Petite Powerhouse
Technologically speaking, the Wärtsilä 14 comes in 12- and 16-cylinder configurations, with a power output between 755 and 1340 kWm in mechanical propulsion and 675 – 1155 kWe in an auxiliary generation and diesel-electric propulsion.
The engine is lighter and more compact compared to others in the market. So, it saves space and weight in the ship. It’s load taking capability is much better compared to medium-speed engines, so it has a fast-start and performs better in harsh environments. It is also equipped with the Wärtsilä UNIC automation system modules for monitoring and improved safety.
“There is a huge business potential for such an engine in this power range,” says Klemola. “If you visit a harbour you might see many ships working around the piers that would be perfect for the Wärtsilä 14, such as tugs, fishing boats or smaller sea-going vessels. The engine also fits auxiliary power generation requirements for merchant ships like container carriers or tankers.
The Wärtsilä 14 fits those applications which require small high-speed engines: smaller vessels using cleaner fuels on the lower end of the power range, such as the new Wärtsilä HY Tug 40. The shallow-draft tug includes two Wärtsilä 14 engines and a hybrid propulsion system which delivers flexible operating modes, such as one for zero emissions.
“The Wärtsilä HY Tug 40 is really a fantastic showcase for us,” explains Kaarniemi. “We designed the entire ship and propulsion system.”
