Wärtsilä has completed the installation of a hybrid energy system on-board an offshore supply vessel operated by Norway-based Eidesvik Offshore.
The system was installed as part of an agreement signed between the companies in May to replace one of Viking Princess’ four engines with a hybrid energy system.

The solution is expected to improve engine efficiency, conserve fuel and reduce greenhouse gas emissions from the ship.
In addition, the hybrid energy storage system is designed to prevent the engine load from dipping and uses the surplus energy to re-energise the battery, which can be charged as and when required.
Viking Princess has recently completed sea trials, and could be able to save up to 30% fuel and reduce its annual carbon dioxide (CO2) emissions by around 13%-18% in certain operating conditions by using the system.
The vessel will also be able to carry out its operations with a combination of a battery pack for energy storage and three Wärtsilä engines, which are powered by liquefied natural gas (LNG).

By GlobalDataWärtsilä Norway Projects and Operations manager Sindre Utne said: “In addition to the fuel consumption and environmental advantages, the conversion also reduces maintenance costs and contributes to more efficient operations.
“The success of this project will impact the future of the entire shipping industry.”
Wärtsilä was also selected to provide re-liquefaction plants for three new LNG carriers in August.
One of the contracted ships is being built at the Samsung Heavy Industries (SHI) yard in South Korea for Gaslog, while the other two units are being constructed for Norway-based Knutsen at the Hyundai Heavy Industries (HHI) yard in South Korea.
