Compliance & Regulations
Ensure documented compliance with IMO MARPOL Annex VI
Operating in international waters requires documented control of exhaust gas emissions. With tightening environmental regulations and increasing inspections, reliable emission monitoring is essential for vessels equipped with exhaust gas cleaning systems.
ShipCEMS is designed to support continuous compliance with IMO MARPOL Annex VI by delivering accurate and traceable measurement of exhaust gas emissions.

Understanding MARPOL Annex VI requirements
MARPOL Annex VI regulates air pollution from ships and sets limits on sulphur oxide emissions. For vessels operating with scrubbers, compliance is verified by monitoring the ratio between sulphur dioxide (SO₂) and carbon dioxide (CO₂) in the exhaust gas.
Instead of measuring fuel sulphur content directly, authorities require documentation that the SO₂/CO₂ ratio remains within permitted limits.
This means you must:
- Continuously measure SO₂ and CO₂
- Calculate the emission ratio
- Store and document measurement data
- Provide records during inspections
ShipCEMS delivers this documentation automatically.
Compliance in Emission Control Areas – ECAs
In designated Emission Control Areas, stricter sulphur limits apply. Port state control authorities may request documentation proving that the vessel operates within the allowed emission levels.
With continuous monitoring and data logging, you can:
- Demonstrate compliance during ECA operation
- Provide historical emission data upon request
- Reduce the risk of penalties or delays
- Operate with confidence in high-regulation waters
Reliable data reduces uncertainty during inspections.
Continuous monitoring – not periodic checks
Regulatory authorities expect continuous emission verification for scrubber-equipped vessels. Manual sampling or periodic checks are not sufficient to demonstrate ongoing compliance.
ShipCEMS is designed for:
- Continuous measurement during operation
- Automatic ratio calculation
- Alarm handling when thresholds are exceeded
- Secure data storage
This ensures that compliance is maintained – not only documented after the fact.
Documentation ready for inspection
During port inspections or flag state audits, documentation must be accessible and traceable.
ShipCEMS supports:
- Continuous data logging
- Time-stamped emission records
- Export functionality
- Integration with vessel reporting systems
You get transparent documentation that supports inspection procedures and simplifies regulatory reporting.
Supporting scrubber performance verification
Emission monitoring is not only about compliance. It also provides insight into scrubber performance.
By continuously monitoring emission levels, you can:
- Verify scrubber efficiency
- Detect deviations early
- Support maintenance planning
- Document operational performance
This strengthens both environmental compliance and operational reliability.
Prepared for evolving marine regulations
Environmental regulations continue to evolve. Stricter requirements, new reporting frameworks and additional emission parameters may be introduced over time.
ShipCEMS is built on flexible measurement technology, allowing adaptation to:
- Additional gas parameters
- Extended reporting requirements
- Integration with digital fleet systems
This future-proofs your emission monitoring strategy.
Compliance supported by marine expertise
Regulatory compliance is not only about equipment – it requires correct installation, configuration and commissioning.
Norsk Analyse supports you with:
- System configuration according to vessel type
- Installation guidance for marine environments
- Commissioning and validation
- Ongoing service and calibration support
You gain a partner who understands both emission measurement technology and marine operational requirements.
