Reliable exhaust gas measurement – from stack to analyser
Marine exhaust gas contains moisture, soot and reactive components. To ensure accurate measurement, ShipCEMS uses a fully heated sample handling system.
The system architecture includes:
- Heated sample probe installed in the exhaust duct
- Heated sample line to prevent condensation
- Marine-grade sample conditioning unit
- Central analyser cabinet
- Automatic stream switching for multiple exhaust lines
- Integrated calibration gas functionality
By maintaining temperature throughout the sampling process, the system ensures that the gas composition reaching the analyser reflects the true exhaust conditions.
Industry-standard infrared measurement principle
ShipCEMS is based on proven non-dispersive infrared (NDIR) measurement technology – widely used for continuous gas monitoring in demanding applications.
The system enables accurate measurement of:
- SO₂
- CO₂
- SO₂/CO₂ ratio
- NOx – optional
- O₂ – optional
- Other gases on request
The measurement principle ensures stable long-term performance with minimal drift when properly maintained and calibrated.
One analyser – multiple exhaust lines
For vessels with multiple exhaust stacks or combustion processes, ShipCEMS can monitor several sampling points using a single analyser cabinet.
This design offers:
- Reduced installation footprint
- Lower equipment cost
- Simplified maintenance
- Automatic stream switching
- Centralized data logging
Only one analyser cabinet is required, while sample conditioning systems are installed per exhaust line.
Designed for safe and robust marine installation
All components are selected and configured for operation in marine engine room environments.
The system supports:
- Indoor installation with IP44 protection
- Outdoor installation with IP55 protection
- 230 / 110 VAC power supply
- Digital communication outputs
- Optional Modbus or Profibus integration
Compact cabinet design allows flexible placement onboard.
Integrated data handling and system control
The analyser cabinet manages:
- Measurement and ratio calculation
- Automatic stream switching
- Alarm handling
- Calibration routines
- Data logging and export
The system can be integrated with vessel automation systems, enabling central monitoring from the control room.
Built as a complete system – not just an analyser
ShipCEMS is delivered as a fully integrated solution. Norsk Analyse designs, configures and commissions the complete system to match your vessel layout and compliance requirements.
You do not only receive measurement hardware – you receive a marine-ready monitoring system engineered for reliable operation at sea.
