 Workpackage 6: Emission reduction methods (internal-water)
 

AIM: to investigate the optimal water-addition method regarding efficiency, emissions trade-off, reliability, design complexity and the safe operation on-board ships .

Objectives:

  • To confirm the NOx-reducing potential observed in lab tests
  • To model and simulate water injection processes
  • To develop water injection systems
  • To test the developed systems on-board

The Workpackage consists of two Tasks:

Task 6.1: Water Injection Techniques

Task 6.2: Humidification methods
