Houston – “Domestic ships in North America have three options to meet new emissions control regulations; install scrubbers, burn low sulphur fuel or switch to LNG fuel for the ship’s propulsion,” says Kenneth Vareide, director of operations for DNV North America Maritime. DNV’s new report, Greener shipping in North America, proposes that LNG l is the most efficicient and economical way to meet air emissions requirements in the US and Canada that take effect in August 2012.
Environmental Control Areas (ECA) will gradually be enforced along the North American coastlines. They will have full force in 2015 and 2016, leaving shipowners a limited number of options for modifications to their ships if they want to continue trade in North America. Says Kenneth Vareide, “A LNG fuelled propulsion plant may add about $3.6 million to the cost of a typical domestic cargoship, however, over the operating life of the vessel, at today’s gas rates, LNG fuel would save more than $4 million over scrubbers and $12 million for low sulphur fuel.” Specifically, the use of LNG fuel for a ship would reduce nitrous oxide (NOx) emissions by 85-90%, sulphur dioxide (SO2) and particulate matter by almost 100%, and it would result in 15-20% less greenhouse gas emissions.
