  1. 5.3 Fuel Switching Tripartite, Tokyo, 15th & 16th October 2010

  2. 5.3 Fuel Switching - The need to change between Fuels • IMO Requirements • North European SECA (Main Engine and Auxiliaries including boilers) • North American ECA (Main Engine and Auxiliaries including boilers) • Puerto Rico ECA (Main Engine and Auxiliaries including boilers) • Regional Legislation • EU Sulphur Directive (0.1% Sulphur at Berth) (Auxiliary Engines and Boilers) • California Air Resource Board (Main Engine and Auxiliaries excluding boilers)

  3. 5.3 Fuel Switching - Challenges • Storage and Segregation of multiple fuel types • Vessels traditionally designed for 1 fuel type. • Transfer lines/equipment. (source of contamination) • Bunkering lines. (source of cross contamination) • Daily Use Tanks. (two or more) • System & Cylinder Oil (Lower TBN) • Switching Activity • Time to change, duplication of pipelines and equipment. • Cross Contamination. • Manual Changeover/Automatic Changeover.

  4. 5.3 Fuel Switching - Challenges • Technical Issues • Low viscosity • Manufacturer’s Recommendations (Class Requirement) • Reduced lubricity • Increased wear • Manufacturer’s Recommendations • Temperature Changes • Thermal Shock of equipment • Pipeline flanges loosening • Safety Issues • Using distillate fuel in Boilers • Flame eye’s • Purge time • Duplication of pipe work/burner
