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.
The Protea 2000 emissions monitoring system is approved for the analysis of exhaust gases from the engines and boilers of ships and offshore rigs. Robust and with proven reliability, up to six gases can be measured including SO2, CO2 and NOx.
The Protea 2000 emissions monitoring system comprises up to 6 exhaust mounted analysers, each with automatic verification facilities. Emissions data from the entire system is securely managed and displayed at a dedicated Classification Society approved panel PC, with outputs to networks, control systems, and reporting facilities.
The advanced Protea 2000 analyser utilises an in-situ (inside the exhaust) sample cell so avoiding the need to extract gas. Importantly this avoids the use of costly, high maintenance sample handling systems, and enables analysis of an unmodified, truly representative gas sample.
Exhaust gases from the combustion of residual and distillate fuels can be analysed, so that compliance can be confirmed in port, in Emissions Control Areas and in international waters. The Protea 2000 includes highly effective sintered filters that prevent the ingress of particulate matter into the sample gas cell and a heater to prevent condensation and deposits where the exhaust is below its dew point. Construction materials are ideally suited to the marine environment.
The measurement range of Protea 2000 analysers is such that compliance can be confirmed even when regulated emissions are at a very low level. Emissions after an exhaust gas scrubber, that are the equivalent of 0.1% sulphur fuel, are readily measured. Protea 2000 analyser solutions can be fitted to all sizes of exhaust and ATEX/IEC approved options are available for use in the hazardous areas typically found offshore.
