Norwegian operator Østensjø Rederi has selected Wärtsilä’s Hybrid Upgrade solution for retrofitting two offshore construction vessels.


The upgrades should lead to reduced use of the ships’ engine, correspondingly lower levels of exhaust emissions while operating in DP mode, and lower emission levels in all other operational modes.


Both the Edda Fauna and Edda Flora were built in 2008. Wärtsilä’s solution will include its new electronic DC bus-link, said to allow 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.


Reduced running of the engines saves fuel and lessens the carbon footprint, the company added, while engine maintenance requirements are also alleviated.


All equipment should be delivered in January.
