RN EVALUATES SCR VIABILITY FOR FRIGATE GENSETS

The UK Royal Navy has conducted a major shore-based Selective Catalytic Reduction (SCR) trial which is part of an ongoing exhaust emission control programme aimed at ensuring the Royal Navy is ready to meet a wide range of marine air emissions legislative scenarios. The most important part of the work has been the recent and very successful Type 23 frigate-based full scale SCR 'demonstrator' trial. A urea type compact plant was designed which was capable of 90%-plus NOx reduction (as well as significant hydrocarbon and CO reduction) from the standard Paxman Valenta 12RPA200Z 1.3 MW medium-speed auxiliary diesel operating on standard NATO Navy fuel (sulphur content generally 0.2 -0.5%wt). Overall, the trial itself and the associated studies, including detailed ship tankage calculations, have shown that a commercial, compact SCR plant is a viable option for a Type 23 frigate and other similar warships, whether as a retrofit or for incorporation into newbuildings.
