Inland navigation vessels - Manually- and power-operated coupling devices for rope connections of pushing units and coupled vessels - Safety requirements and main dimensions (ISO 6218:2019)

This technical specification establishes essential safety requirements and principal dimensions for coupling devices used to connect pusher units with to-be-pushed vessels in inland waterway navigation. The document addresses both manual and power-operated systems, ensuring reliable mechanical and functional integration between the pushing vessel and the barge or vessel being pushed. It defines critical parameters for rigging lines and connection mechanisms to prevent operational failures that could compromise vessel stability or crew safety during maneuvering operations. The scope covers design criteria, material specifications, and performance testing methods for these coupling assemblies. Compliance with these provisions facilitates uniformity in equipment manufacturing and operational procedures across different regions utilizing inland waterway transport systems. By standardizing connection methods, the document supports the safe interaction between propulsion units and pushed vessels, reducing risks associated with separation or structural stress during transit. The guidelines serve as a reference for engineers, manufacturers, and operators involved in the design, maintenance, and deployment of inland waterway pushing systems, promoting consistent safety levels throughout the industry.
