First Commercial Offshore Vessel to Validate ESS PerformanceTechnology
“When operating, for example, on dynamic positioning, there is a major fuel saving potential. When in harbour, too, the ship should be able to operate on the fuel cell and its battery power alone, which will reduce emissions significantly.” Bjørn-Johan Vartdal, Project Manager Det Norske Veritas (DNV)

A state-of-the-art super efficient offshore supply vessel, Eidesvik Offshore’s Viking Lady, is designed to safely service offshore installations in the extremely harsh waters of the North Sea. As the first merchant ship to use a fuel cell as part of its propulsion system, the Viking Lady was already one of the world’s most environmentally friendly ships. In the second phase of the project, the vessel was outfitted with a lithium ion battery pack to enhance efficiency further.For the third phase, a comprehensive field measurement program was conducted by Eidesvik and Wartsila during 2014/15. The Viking Lady achieved a fuel consumption reduction of 15% on average, showing strong performance in all operating modes. Phase 3 validates the worth of the hybrid OSV concept and indicated areas for improvement in ship system design and battery dimensioning.

The primary benefits of a hybrid system for a ship like the Viking Lady, is a 20-30% reduction in fuel consumption and CO2 emissions. This is achieved through smoother and more efficient operation of the engines. Compared to a traditional ship, the Viking Lady has reduced harmful NOx emissions by 180 tonnes, an amount equal to annual emissions from 22 000 cars. CO2 emissions are reduced by 15%.

The new DNV class rules for battery-powered ships have been developed in parallel to this project using Corvus Energy lithium polymer energy storage modules. These are the first ever class rules developed in order for batteries to be used as part of a vessel’s propulsion energy - both as hybrid solutions and for “pure” battery-driven vessels.
A comprehensive measurement program has been carried out to verify the fuel and emissions savings. The hybrid system will also be modelled in detail and will result in calibrated and verified process models to facilitate simulation and optimization of future hybrid systems.
Setting the Standard for Hybrid Solutions
A custom DNV EX Zone 1 enclosure was specified to house the energy storage system. Located on the foredeck, in an exposed area, the enclosure was built to withstand the rigours of life onboard a working offshore supply vessel in the North Sea.
