The document presents Wärtsilä's strategies and innovations in fuel gas handling systems, particularly focusing on liquefied natural gas (LNG) for marine applications. It highlights the growth of the LNG chain, the design challenges of gas-fueled engines, and different tank designs for storing LNG. The presentation also outlines the successful deployment of Wärtsilä's LNGPact systems across various vessel types and the expected trends in the industry.

You better store it in a very well
insulated thermos bottle!
