The International Maritime Organisation (IMO) has developed the International Convention for the control and Management of ship’s Ballast water and Sediments (the BWM Convention) to regulate discharges of ballast water and reduce the risk of introducing non-native species. The convention will require ballast water treatment to be used in place of ballast water exchange. This requirement will be phased in, and based on ships’ year of construction. The BWM Convention will apply to all ships’ trading internationally that carry ballast water, although there are some exceptions. There are also special territorial requirements. These are detailed in the National Ballast Water Management Requirements guide.
Entry Into Force
The Convention will come into force 12 months after the date by which not less than 30 states (the combined merchant fleet of which constitutes not less than 35% of the gross tonnage of the world’s merchant shipping) have ratified it. As of Nov 30th 2011, it has been ratified by 31 states, however these states only constitute 26.44% of world shipping (approx).
So ratification is close, and it is estimated 60,000 vessels will need to be fitted with type approved BWT (Ballast Water Treatment) systems at a total cumulative cost of around U.S. $30 billion, with the majority of this being retro-fitting to existing vessels. The opportunity therefore is clear for ship repair and conversion yards such as those operated by A&P in the UK.
