Determination and modelling of NO_X and particulate matter (PM) emissions from inland vessels at berth

Results from the EU Life Project „Clean Inland Shipping“ (CLINSH)

The emissions from loading and berthing operations in the ports have so far been determined in NRW by estimations based on the cargo turnover. There was no applicable method for estimating emissions based on differentiated data on the number of moored ships. For this purpose, a methodology was developed and tested by the LANUV within the framework of CLINSH. An important component is the analysis of the current generator stock on cargo vessels, tankers and river cruise ships and the mean emission factors per ship type and length class derived from this. In combination with the survey of the actual energy demand, the number of ships in port, the loading operations and the average berthing times, it was possible to carry out a more realistic estimate of the emissions. It turned out that the emissions determined are significantly lower than previously assumed. For the year 2028, emission quantities of 15.5 t NO_X and 764 kg PM were determined for the Port of Duisburg. In the same year, 9.5 t NO_X and 588 kg PM were emitted by moored ships in the port of Neuss. The berths of river cruise ships “on tour” and the unloading berths of tankers emerged as potential locations for significant reductions in emissions through onshore power supply.
