This document specifies requirements for the design and the fitting arrangements of ballast water discharge sample ports. In coordination with the vessel, a suitable sample collection probe is installed into the shipboard sample port as needed to collect ballast samples, and the port is sealed with a blind flange at other times. This document addresses the location of sample ports to accommodate representative sampling, and it standardizes the presentation of the port to accommodate various probe configurations. It provides specifications for a return port to the ballast line downstream of the sample collection port, allowing processed sample water to be returned to the ballast pipe. The appropriate sample probe and other sample collection apparatus is determined by the sample collection team according to the requirements of ISO 11711‑2. NOTE The distinction between the sample port discussed in this document and the sample probe discussed in ISO 11711-2 is worth noting. 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. This document is applicable to ships with a ballast discharge pipe size of DN 100 or greater, with turbulent flows. Guidance for smaller ballast pipe diameters is given in Annex A. This document primarily addresses the collection of ballast water discharge samples. Optional requirements for installation of sample ports intended to collect uptake samples are provided in Annex B.
Abstract
Overview
ISO 11711-1:2019 - Ships and marine technology - Aquatic nuisance species - Part 1: Ballast water discharge sample port - specifies requirements for the design and installation of permanent ballast water sample ports in shipboard ballast discharge piping. The standard standardizes port presentation to accept multiple sample probe configurations, defines a downstream return port for processed sample water, and addresses location, colour coding and labelling to support representative sampling of ballast water prior to discharge. ISO 11711-1:2019 applies primarily to ships with ballast discharge pipe sizes of DN 100 or greater and assumes turbulent flow; guidance for smaller diameters is given in Annex A and optional uptake-sampling provisions are in Annex B.
Key Topics
- Sample port vs. sample probe: The sample port is a permanent, flanged access installed on the ballast pipe. The sample probe is a temporary collection tube inserted by the sampling team (see ISO 11711‑2 for probe selection and use).
- Location and hydrodynamics: Port placement is specified to enable representative sampling of ballast discharge flows (turbulent conditions required).
- Return port: Specification for a flanged return opening downstream of the sample port so processed sample water can be returned to the ballast line.
- Fitting arrangements and materials: Ports, isolation valves and ancillary piping must comply with applicable classification rules and referenced standards (e.g., flange and valve dimensions, welding qualifications).
- Colour and labelling: Sample and return ports (including valve handles) shall be coloured green per ISO 14726 and clearly labelled for visibility from deck/working platforms.
- Safety and installation practice: Addresses safe access, sealing (blind flange when not in use), and installation guidance to minimize biofouling or operational hazards.
Applications
ISO 11711-1:2019 is used by:
- Ship designers and naval architects integrating permanent sampling ports into new builds.
- Ship owners and shipyards performing retrofits or ballast system modifications.
- Ballast water management system (BWMS) installers and service teams validating treatment performance.
- Port State Control inspectors and on-board sampling teams conducting compliance sampling against discharge standards (e.g., IMO D‑2).
- Marine surveyors and operators creating shipboard sampling procedures and maintenance plans.
Practical benefits include consistent port configuration to accept multiple probe types, easier and safer on-board sampling, and improved reproducibility of ballast water monitoring and compliance testing.
Related Standards
- ISO 11711‑2 (on‑board ballast water sampling and sample processing) - complements ISO 11711‑1 by specifying probes and sampling apparatus.
- ISO 14726 - shipboard piping identification colours.
- ISO 7005‑1, ISO 17602, ISO 15614 - referenced for flanges, valve dimensions and welding qualification.
