Singapore’s Maritime Port Authority (MPA) has announced that from Jan. 1, 2020 the wash water generated from open-loop scrubbers will be banned in Singapore. This is a potential setback to shippers that have invested millions in the exhaust gas cleaning systems. Ships fitted with hybrid scrubbers will be required to switch to the closed-loop mode of operation and Singapore will be providing facilities for the collection of residue generated from the operation of these scrubbers. As a the world’s largest bunkering port, the MPA is working closely with bunker suppliers to ensure an adequate supply of compliant fuel in its port well ahead of the 1 January 2020 deadline. A list of suppliers that can supply compliant fuel will be made available from the middle of 2019.
