With built-in upgradability and fuel flexibility, the new Wärtsilä 46TS- DF can help you to power a more sustainable future. It represents the next generation of medium-speed engines and is designed to set a new benchmark for fuel efficiency and emissions performance while offering future-fuel flexibility.
Based on experience collected from the Wärtsilä 46, 46F and 50 engine families, the Wärtsilä 46TS DF adds state-of-the-art two-stage turbocharging to deliver unprecedented levels of efficiency and power density across a wide operational range for vessels in every segment. The engine is available in six to 16-cylinder configurations, corresponding to a power output range of 7.8 to 20.8 MW at 600 rpm.
Advanced dual-fuel technology, ready for future fuels
Wärtsilä’s proven dual-fuel technology enables vessels to operate on both gas and liquid fuel, and to switch between the two according to cost, availability and local environmental regulations.
The key features:
With its intrinsically modular design, the Wärtsilä 46TS-DF allows vessel owners and operators to act now to reduce fuel consumption and emissions in the knowledge that modularity enables potential upgrades in the future, also to run on alternative fuels.
The Wärtsilä 46TS-DF is suitable for a broad range of vessel types and applications – for example as a main propulsion engine in diesel-electric, mechanical and hybrid installations. The engine can be optimised to run either at constant speed or along a propeller curve.
The solution is suitable for cruise and ferry operators that are exploring ways to minimise fuel expenses while maximising environmental performance. For merchant vessels the Wärtsilä 46TS can be used as a main engine onboard medium to large gas tankers, bulk carriers, container ships and special vessels such as dredgers.
