Full Description
ISO 11711-1:2013 provides guidance to shipboard personnel and other concerned parties on the materials, design, and installation of equipment used to take samples of treated ballast water from the ballast water 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 ballast water management system (BWMS) is working as designed, i.e. 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.
