Norway-based operator Atlantic Offshore has confirmed it is to convert two of its offshore supply vessels (OSVs) to hybrid propulsion using Wärtsilä’s battery hybrid packages.

The conversion will help the vessels reduce fuel consumption and environmental impact. 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.

The upgrading project will be carried out at the Fitjar shipyard in Norway.

“Wärtsilä’s Smart Marine approach, with its focus on greater efficiencies and better environmental performance, is an important background to this upgrading project for these two vessels. In addition to saving fuel and reducing greenhouse gas emissions, the hybrid package will make the vessels more attractive to potential charterers,” said CEO Roy Wareberg, Atlantic Offshore. “Atlantic Offshore is committed to promoting sustainability throughout our operations and having the ‘Ocean Star’ and ‘Ocean Art’ converted to hybrid propulsion is fully in line with this commitment. We thank Wärtsilä for its excellent support and capabilities in bringing this project to reality.”

Wärtsilä will also carry out the testing and sea trials for the systems following installation. The order with Wärtsilä was placed in June 2019 and completion of the project for both ships is expected in early 2020.
