The BWM Convention is the diminutive term commonly used when referring to the “International Convention for the Control and Management of Ships' Ballast Water and Sediments”, adopted by the International Maritime Organization (IMO) in February 2004. The Convention is composed of 22 Articles, and one Annex with 5 sections (A to E). Since its adoption, 14 Technical Guidelines have been developed to support port state authorities, shipmasters and owners, equipment manufacturers and class societies, and to encourage the harmonized implementation of the different Requirements.
