2015 North American ECA: Lessons Learned in CA

摘要

California experienced a 300% increase in loss of propulsion (LOP) incidents since its distillate fuel regulationrncame into effect in 2009. The compression ignition (Diesel) engines aboard modern cargo ships over 10,000 grossrntons use 3.0% sulfur Heavy Fuel Oil (HFO). This fuel must be heated to flow through the fuel lines because atrnnormal ambient temperature HFO has the consistency of tar. Distillate fuel in contrast does not require the highrntemperatures, and the thermodynamics of cooling metal, gaskets and seals resulted in leaks, along with filterrnclogging from engine buildup scrubbing. In addition, the cost savings of using HFO are significant over the use ofrndistillate fuel which is typically around US$300 more per ton.
