Wärtsilä Group has installed a hybrid energy system on board Norwegian offshore supply vessel (OSV) Viking Princess, making it the world’s first OSV with a hybrid energy storage solution.
The hybrid energy storage solution is a battery technology development in which batteries reduce the number of generators aboard a ship. It improves engine efficiency, generate fuel savings and reduce greenhouse gas emissions.
President Technical Department at Eidesvik Offshore, Vermund Hjelland said “Eidesvik and Wärtsilä’s partnership dates back to 2003 when our ship, the ‘Viking Energy’ became the first offshore supply vessel powered by LNG fuel. Now, together, we are again introducing a world’s first, with the ‘Viking Princess’ becoming the first offshore vessel in which batteries reduce the number of generators aboard the ship. We are grateful to Wärtsilä for providing the technology to make this possible,”.
Viking Princess reportedly completed its sea trials and the system was handed over to customer Eidesvik Offshore on 9 October 2017.
“There is significant potential to save fuel through improved engine efficiency, as the operating profile of supply vessels is highly variable.” Wärtsilä said.
Wärtsilä's energy storage system on board Viking Princess has fuel saving potential of up to 30 percent in various operations and the CO2 emissions can be reduced by up to approximately 13–18 percent per year, depending on operational conditions and requirements.
The company further said that the hybrid solution will provide a more optimal load on the engines, while the intervals between engine maintenance can be extended.
“This is a truly forward-looking solution, and we congratulate Eidesvik Offshore for having the vision to appreciate the benefits that hybrid energy system offers. 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,” says Sindre Utne, Manager Projects and Operations, Wärtsilä Norway.
Viking Princess now runs on a combination of a battery pack for energy storage and three LNG-fuelled Wärtsilä engines. The new energy storage solution provides balancing energy to cover the demand peaks, resulting in a more stable load on the engines.
