Results of an extensive atmospheric research project carried out in 2010 have now proved California’s clean-fuel regulations (applied within 24 miles of the coast since July 2009) have been effective in reducing Sulphur Dioxide air pollution from ships. In a recent press release,  Chairman of California Air Resources Board, Mary D. Nichols declared this as good news for California, and for the nation.  But there is a downside to that good news; the procedure of fuel-switching from heavy fuel (HFO) to low-sulfur distillate fuel oil (LSDFO) carries a risk of engine shutdown or malfunction, and the frequency of these incidents is on the increase.Spearheaded by scientists aboard NOAA research ship Atlantis the composition of emissions from more than 70 ships over 24 days was analysed during the ARB federal-state research project, and within that timeframe researchers also found that all ships were burning low-sulfur fuel. Assuredly, for economy, the majority had switched fu... [More]
