While marine engines capable of utilising LNG as a fuel have been used in the LNG carrier industry for decades, the first non-LNG carrier vessel - the LNG-fuelled ferry GLUTRA with gas engines and storage - came into service in 2000, in Norway. As of December 2016 there were 97 LNG-fuelled ships in operation, mostly smaller vessels such as ferries, operating extensively in the ECAs of north west Europe and North America.
As of December 2016 there were 91 LNG-fuelled ships on order. There were also approximately another 70 LNG-ready ships either in service or on order.
There were also approximately another 70 LNG-ready ships either in service or on order. These vessels are designed for a streamlined conversion from conventional fuels to LNG when the time is deemed right. The existing order book is showing a growing number of deep-sea vessels including cruise ships, container vessels and bulk carriers being built to LNG dual-fuel standards.
The world’s first dual-fuelled container vessels entered service in late 2015 for TOTE Maritime in the trade between the U.S. and Puerto Rico. Since their introduction they have been running on LNG for a vast majority of their operating hours. These vessels again prove that the technology works safely and effectively.
