    Wärtsilä makes Viking Princess the world's first offshore vessel with a hybrid energy storage solution replacing a traditional generator

    The technology group Wärtsilä reached a new milestone in the battery technology development as the company completed the installation of a hybrid energy system on board Viking Princess, the company said in its press release. The Norwegian vessel is now the first ever offshore supply vessel in which batteries reduce the number of generators aboard the ship. The new energy storage solution will improve engine efficiency, generate fuel savings and reduce greenhouse gas emissions. Viking Princess completed sea trials and the system was handed over to customer Eidesvik Offshore on 9 October 2017.
     
    There is significant potential to save fuel through improved engine efficiency, as the operating profile of supply vessels is highly variable. When using the Wärtsilä installed energy storage system on board Viking Princess, the fuel saving potential can be up to 30 percent in various operations and the CO2 emissions can be reduced by up to approximately 13-18 percent per year, depending on operational conditions and requirements.
     
    Furthermore, the hybrid solution will provide a more optimal load on the engines, while the intervals between engine maintenance can be extended.
     
    Viking Princess now runs on a combination of a battery pack for energy storage and three LNG-fuelled Wärtsilä engines. The new energy storage solution provides balancing energy to cover the demand peaks, resulting in a more stable load on the engines. The technology is similar to that used in hybrid vehicles: it prevents the engine load from dipping, and uses the surplus to re-energise the battery, which can be charged as needed. Wärtsilä's remote monitoring and operational advisory services support the daily operation of the vessel ensuring efficient and optimised operations.
     
    The contract to replace one of the four engines on Viking Princess with battery power was signed in May.
     
    Wärtsilä in brief:
    Wärtsilä is a global leader in advanced technologies and complete lifecycle solutions for the marine and energy markets. By emphasising sustainable innovation and total efficiency, Wärtsilä maximises the environmental and economic performance of the vessels and power plants of its customers.

Wärtsilä is listed on Nasdaq Helsinki, Finland.
