Scrubber (EGCS) compliance

Scrubber compliance is driven by the global limit on the sulphur content of marine fuels that the International Maritime Organization (IMO) introduced on 1 January 2020 to reduce air-polluting sulphur emissions.

Installing an Exhaust Gas Cleaning System (EGCS), commonly known as scrubbers, on a vessel is only part of the compliance pathway. True scrubber compliance depends on the ability to continuously measure, document, and demonstrate emissions performance under real operating conditions – not just at commissioning, but throughout the vessel’s entire lifecycle.

By continuously monitoring SO2 and CO2 emissions directly in the exhaust stream, vessels can reliably verify MARPOL compliance in emission control areas (ECA) according to the IMO Global Sulphur Cap 2020 under all operating conditions.

The scrubber compliance challenge

Scrubber compliance is challenging, requiring vessels to continuously demonstrate that sulphur emissions are effectively reduced under all operating conditions to meet the IMO regulations.

In practice, the harsh marine environment places significant demands on scrubber monitoring equipment, where complex maintenance routines and frequent service needs can drive up lifecycle costs and increase crew workload.

Danfoss IXA scrubber CEMS application, MES 1002, addresses these challenges by simplifying compliance through reliable, continuous SO2 and CO2 monitoring and enabling easy onboard maintenance.

This reduces operational service interventions, lowers operating costs, and ensures consistent, compliant scrubber performance under all operating conditions over time.

Avoid compliance risks with continuous emission monitoring

For vessels operating with exhaust gas cleaning systems (EGCS), regulatory compliance depends on continuous and well-documented emissions monitoring. Demonstrating compliance with sulphur limits requires uninterrupted measurement of exhaust gas parameters, ensuring that emissions remain within IMO-equivalent limits at all times.

This places strict demands on monitoring equipment: scrubber CEMS applications must operate reliably without interruption, and any deviations or system issues must be detected and addressed immediately to avoid compliance risks.
