The hype around the use of open-loop scrubbers is risking the loss of focus on key issues of human health and the environment, the Exhaust Gas Cleaning Systems Association (EGCSA) has said.

Polaris Shipping will install open-loop scrubbers on seven of its ships, using Langh Tech systems and retrofitting at South Korea’s STX Offshore & Shipbuilding.

Last week’s announcement by the Maritime & Port Authority of Singapore (MPA) that it would ban open-loop scrubbers from its port waters from 1 January 2020 when IMO’s 0.5% global sulphur cap comes into force has set the cat among the pigeons for a growing number of owners opting to for exhaust gas cleaning for compliance with the regulation.

The world’s busiest port Singapore is to ban the use of open-loop scrubbers in its waters and ships will have to use compliant fuel once the IMO 2020 sulphur cap comes into force.
