Østensjø Rederi AS has christened their new offshore construction vessel, »Edda Freya«. This new vessel was designed and built for[ds_preview] the Greater North Sea market and utilizes an environmentally friendly and fuel saving diesel electric hybrid propulsion system powered by a Corvus Energy ESS (Energy Storage System). The subsea construction vessel was designed with a focus on cable laying operations, offshore construction and IMR operations. »The fuel saving, environmentally friendly propulsion system (Siemens BlueDrive PlusC) was implemented by Siemens in cooperation with Østensjø Rederi. By using variable rotational speed with optimal operation of the diesel generators in combination with the Corvus ESS, the system will significantly reduce fuel consumption and the emissions of nitrogen oxides (NOx) and greenhouse gasses (CO2/methane),« Corvus said.
