Catalogue excerpts

Wärtsilä 31 Wärtsilä 31 is recognised by Guinness World Records as the world's most efficient 4-stroke diesel engine The Wärtsilä 31 is the first in a new generation of medium speed engines, designed to set a benchmark in efficiency and overall emissions performance.    The Wärtsilä 31 is available in 8 to 16 cylinder configurations and has a power output ranging from 4.2 to 9.8 MW, at 720 and 750 rpm. The launch of the Wärtsilä 31 introduces a 4-stroke engine having the best fuel economy of any engine in its class. At the same time, it maintains outstanding performance across the complete operating range. Its modular design enables significant reductions in maintenance time and costs, thereby improving power availability and reducing the need for spare parts. The Wärtsilä 31 retains its high efficiency and environmental values throughout the entire lifecycle of the vessel. zz Lowest fuel consumption over a wide operating range. zz Highest cylinder power in its segment, 610 kW/cylinder. zz Available in Diesel, Dual Fuel (DF) and Pure Gas (SG) versions. zz Meets the coming IMO Tier 3 regulations when operating on gas, and with an SCR when using diesel fuel. The SCR has a minimal effect on fuel consumption. zz Reliability guaranteed through extensive validation and Wärtsilä’s vast manufacturing experience. zz Supported by Wärtsilä’s extensive global service network. Typical applications The Wärtsilä 31 is designed to be suitable for a broad range of ship types and applications, both as a main propulsion engine, in dieselelectric configurations, or as an auxiliary engine. It can be optimised for running either at constant speed or along a propeller curve. In the Offshore sector, the Wärtsilä 31 is a perfect solution for OSV´s and drilling or semi-submersible vessels, where operational flexibility, high power density, long intervals between overhauls, and high levels of safety a

For the power plant market, the Wärtsilä 31 is also available in a 20V cylinder configuration. A pure gas, spark ignited (SG) version is also offered. In the cruise and ferry sector, the Wärtsilä 31 represents a particularly good investment for ferry and Ro-Pax fleet operators focusing on trimming their fuel expenses while maintaining high standards in environmental performance. Within the merchant fleet, the Wärtsilä 31 is designed for application as a main engine for small to medium sized tankers, bulk carriers, and container vessels. Operational features The modular structure of the Wärtsilä...

The new car and passenger ferry being built for Danish operator Mols-Linien, will be powered by two 8-cylinder Wärtsilä 31 main engines. “The selection of this particular engine was based on the unique efficiency for the required output, and also the favourable maintenance intervals it allows," says Flemming Kristensen, Technical Director, Mols-Linien A/S. Wärtsilä’s propulsion solution provides the efficiency and environmental sustainability needed for the new purse seiner/trawler being built by Danish shipbuilder Karstensen Shipyard. Wärtsilä’s scope includes the Wärtsilä 31 engine which has...
