsilä hybrid/battery system is suitable for application in a variety of market segments, including offshore vessels, tugs, ferries and coastal vessels, for new building as well as for retrofits of existing installations.

    Why hybrid marine power?

    The Wärtsilä hybrid system is designed and integrated to optimise the overall operation of the vessel. The system ensures fuel savings and reduced maintenance costs, in addition to substantial reductions in emissions. By increasing the power redundancy, the system allows the engine to operate closer to its optimum design point where it has highest efficiency and least emissions. This will result in reduced maintenance need and increased system performance. Rapid response from the battery system are also among the benefits offered.
