Ballast water management system (BWMS) manufacturers and others have mounted a challenge to the US Coast Guard’s (USCG’s) ruling in December that the ‘most probable number’ analysis method for assessing treatment equipment is not acceptable.
The ruling affects UV-based technology in particular and the decision was addressed specifically to four manufacturers – Hyde Marine, Trojan Marinex, Desmi Ocean Guard and Alfa Laval – that had filed applications in 2014 for MPN to be an acceptable method. Apart from Hyde Marine, they have completed their shipboard and land-based testing and submitted type-approval applications based on MPN analysis.
