LNG is becoming more and more attractive as a marine fuel

As climbing fuel prices and increasingly stringent environmental regulations set in, Wärtsilä is seeing “considerable gas conversion potential” in the marine industry.

In order to maximise fuel efficiency and minimise emissions, conversions of existing engines to gas operation are becoming more and more popular.

Just as with the power sector, the marine industry is becoming increasingly interested in liquid natural gas (LNG) as a marine fuel to help it comply with the new environmental regulations.

Markus Ljungkvist, director, business development, projects, Wärtsilä, said: “Engine technology is the same in power plants and vessels. However, there are marine classification rules and regulations as well as ship design related matters that need to be considered in terms of gas conversion in marine vessels.”

“An LNG tank needs to be fitted inside the vessel or mounted on the deck, whereas a power plant can be connected to a gas pipeline,” he added.  

The most pressing issues at the moment are those relating to operating within Emission Control Areas (ECAs) that come into effect in 2015.
