Based on planned IMO compliance deadlines, over 50,000 merchant ships will need to install certified BWT systems by 2016 or 2017; that’s about 10,000 ships per year for five or so years after ratification. Optimarin, a world leader of ballast water treatment systems, is setting its sights on retrofits and newbuilds that represent great opportunity for future business growth. Optimarin today announced global expansion of its company after a period of significant activity, securing BWT system contract wins with a number of major ship owners to be delivered over the next few years.
