Wärtsilä, a global leader in smart technologies and complete lifecycle solutions for marine and energy markets, will engineer, supply, and install complete battery hybrid packages to two offshore supply vessels (OSV) owned by the Norway-based operator Atlantic Offshore.

The upgrading works will be carried out at the Fitjar shipyard, Norway. By converting the vessels to hybrid propulsion, the owners will benefit through more economical fuel consumption and a reduced environmental impact.

The 746 kWh battery hybrid systems will be installed on the Ocean Star and Ocean Art. Both OSVs 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.

The technology group Wärtsilä will also execute the testing and sea trials for the systems after installation. The completion of the project for both OSV is planned in early 2020.
