company Unifeeder has been operating the world's first LNG powered container vessel, the Wes Amelie, since late 2017, transiting between the port of Rotterdam and the Baltics on a weekly schedule. Container shipping company Maersk Group has decided to introduce LNG-powered container ships. The DEME Group has contracted Wärtsilä to power its new generation ‘Antigoon’ class dredger with dual fuel (DF) engines. Crowley Maritime of Jacksonville, Florida, launched two LNG-powered ConRo ships, the Coquí and Taino, in 2018 and 2019, respectively. In 2014, Shell ordered a dedicated LNG bunker vessel. It is planned to go into service in Rotterdam in the summer of 2017 The International Convention for the Prevention of Pollution from Ships (MARPOL), adopted by the IMO, has mandated that marine vessels shall not consume fuel (bunker fuel, diesel, etc.) with a sulphur content greater than 0.5% from the year 2020 within international waters and the coastal areas of countries adopting the same regulation. Replacement of high sulphur bunker fuel with sulphur-free LNG is required on a major scale in the marine transport sector, as low sulphur liquid fuels are costlier than LNG. Japan's is planning to use LNG as bunker fuel by 2020. BHP, one of the largest mining companies in the world, is aiming to commission minerals transport ships powered with LNG by late 2021. In January 2021, 175 sea-going LNG-powered ships were in service, with another 200 ships ordered. Use of LNG on rail Florida East Coast Railway has 24 GE ES44C4 locomotives adapted to run on LNG fuel. Trade The global trade in LNG is growing rapidly from negligible in 1970 to what is expected to be a globally substantial amount by 2020. As a reference, the 2014 global production of crude oil was per day or per year. In 1970, global LNG trade was of 3 billion cubic metres (bcm) (0.11 quads). In 2011, it was 331 bcm (11.92 quads). The U.S. started exporting LNG in February 2016. The Black & Veatch Oct 2014 forecast is that by 2020, the U.S. alone will export between or by heating value . E&Y projects global LNG demand could hit 400 mtpa (19.7 quads) by 2020. If that occurs, the LNG market will be roughly 10% the size of the global crude oil market, and that does not count the vast majority of natural gas which is delivered via pipeline directly from the well to the
