Emissions & Monitoring

About SMS and Protea

Protea’s goal is the development and introduction of new technologies for the online measurement of gases in industrial, research and maritime applications, to help control process and reduce environmental emissions. SMS supplies, installs, and supports technology solutions that monitor a ship’s compliance with an increasingly complex set of maritime emissions regulations and improve performance of the ship and its systems. Working closely together enables the organisations to jointly provide ship operators with a first-class service based on a wealth of experience and expertise.

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 have been sulphur oxides – SOx, and nitrogen oxides – NOx. While these are still of great relevance the focus is now firmly on Greenhouse Gases. The ongoing creation of Emission Control Areas and stringent limits on fuel sulphur content in port coupled with local regulation restricting scrubber use are challenging 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.

Marine Scrubber Monitoring and Control

Protea’s P2000 marine emissions analyser plays an integral role in the monitoring and operation of Exhaust Gas Cleaning Systems that are widely used by ships to control sulphur oxide emissions. There are now some 6000 ships fitted with these systems known as scrubbers.

The Protea P2000 provides continuous monitoring and recording of SO2 and CO2 emissions in line with the latest IMO Exhaust Gas Cleaning System Guidelines (MEPC.340(77)), so giving ship operators the peace of mind that emissions are in compliance with MARPOL Annex VI regulations 4 & 14 wherever their vessels are trading.

EGCS manufacturers work closely with Protea integrating outputs from the P2000 for system management and optimization of scrubbing efficiency.  The P2000 also assists ship operators when entering or leaving Emission Control Areas as the continuous real time display provides confirmation of emissions compliance when the ship switches fuels at the most cost-effective time.
