Shipowners are shifting towards hybridised and electrified vessels as they slow down and adopt clean technologies. This takes them further towards full electrification, with many options along the way.

Some recent Wärtsilä projects demonstrate the variety of hybridisation solutions available to shipowners. Three new Finnlines roros have 2-stroke engines, shaft generators, PTO/PTI, thrusters with controllable pitch propeller as well as an energy management system, power management system and automation system. The vessel can manoeuvre on battery power, avoiding emissions close to port.
