According to the agreement, the vessels will be converted into hybrid propulsion that will save fuel and reduce greenhouse gas emissions for two offshore supply vessels.

The vessels Ocean Star and Ocean Art will be equipped with the 746 kWh battery hybrid systems.

Wartsila and Wartsila engines designed the vessels. They are also equipped with Wartsila Low Loss Concept (LLC) electrical systems.

The LLC decreases electrical losses and provides increased individual engine loads, which leads to better fuel efficiency.

The company noted that with the installation of Wartsila hybrid battery upgrade, the integration with the current control systems will be seamless.

Atlantic Offshore CEO Roy Wareberg said: “Wartsila’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.

“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.”

Besides, Wartsila will also be responsible for the testing and sea trials of the technology after the installation.

The company expects the project to be completed early next year.

Earlier this month, Wartsila signed a contract with Norwegian shipping firm Eidesvik to supply hybrid technologies for Viking Neptun construction vessel.
