The Wärtsilä 31SG is available in 8 to 16 cylinder configurations and has a power output ranging from 4.2 to 8.8 MW, at 720 and 750 rpm. The launch of the Wärtsilä 31SG 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 a significant reduction in maintenance time and costs, thereby improving power availability and reducing the need for spare parts.
The Wärtsilä 31SG retains its high efficiency and environmental values throughout the entire lifecycle of the vessel.
The Wärtsilä 31 is designed to be suitable for a broad range of ship types and applications, in diesel electric configurations, or as an auxiliary engine. Wärtsilä 31 is a perfect solution for FSRU, LNG carrier´s, ferries and other vessel segments where operational flexibility, high power density, long intervals between overhauls, and high levels of safety are of paramount importance.
