In line with the Intertanko-led joint proposal last year, the International Maritime Organization (IMO) has agreed to a rescheduling of the International Ballast Water Management Convention implementation dates, which will smooth the installation scheduling for ships installing ballast water management systems (BWMS), a trial period for port state control and new guidance on BWMS type approvals. At its 65th session, the Marine Environment Protection Committee (MEPC 65) of IMO approved a draft Assembly resolution which recommends that ships not be required to install a BWMS until its first renewal survey after entry into force of the BWM Convention.
