Overview
EN ISO 6218:2019 (ISO 6218:2019) is the CEN-endorsed international standard for coupling devices used on inland navigation vessels. It covers manually‑ and power‑operated coupling devices for rope connections applied when assembling push tows or coupling vessels alongside. The standard specifies safety requirements, main dimensions, designation and testing rules to ensure stable positioning of coupled vessels and to protect operators during creation, operation and separation of rope connections.
Key topics and requirements
- Scope and application: Requirements for coupling devices used in push‑tow and alongside coupling operations on inland waterways.
- Safety requirements (Clause 4): General safety principles for components and operation to protect operators from accidents during assembly, operation and separation of rope connections.
- Design and construction (Clause 6): Requirements for rope drums, handwheels, power‑operated equipment, brakes, arresting and protective devices, guide tracks and foundations.
- Dimensions and characteristic values (Clause 7): Main dimensional rules and characteristic values for manually and power‑operated coupling devices.
- Material and markings (Clauses 8 and 11): Material considerations and required marking for identification and safe use.
- Operating and assembly instructions (Clause 9): Mandatory user, assembly and maintenance information to accompany devices.
- Testing and designation: Normative provisions for individual and type testing (Annex A) and examples of designation.
- Notable technical updates (2019 edition):
- The previous limitation on rope speed was removed.
- Minimum drum diameter requirement changed to 12 × maximum rope diameter.
- Terminology updated from “wire rope” to “rope” to cover both wire and textile ropes.
Practical applications
Who uses EN ISO 6218:2019:
- Shipbuilders and naval architects specifying coupling device interfaces for inland navigation vessels.
- Manufacturers of manually and power‑operated coupling devices designing to standard dimensions and safety rules.
- Vessel operators and ship crews for safe operation and maintenance of push tow and coupled configurations.
- Classification societies, regulatory bodies and procurement teams for conformity assessment and equipment acceptance.
- Testing laboratories performing type and individual equipment tests per the standard.
Primary use cases:
- Designing and installing coupling systems for push tugs, barges and coupled convoys.
- Ensuring operator safety during mooring, coupling and decoupling operations.
- Specifying procurement requirements and performing acceptance testing.
