The intent of this specification is to provide guidance to shipboard personnel and other concerned parties on the materials, design, and installation of equipment for its use, to take samples of treated ballast water from the discharge pipe onboard a vessel. The purpose of the sampling system is to enable the taking of a representative sample in order to verify that the treatment system is working as designed; that is, the treatment is reducing the concentration of living organisms to levels established in discharge standards. The intent of the sampling installation is to provide a representative sample of the ballast water effluent with adequate pressure and flow.
