Wärtsilä’s scope of supply for this contract includes 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. The propellers are designed with the lowest possible pressure impulses for superb vibration control.
The vessel will be fueled by LNG, meaning that sulphur oxide emissions will be almost zero, and nitrogen oxide emissions will be at least 80 percent below the International Maritime Organization’s (IMO) current stipulated level. Furthermore, there is a reduction of particulate emissions of more than 90 percent compared to the emissions from conventional diesel engines, while carbon dioxide emissions are also 20-30 percent 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.
“One of the top priorities at Viking Line is to lower the emissions and fuel consumption on our fleet . We were looking for a good monitoring tool that automatically regulated power consumption and was as easy to operate as a traffic light as a result ABB’s EMMA became our first choice,” said Kari Granberg, Project Manager at Viking Line Abp.
