25+ years of professional experience

Our expertise

Ecoxys professional environment combines deep technical expertise with practical field experience. Our discipline leader for emission measurements has over 25 years of experience in engine systems and emission outputs – from marine diesel engines to gas turbines.

Deep professional grounding

Ecoxys discipline leader for emission measurements has worked on issues related to emission outputs from both vehicle engines and marine diesel engines for over 25 years. For two decades at the Marine Technical Center in Trondheim (NTH/NTNU and Marintek), projects funded by marine diesel manufacturers, StatoilHydro, the Research Council of Norway, shipping associations, and environmental authorities were carried out.

This background gives Ecoxy a technical depth of understanding that is rare in the industry and ensures that our measurements and analyses are professionally sound.

Field engineer program

All Ecoxy field engineers undergo an internal qualification program that ensures they possess the competence required for accredited measurements. The program covers:

Theory and practice of exhaust measurement according to ISO 8178-2 and IMO NOx Technical Code

Operation and maintenance of Horiba PG-250 and other measuring equipment

Safety training for work offshore and on board vessels

Report writing and documentation according to accreditation requirements

Field practice under the guidance of experienced engineers

Methodology for NOx calculation

Ecoxy assists shipping companies and operators in establishing the correct calculation basis for NOx emissions:

Actual vs. ISO 8178 load profile: Ecoxy assesses whether it is more accurate to use the actual operating profile instead of the standard ISO profile to calculate the NOx factor.

Measurement at four load points: 100%, 75%, 50%, and 25% load for main engines. Simplified requirements at 50% for auxiliary engines.

Source-specific emission factors: Establishment of emission factors for each individual emission point for increased precision in NOx reporting.
