ONBOARD EMISSION MEASUREMENT

NOx Spot Check

Main engine and generator measurements to assess SCR performance and catalyst condition.

From measurement
to maintenance.

Regular onboard measurements help track NOx reduction performance and identify when the SCR system needs closer inspection.

Measurement
Record operating conditions and measured NOx reduction performance.
Condition review
Review catalyst performance trends, urea dosing and SCR operating condition.
Follow-up
Recommend inspection, dosing adjustment or catalyst replacement assessment where needed.

MEASUREMENT IN PRACTICE

SCR performance and catalyst condition

NOx measurement equipment installed onboard, from the company introduction — Onboard measurement equipment

SCR de-NOx performance example at 100 percent load: measured NOx decreases from 1106 to 86 ppm with increasing urea consumption — Example at 100% load from the company introduction. Results depend on the vessel and test conditions.
