ICS Code (Other standards related to shipbuilding and marine structures): 47.020.99
scope:

This part of ISO 11711 provides guidance to shipboard personnel and other concerned parties on the materials, design and installation of permanent shipboard fittings used to facilitate the sampling of ballast water from the main discharge pipe on board a vessel. The guidance is limited to ships with a ballast discharge pipe size of DN 100 or greater. Smaller ballast pipe diameters will be addressed in Annex A. Sampling is intended to determine if ballast water is in compliance with regulatory discharge standards, such as during the installation of ballast water treatment equipment, periodic ballast water discharge assessments, or when a port state control inspection indicates there is a need to sample the ballast water being discharged. In addition, sample ports may need to be installed on ships used as platforms to conduct verification testing of ballast water management systems (BWMS). In this case, uptake and discharge samples would need to be collected. Guidance for installation of sample ports intended to collect uptake samples is provided in Annex B. A sampling team will need to coordinate with the vessel to install a sample collection probe into the shipboard sample port as needed to collect ballast samples, and the port will be sealed with a blind flange at other times. ISO 11711 provides guidance on the location of sample ports to accommodate representative sampling, and it standardizes the presentation of the port to accommodate various probe configurations. Part 1 of ISO 11711 also identifies the need for a return port to the ballast line downstream of the sample collection port, which will allow processed sample water to be returned to the ballast pipe. The specific sample probe and other sample collection apparatus will be determined by the sample collection team according to the requirements of ISO 11711-2. NOTE - The distinction between the sample port discussed in Part 1 and the sample probe discussed in Part 2 is important. The sample port is a permanent apparatus designed and installed in the ship's ballast piping to accept multiple sample probe configurations. The sample probe is a temporarily installed water collection pipe designed by the sampling party to mate with the sample port and to meet the measurement objectives of the sample.
