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)
