Ballast water treatment system manufacturer DESMI Ocean Guard has announced that it will appeal the US Coast Guard’s preliminary decision[ds_preview] to not accept the most probably number (MPN) method for type approval testing of ballast water treatment systems. On December 14, 2015, the Coast Guard announced their preliminary decision to not accept the MPN method for the verification of the performance of ballast water treatment systems.
DESMI Ocean Guard, together with other manufacturers of UV based ballast water treatment systems, had in March 2015 submitted a Type Approval application to the Coast Guard, using the MPN method to verify performance.
»We are, like many other BWTS providers and shipowners, surprised and disappointed with this preliminary decision, and after having carefully reviewed all available data and information together with our legal counsel, we have decided to file an appeal. We think that Coast Guard’s decision is not right for many reasons, and supported by important legal and scientific facts, we are convinced that the MPN method, which is accepted in the rest of the world, will also become accepted in the US territory,« said the company in a statement.
