As of July 2021, about 20,500 ships worldwide had already been fitted with ballast water treatment systems (BWTS) or had ordered their installation. This left some 35,000 vessels in the global fleet without BWTS. By 2024, all of these remaining vessels will need to be retrofitted with BWTS to comply with the 2004 IMO regulation on the management of ballast water and sediments.
