US visit does not resolve disagreement
During a business visit to the US this week, which was led on by the Royal Couple and the Minister of Business and Growth Troels Lund Poulsen, the Danish Maritime's Vice President Michael Prehn did not hear any positive notes on ballast water from the Americans, but on the other hand he did not hear any bad ones either.
There was little movement in the US position on the ballast water system. The United States will continue to apply other criteria for ballast water treatment than the IMO Convention that has just been adopted and will go into force in September next year.
After the IMO rules, it is sufficient that the invasive species are not viable and cannot reproduce. USA requires that all biological activity must be stopped, placing an emphasis on a particular sample which must show that the organisms are not "alive".
"This requirement is unnecessary as the invasive species which the rules are meant to keep out, only become invasive if they can reproduce. If they cannot, they disappear in the course of a few hours," says Michael Prehn.
He points out that the demand for this particular test is particularly problematic for the ballast water system using UV irradiation as a disinfectant. About half of the up to now approved facilities do this.
"The US officials could, however, confirm that a common set of rules with IMO was wanted. They could not provide any answers, but we see it as an overall positive message and certainly not the opposite," says Michael Prehn.
