Measurement report - Jan de Nul - Vessel 1 - Green Deal validation
report
The government and the maritime sector signed a Green Deal in 2019 to make maritime shipping, inland shipping and ports more sustainable. One aspect of the Dutch Green Deal, is a program for validation of the effects of sustainable maritime solutions. TNO conducted a measurement campaign under the validation program to validate the proper operation and emission claims on a diesel particulate filter (DPF) from emigreen. Validation measurements were performed on the engines of an Ultra low emission vessel (ULEv). On this vessel, a DPF was fitted on top of the TIER III certified engines with OEM SCR system. Where the primary goal of this study is to evaluate the claim of Emigreen with respect to the ULEv particle emission limits, also performance of the SCR system with respect to the ULEv NOx limit value is evaluated. In addition, possible degradation of the system is evaluated with comparison to previous measurements and the performance of in stack NOx sensors is evaluated with certified measurement instruments. Validation of both aftertreatment systems is succesful if particle emissions (particle number and particle mass) remain below the applicable limit values in weighted cycle results, and if nitrogen oxides (NOx) emissions are reduced to levels below the applicable limit. Note that possible adverse side effects from the emission aftertreatment systems on other emission components should be weighted against NOx and particle matter emission reductions as well.
