Specialists in design, manufacture and supply of integrated Continuous Emission Monitoring and Process Analyser systems for all types of industrial application. Protea utilises its own unique advanced technologies to meet customer requirements.


PROTEA LTD provide a solution to Marine Emissions.

The need to demonstrate environmental responsibility is key for today’s marine and offshore industries. Charterers and the public demand high standards of performance and reliability. Fuels and exhaust gas emissions are also the subject of international, regional and national controls. The most significant is IMO MARPOL Annex VI – Regulations for the Prevention of Air Pollution from Ships, which also applies to mobile offshore drilling units and other oil industry platforms.

The most important gases in terms of emissions are currently sulphur oxides – SOx, and nitrogen oxides – NOx. Annex VI has a schedule for significant reductions in both over the next 10 years. The creation of Emission Control Areas and stringent limits on fuel sulphur content in port are challenging particularly for the shipping industry and its suppliers. Ship operators have near imminent decisions to make based on a complex set of circumstances and a fluid regulatory background. The penalties for non-compliance are potentially huge. Whilst the pace of change has created uncertainty and appears to have pushed the boundaries for some technologies, the Protea 2000 emissions monitoring system has been proven in long-term service onboard ship as a robust and reliable method of confirming compliance with emissions regulations.

Direct in-situ measurement

  • One analyser measures multiple gases
  • No requirement for extractive sample handling systems
  • Auto-verification facilities
  • Measurement of exhaust from residual and distillate fuel combustion
  • High sensitivity at low levels
  • User friendly display and secure recording of data from up to 6 analysers
  • Multiple data outputs

Protea’s Marine Emissions Analysers

Protea 2000 In-Situ Infra-red gas analyser connected to a Protea Control Unit forms the basis of a Continuous Emission Monitoring System (CEMS).
