Overview

EN 15271:2007 - "Inland navigation vessels - Studless anchor chain - Anchor equipment" (CEN) specifies safety, design and marking requirements for anchor equipment used on inland navigation vessels. The standard covers anchor equipment as defined by Annex II of Directive 2006/87/EC and complements related standards for anchor chain, winches and accessories. It ensures safe stowage, secure end fastenings and reliable chain stoppers for studless anchor chain systems.

Key topics and technical requirements

• Scope and components covered
  • Anchor equipment includes windlass (EN 13711), chain lifter (EN 14874), accessories (EN 14606), anchor chain (EN 14330), anchor equipment per EN 15271 and the anchor itself.
• Chain locker
  • Must accommodate the entire anchor chain length without outside aid and prevent accumulation of water/solids (e.g., perforated plate storage).
• End fastening
  • Must be easily accessible in emergencies and detachable safely with a simple tool; bolted shackles are not permitted.
  • Strength: end fastening must withstand a minimum breaking load 20% greater than the chain (per EN 14330) without permanent deformation.
• Chain stopper
  • Must hold the chain when the windlass is released and be simple/safe to operate.
  • Manual unlocking force for unloaded chain must not exceed 350 N.
  • Must not damage chain when loaded to 80% of production test load and remain functional afterward.
• Materials
  • Chain stoppers must have mechanical properties at least equivalent to round steel link chain (EN 14330); grey cast iron is not suitable for end fastenings or stoppers.
• Manufacturer requirements, designation and marking
  • Manufacturer must declare conformity.
  • Components are designated (e.g., cloc, endf, cstop) and must be permanently stamped with EN 15271, nominal chain size (e.g., 30 x 84) and manufacturer mark.
• Annex B - Calculation aids
  • Provides formulas for anchor mass (P = k · B · T), coefficients based on vessel characteristics, minimum chain lengths (e.g., 40 m minimum, rules by vessel length), and minimum breaking load calculations for chains.

Applications and who uses this standard

• Shipyards and naval architects designing inland vessels
• Manufacturers of anchor chains, end fastenings and chain stoppers
• Vessel operators and owners ensuring equipment compliance
• Inspectors, classification societies and regulatory authorities enforcing Directive 2006/87/EC requirements
• Safety engineers and procurement teams specifying deck equipment
