THE Clean Shipping Alliance (CSA) 2020 has welcomed the preliminary results of an independent study presented by CE Delft, a research organisation in the Netherlands specialising in environmental issues.
"We hope that the CE Delft study, along with other recently published scientific research, will help answer remaining questions surrounding the environmental impact of scrubber wash water," said CSA 2020 executive director Ian Adams.
The study indicates that accumulated concentrations of exhaust gas cleaning systems (EGCS, or "scrubbers") wash water components are at very low levels and well below applicable regulatory limits.
The study, presented to international delegates of the 74th session of IMO's Marine Environment Protection Committee (MEPC) on 14 May in London, will help inform the current debate regarding the environmental impact of open loop scrubbers on the marine environment, and particularly on ports and harbours.
Along with a similar study conducted by Japan's Transport Ministry, it is expected that the CE Delft research, will help fill important gaps in the scientific record.
The research, carried out by CE Delft in collaboration with Deltares, an independent institute for applied research in the Netherlands, uses three versions of Deltares' state-of-the-art dynamic computer modelling system MAMPEC.
Each version represents a common configuration of European ports, and the study assumes that multiple ships in each modelled port are using open loop scrubbers around the clock throughout the year.
