The technology group Wärtsilä will engineer, supply, and install complete battery hybrid packages in two offshore supply vessels owned by the Norway-based operator Atlantic Offshore. The upgrading project will be carried out at the Fitjar shipyard in Norway.
By converting the vessels to hybrid propulsion, the owners will benefit through more economical fuel consumption and a reduced environmental impact. The order with Wärtsilä was placed in June 2019.

The 746 kWh battery hybrid systems will be installed on the Ocean Star and Ocean Art. Both ships were designed by Wärtsilä, and are fitted with Wärtsilä engines and Wärtsilä Low Loss Concept (LLC) electrical systems.
The LLC reduces electrical losses and delivers higher individual engine loads to provide better fuel efficiency. By selecting Wärtsilä for the hybrid battery upgrading, the integration with the existing control systems will, therefore, be seamless.
Wärtsilä will also carry out the testing and sea trials for the systems following installation. Completion of the project for both ships is expected in early 2020.
