Edda Fauna goes green.
EDDA FAUNA AND EDDA FLORA INSTALL BATTERIES Edda Fauna and Edda Flora will become greener and more attractive to an offshore market reaching for reduced emissions. Both vessels are going through something of a midlife improvement to increase their competitiveness in today’s market and in the future second-hand market. The company’s policy is to operate the vessels for 20-25 years. - In this case it makes sense to install batteries as a part of the ships’ energy systems, says leader of the project department, Egil Arne Skare. The goal is to implement it in a way that retains their available main deck space. - That’s what makes this a challenge. We can’t just place a container on deck, like you often do on a PSV. On Edda Fauna and Edda Flora, a solution like that would reduce its operability, so the batteries have to be installed below deck. We can’t allow an installation like this to reduce the capacity for our clients, he explains.
PROJECT STARTS AFTER NEW YEARS

nology, and have landed on Wärtsilä Norway from Stord as our supplier. They have developed the package we need. The installation will be performed on both ships simultaneously at Westcon Yards. It’s a comprehensive job that will be completed after New Years, when the ships are scheduled for planned maintenance. - Wärtsilä is an integrator; in addition to the battery systems, they also deliver the control systems for the power electronics. This is going to be upgraded and integrated with the DP-system delivered by Kongsberg. The batteries are bought externally. - And the integration of batteries won’t lower the ships’ effectiveness? - No, they’ll be dimensioned for the performance demanded of them, says Skare. He points out that this is all part of a green shift that other Norwegian shipping companies have done before them, and that Østensjø now are ready to go through with, even upgrading ships built when this kind of technology was not available.
