- It highlighted the focus on wash water accumulation in port waters in Europe.
- The report focusses on wash water accumulation in European ports and the concerned limits.
According to an article published in Ship and Bunker news, a new study has highlighted that wash water from open-loop scrubbers had a minimal effect on seawater quality.
What is a scrubber?
Scrubber equipment allows a ship to continue to use high sulfur fuel oil as the sulfur is removed by a washing process. The wash water can either be discharged into the sea or held the onboard ship for discharge to port facilities.
Research highlights
- The new study was undertaken by C E Delft and commissioned by Cruise Lines International Association Europe, Interferry and European Community Shipowners’ Associations.
- It highlighted the focus on wash water accumulation in port waters in Europe. The preliminary conclusions highlighted that using open-loop EGCS increases the equilibrium concentration in the port by 0% – 0.01% of the annual average environmental quality standard in the European Union in 2021.
- For four compounds, “naphthalene, nickel, benzo(a)pyrene, and fluoranthene, open-loop EGCSs increase the equilibrium concentration in the port by 0.02% – 0.2%“ for the same standard.
- The limit value is set by the annual average environmental quality standard in the EU in 2021.
IMO to be informed
The findings of the report will be passed over to IMO on scrubber pollution and will be presented to the next pollution prevention and response sub-committee (PPR7) meeting which is reviewing the 2015 guidelines for EGCS operation.
