M/S Viking Grace equipped by Wärtsilä
Wärtsilä has supplied four Wärtsilä 8L50DF main engines, the transverse bow and stern tunnel thrusters, and two stainless steel fixed pitch, built-up main propellers with complete propeller shaft lines and environmentally sound shaft line seal systems for M/S Viking Grace. The propellers are designed with the lowest possible pressure impulses for superb vibration control.
The vessel will be fuelled by liquefied natural gas, meaning that sulphur oxide emissions will be almost zero, and nitrogen oxide emissions will be at least 80 per cent below the International Maritime Organization’s (IMO) current stipulated level. Furthermore, there is a reduction of particulate emissions of more than 90 per cent compared to the emissions from conventional diesel engines, while carbon dioxide emissions are also 20-30 per cent lower. The use of Wärtsilä’s duel-fuel engine technology will enable this ferry to sail without restrictions in Sulphur Emission Control Areas (SECAs) and Nitrogen Emission Control Areas (NECAs). LNG offers the most economical and environmentally sound solution for the future.
