German lab ship measures major emission reduction

Brussels [ENA] A German lab vessel has succeeded in a major reduction of its toxic engine output by applying latest technology to control pollution from the inland waterway fleet. The EU’s clean shipping program Clinsh announced today, that the MS Max Pruss, from Recklinghausen, had measured an almost total elimination of certain contaminants with the reduction rate for nitrogen oxide reaching 96 percent and soot 98 percent.

Clinsh (CLean INland SHipping) is a project of inland shipping’s Green Deal assessing the costs and effectiveness of emissions-control technologies and alternative fuels in practice. Launched in 2016 it is supported by the European LIFE fund with a total budget of €8.5m. With its main objective of contributing to a better air quality in urban areas the project is a co-operation between 17 partners from four European countries, including universities, port authorities, local governments and private companies. Under Clinsh some 30 ships have been selected for adjusting propulsion so that the performance of various emission reduction techniques and alternative fuels can be tested.

The Max Pruss is based on the Rhein-Herne-Kanal; built in 1998 it is 33 meters long and equipped with two diesel engines that together produce 680 hp. They were equipped in October 2015 with an SCRT (clean diesel) exhaust gas retrofit system and soot particle filters; thanks to AdBlue additives (a liquid solution of urea, the component found in urine) the system only emits little nitrogen oxides into the environment. The measurements according to Clinsh were carried out in November 2018 and after an evaluation and validation process published now in Brussels. “The results show good reduction rates in all measuring points for all limited pollutants,” Clinsh said in a statement.

For the leading components nitrogen oxide rates were between 66 and 96 percent. Reduction rates for soot were measured as up to 99.8 percent while particulate emissions were reduced by 77.8 to 96.7 percent. On hydrocarbon compounds, reduction rates of between of up to 97.3 percent were achieved. Concerning carbon monoxide reduction rates varied between 31.6 and 62.5 percent. Clinsh chair Rik Janssen said at a meeting in 2018 that the project provided a way for operators to assess the business case for investing in environmental improvements. But shortly, vessels emitting too much particulate matter and nitrogen oxides would be banned from ports including Rotterdam, and that alone was a very good reason to take action, he added.
