Wartsila Hybrid Upgrades for Two Ostensjo Rederi Vessels

The Wartsila Hybrid Upgrade solution has been selected for retrofitting two offshore construction vessels owned by Norwegian operator Ostensjo Rederi.

The Wartsila Hybrid Upgrade solution has been selected for retrofitting two offshore construction vessels owned by Norwegian operator Ostensjo Rederi. The upgrading project will allow less use of the ships’ engines with correspondingly lower levels of exhaust emissions while operating in dynamic positioning mode, and will also lower emission levels in all other operational modes. The order with the technology group Wärtsilä was placed in the third quarter of 2020.

The two ships, the ‘Edda Fauna’ and ‘Edda Flora’, were built in 2008. The customer opted for the Wärtsilä Hybrid Upgrade solution in order to give the ships a more attractive environmental profile for potential charterers. The Wärtsilä Hybrid Upgrade solution will include the company’s new electronic DC bus-link, which allows a vessel to operate in DP 2 and 3 modes with a closed DC bus in hybrid, and an open bus on the AC system. The reduced running of the engines saves fuel and lessens the carbon footprint, while engine maintenance requirements are also alleviated.

Delivery of the Wärtsilä equipment to both vessels is planned for January 2021.
