Power solutions provider Wärtsilä has introduced a more powerful version for marine applications of its Wärtsilä 32 engine. First introduced in the 1980s, the Wärtsilä 32 engine is used by both the marine and land-based power plants markets.
In the marine industry the engine is used for both main engine and auxiliary engine applications. It is typically selected to power different types of tankers, container vessels, and offshore support and drilling vessels and in the cruise and ferry sector. In auxiliary electric production, the Wärtsilä 32 is widely utilized in all vessel categories where high auxiliary load is needed.
The new and upgraded version is available with an increased power output of 580 kW per cylinder at 750 RPM (50 Hz version). This represents a 15 percent increase in power output over the earlier 32 engine, despite having the same external dimensions.
This increased output means that the Wärtsilä 32 now covers a power range from 3 MW to 9.3 MW. One area where this new power output is expected to be embraced is in the offshore drillship market, where its compact design and Wärtsilä’s Low Loss Concept will offer a package for diesel electric propulsion.
The engine is able to operate efficiently and economically on low sulphur fuels (<0.1% S), making it suitable for operation in emission-controlled areas. It can also be equipped with a SCR catalyst, such as the Wärtsilä NOR (nitrogen oxide reducer), which can reduce NOx emissions by as much as 95 percent. The machinery is IMO Tier III compliant and the standard Wärtsilä 32 fulfils IMO Tier II regulations. Juhani Hupli, Vice President, Ship Power Technology, Wärtsilä Ship Power, said: "Wärtsilä is constantly seeking to improve and further develop its engine portfolio. These solutions enable them to meet the challenges posed by rising fuel and operating costs, and increasingly stringent environmental legislation."
