Award-winning engine chosen for new state-of-the-art harbour icebreaker
Already recognised by Guinness World Records as the world's most fuel-efficient four-stroke diesel engine, the Wärtsilä 31 marine engine is set to raise the bar in terms of improving ship fuel consumption and reducing emissions.
Designed for a broad range of ship types and applications - both as a main propulsion engine and in diesel electric configurations, or as an auxiliary engine - this game-changing, first of a new generation of medium speed engines is creating a new benchmark in efficiency and overall emissions performance.
Apart from offering the best fuel economy of any engine in its class the revolutionary award-winning Wärtsilä 31 features a modular design which significantly cuts maintenance time and costs, improves power availability and reduces the need for parts. This makes the engine ideally suited for anchor handling tug supply vessels, offshore support ships, drilling and semi-submersible vessels where the need for operational flexibility, high power density, long intervals between overhauls and high levels of safety are vitally important.
In the cruise and ferry sector, the record-breaking engine enables owners and operators to reduce fuel costs while maintaining high standards of environmental performance and in the merchant fleet it is suitable for main engine applications for small-to-medium tankers, bulk carriers and container vessels.
Now the pioneering marine engine has received a further high-profile accolade, winning the Marine Engines Award at this month’s European Marine Engineering Conference in Amsterdam. Judges noted that the winning entry is an "innovative and original development that demonstrates an engineering innovation that represents a step-change in engine technology".
There are three versions of the Wärtsilä 31 - diesel, dual-fuel and spark-ignited gas. Its multi-fuel capabilities extend the possibilities for operators to use different qualities of fuels, from very light to very heavy diesel, and a range of different qualities of gas. It is designed for a variety of vessel types requiring main engine propulsion in the 4.2 to 9.8 MW power range.
The first orders have already been received by the engine's Finland-based manufacturer. Wärtsilä 31 engines will be used to power a state-of-the-art new generation harbour icebreaker based on the Aker ARC 124 concept which is currently being built at the PJSC Vyborg shipyard in Russia. The vessel is being constructed on behalf of FSUE Atomflot, a subsidiary of the Russian State Corporation for Atomic Energy.
Designed specifically to tackle challenging port and harbour conditions and to operate in temperatures as low as minus 50°C, this specialist vessel will support liquefied natural gas (LNG) carriers approaching the new Sabetta seaport in the Yamal Peninsula, so that LNG can be exported throughout the year from Siberian oil and gas fields. The icebreaker's main engine will be fitted with the marine industry's most advanced two-stage turbocharging system to optimise engine and fuel efficiency, operational flexibility and high power performance.

According to Wärtsilä, its innovative, award-winning modular engine provides vital marine business benefits, including:
• improved operational availability
• increased service efficiency
• easy to convert
• increased efficiency in planning and maintenance work.
"The Wärtsilä 31 truly represents a breakthrough in marine engine efficiency and its introduction marked the setting of a new benchmark for four-stroke engines," says Stefan Wiik, vice president, Engines, Wärtsilä Marine Solutions.
"It provides customers with the marine industry’s most advanced, powerful, fuel efficient, fuel flexible and environmentally sound engine. The engine’s development has been based on the very latest technology and it opens the door to a new level of optimisation that is valid throughout the entire life of the vessel."
