The bulk LNG transportation industry, where LNG is commonly used as a fuel for the transporting vessel, has an excellent safety record. Over the past 50 years, more than 77,000 commercial LNG cargoes have been safely delivered and global LNG shipments have covered more than 100 million miles – about 4,000 times around the earth – without any major safety incidents in port or at sea. This is testament to the LNG industry’s rigorous design guidelines for both ships and shore facilities, as well as high standards of training and operational procedures.
The use of LNG as a marine fuel outside the LNG carrier business is a relatively new technology, as are gas only and dual-fuelled engines. However, since its introduction as a marine fuel at the turn of the century, LNG-fuelled vessels and associated bunkering operations have had an exemplary safety record. For example, the Viking Grace cruise ferry has bunkered, without incident, more than 1,000 times in Stockholm since its entry into service in 2012.
