European ferry and logistics provider DFDS and global instrumentations supplier Green Instruments have a long history of collaboration. For long, monitoring of sulfur-reducing initiatives has been the focal point, but a constant strive to be on the forefront of development has teamed up the Danish duo in new ways.

A long search for ways of monitoring particle emission in mass and numbers initiated the pilot project, currently in progress onboard ARK Dania. The project goes beyond SOx monitoring and seeks to measure the content of particles in exhaust gas, before and in immediate extension of the wet scrubber onboard the cargo ship. Using Green Instruments’ acclaimed opacity technology, originally developed to detect oil mist and monitor smoke density, the goal is to gain factual knowledge on actual particle-diminishing effects of scrubber systems. Being able to document particle emission after a scrubber is hitherto unexamined area, and while the duo anticipates particle documentation to be the future of exhaust monitoring and clean air, long-term potential of the project is foreseen.
