Recently, Liquefied Natural Gas (LNG) use has been increasing, while the number of new consumers has also risen. LNG is one means for the distribution of Natural Gas, and the feature of Natural Gas is that it can be a clean energy source among natural resources, such as oil and gas which are extracted underground. Recently, vast extractable deposits have been found around the world, including the so‐called "shale gas". LNG has several advantages in consideration of the entire energy supply chain, such as higher transportation efficiency, and a well‐organized distribution infrastructure, supported by mature industries and their markets. Particularly, in marine applications, floating infrastructure, Floating LNG production (FLNG) or Floating storage and regasification unit (FSRU), is presenting many business opportunities to those who can set up facilities in the short term, and at a competitive initial cost; moreover, it can help those who want to be free from geopolitical risk. Also in the marine fuel sector, LNG might be the best possible solution in regard to environmental issues, by replacing marine heavy oil, while saving on total costs. MHI is currently addressing activities to contribute to LNG market expansion to the marine industry, "MHI‐GEMS" as we call it, which is representing our business serving onboard LNG equipment and its integration into the whole system design to shipbuilders worldwide.
