(1) The Ballast Water Management Convention will probably not enter into force
before the first implementation date for ballast water treatment
systems (i.e. 01 January 2009 for ships with a ballast water
capacity of less than 5,000m3).
(2) This implies that ships constructed after 01 January 2009 and having
ballast capacity of less than 5000m3 will not have to
install treatment systems on these vessels until their second annual
surveys, but not later than 31 December 2011.
