CEMS
FTIR-Based Continuous Emission Monitoring System for Modern Marine Operations
i-CEMS is an FTIR-based Continuous Emission Monitoring System designed for modern marine operations. It continuously measures, records, and reports exhaust emissions in real time, supporting regulatory compliance, accurate emission data, lower maintenance, and reduced operational costs through automated monitoring.
The system provides tamper-proof, class-approved data logs that satisfy flag state and port state control requirements, and integrates with the vessel's existing data management platform for remote data access and automated regulatory reporting.

A Continuous Emission Monitoring System (CEMS) for ships is an automated, real-time system that continuously measures, records, and reports exhaust gas emissions from a vessel's main and auxiliary engines. Integri Marine's i-CEMS uses FTIR (Fourier Transform Infrared) spectroscopy and complementary analyser technologies to measure SO₂, NOₓ, CO, CO₂, O₂, and Particulate Matter simultaneously, supporting compliance with IMO DCS, EU MRV, and MARPOL Annex VI reporting requirements.
The i-CEMS simultaneously measures: Sulphur Dioxide (SO₂), Nitrogen Oxides (NOₓ = NO + NO₂), Carbon Monoxide (CO), Carbon Dioxide (CO₂), Oxygen (O₂), and Total Particulate Matter (PM). These cover all parameters required for EU MRV, IMO DCS, MARPOL Annex VI, and national emission reporting frameworks.
i-CEMS automatically generates emission reports formatted for IMO Data Collection System (DCS) and EU Monitoring, Reporting and Verification (MRV) submissions. The system's tamper-proof, 21 CFR Part 11 compliant data logger provides an auditable, time-stamped record of all emission measurements that satisfies flag state and port state control requirements without manual data entry or estimation.
Yes. i-CEMS integrates washwater quality sensors — including pH, PAH (Polycyclic Aromatic Hydrocarbons), and turbidity monitors — to verify that the scrubber's washwater discharge meets the IMO MEPC.259(68) limits. This combined stack gas and washwater monitoring capability provides a complete closed-loop scrubber compliance solution.
