It is all about emission per ton cargo per distance
• Improve efficiency (reduce losses)• Improve existing technologies
• Propulsion and rudder efficiency• Hull efficiency• Combustion improvements
• Combine existing technologies in new ways• Combining propellers and rudders with DE systems• NEW Combine equipment and ship design
• Develop new technologies • LLC – electrical propulsion system• DF – engines• Waste heat recovery systems
• Reduce emissions• Primary methods
– New fuel types• Gas, Dual Fuel solutions, LSHFO, Bio-fuel, others
– Change combustion parameters• Wet methods
• Secondary methods• Scrubbers (reducing Sox) • SCR’s (reducing NOx)
