Since the beginning of the year in the SECA emission control areas of Europe, only residual fuels with a maximum sulfur content of one per cent is permitted. On the West Coast of the United States a similar ban has been in force since July 1, 2009. The application of the new regulations is not without hazards. A higher number of propulsion failures directly associated with switching over from one fuel to another have been reported. Due to fuel temperature considerations, the changeover from one fuel to the other is not immediate but must be a gradually spread out over a period that can easily last from 30 to 60 minutes. Failure to do this gradually, could lead to seizure of the fuel pump due to low viscosity of the diesel fuel and thermal shock. This delay needs to be taken into account in the ship’s navigational planning of arrival or departure to ensure an orderly fuel change-over prior to entering the ECA. During changeover there is a danger of sludge formation, clogged fuel filters and separators, sticking fuel injection pumps and plugged fuel nozzles. Longer term effects if using a lubrication oil that is not matched to the fuel in use, can lead to cylinder liner lacquering on four-stroke engines with prolonged operation on low sulfur (mainly distillate) fuels causing expensive repair bills! Let’s hope that lessons are learned from the experience of others and these problems are avoided.
