Reasons to Consider LNG Conversions• LNG cargo carriers use cargo burn-off for fuel (steam, then diesel)approaching 240 vessels; over 40 years experience(classification by ABS, DNV, others)• Beginning in 2000 with the ferry Glutra, first non-LNG cargo vesselthese LNG vessels, mostly in Norway (DNV), now approaching 30• Recent conversion of a 5 year old 25,000 DWT producttanker Bit Viking from HFO to LNG in atwo month conversion (DNV)• Harvey Gulf International contracted for4 LNG powered offshore supply vessels(first US flag, ABS, U.S. Coast Guard) 9LNG Fuel ConversionsGLMRI Affiliates 2/27/12
