    Wärtsilä launches the Wärtsilä 31SG pure gas engine for marine market applications

    The technology group Wärtsilä launches the Wärtsilä 31SG pure gas engine for marine market applications, the company said in its release. It is based on the successful Wärtsilä 31 product platform. The diesel version of the engine has been recognised by Guinness World Records as being the world’s most efficient 4-stroke diesel engine. The Wärtsilä 31SG engine further reduces the total cost of ownership and the environmental footprint for vessels operating in regions where there is a developed gas infrastructure. The commercial launch of the Wärtsilä 31SG takes place in September at the Gastech 2019 conference and exhibition being held in Houston, Texas, as well as at the Neva St. Petersburg exhibition and maritime forum in St.Petersburg, Russia.

    Following Wärtsilä’s introduction of dual-fuel engine technology in the 1990s, LNG has become established as a viable and attractive marine fuel. This has led to the rapid expansion of the global LNG bunkering infrastructure, which sets the stage for the next evolutionary step, namely a larger scale application of pure gas engines within the marine and offshore industries.

    “The highly efficient Wärtsilä 31SG moves the industry forward by providing owners and operators with a practical means for lowering costs and enhancing environmental sustainability. The gas-only focus and lean-burn spark ignition technology allows for further optimisation of thermal efficiency, while lowering greenhouse gas emissions and facilitating adaptations for alternative heavier gas fuels, such as LPG,” says Rasmus Teir, Product Manager, Wärtsilä Marine.

    Wärtsilä has an extensive track record with SG lean-burn technology, with more than 1800 engines delivered and 37 million running hours accumulated in demanding land-based energy market applications. The Wärtsilä 31SG was introduced to the energy market in 2017, and now builds on this pedigree to offer reliable pure gas solutions with low lifecycle costs also for marine customers.

    The increasing adoption of hybrid propulsion offers additional opportunities for pure gas engines. The Wärtsilä 31SG is ideally suited for hybrid applications, since it provides outstanding thermal efficiency while also providing investment cost reductions that help offset the additional cost of energy storage. Pairing the Wärtsilä 31SG with battery packs furthermore enables designing for redundancy, while securing the highest total system efficiency.

    This latest Wärtsilä development is in line with the company’s target for reducing the greenhouse gas emissions from gas engines by 15 percent from 2015 levels by 2020.

    Wärtsilä in brief:

    Wärtsilä is a global leader in smart technologies and complete lifecycle solutions for the marine and energy markets. By emphasising sustainable innovation, total efficiency and data analytics, Wärtsilä maximises the environmental and economic performance of the vessels and power plants of its customers. In 2018, Wärtsilä’s net sales totalled EUR 5.2 billion with approximately 19,000 employees. The company has operations in over 200 locations in more than 80 countries around the world. Wärtsilä is listed on Nasdaq Helsinki.
