Wärtsilä Designs  Energy Storage Solution for North Sea Giant 

Finnish company, Wärtsilä, will retrofit the world’s first energy storage solution on board a large offshore supply vessel. The North Sea Giant, one of the world’s largest and most advanced subsea construction vessels, will be fitted with an energy storage system to reduce the vessel’s energy consumption, operating costs and exhaust emissions.

The North Sea Giant is a DP3 vessel. The ship is listed in the most advanced category of vessels that apply dynamic positioning. Installation of an energy storage solution into a class DP3 vessel has never been carried out before and requires a redefinition of applicable classification rules.

According to North Sea Shipping AS, the owner of the vessel , “The North Sea Giant is an efficient multi-purpose vessel with supreme deck and crane capacity, alongside a unique power system. Her propellers and thrusters are tailor made for delivering a wide variety of demanding marine operations in deep and ultradeep waters.”

Due to the innovative aspects of the project, Wärtsilä and North Sea Shipping AS are working in close collaboration with the DNV-GL classification society.

“Wärtsilä is the first in the world to work with hybrid systems on bigger vessels such as the DP3 classified North Sea Giant, and the project will set a new standard for this type of vessels,” said Cato Esperø, Director Sales Norway, Wärtsilä.

 “For us is it important to reduce environmental emissions and modernize the vessel to make it more competitive. In addition, with a more efficient vessel, we will save fuel expenses. Efficiency also saves time, because you only need to refuel every second or third port visit,” siad CEO of North Sea Shipping AS, Hallvard Klepsvik.

North Sea Shipping AS owns, operates and provides management services for advanced offshore supply vessels. Based in Austevoll on the west coast of Norway, the company has extensive experience in offshore shipping.
