ISO 17357-2:2014

Overview

ISO 17357-2:2014 provides internationally accepted requirements for low-pressure floating pneumatic rubber fenders used in ship-to-ship and ship-to-berthing-structure berthing and mooring. The standard specifies materials, dimensions, performance criteria, minimum test and inspection procedures, and marking/documentation requirements for low-pressure fenders. It does not cover methods for selecting the correct fender for a specific application or address safety hazards associated with use.

Key topics and technical requirements

• Fender types and classification
  • Defines two low-pressure types: clamped end (typically ≤ 2.3 m diameter) and moulded end (typically ≥ 2.8 m diameter).
  • Default initial internal pressure: 7 kPa unless otherwise specified.
• Materials
  • Specifies coated textile construction (vulcanized synthetic rubber over high-tenacity woven nylon) and related component definitions (bead rings, end-closure plate assemblies, clamped end fittings).
• Dimensions and ordering
  • Nominal diameter and length requirements, with purchaser information to include ISO number, fender type, initial pressure, size, and colour.
• Performance and testing
  • Prototype performance confirmation and performance curves (guaranteed energy absorption and reaction force considerations).
  • Prototype tests: parallel compression, angular compression, durability, compression recovery, puncture resistance, and recording conditions.
  • Commercial fender inspections: material tests, dimensional inspection, air leakage, and hydrostatic pressure tests.
• Quality assurance
  • Documentation and marking requirements for traceability.
  • Option for inspection/evaluation by a qualified independent inspection service or major classification society.
• Normative references
  • Test methods and rubber/fabric standards referenced (e.g., ISO 37, ISO 48, ISO 815-1, ISO 1421, ISO 1431-1, ISO 2411).

Applications and who uses it

ISO 17357-2 is intended for manufacturers, naval architects, port/terminal engineers, ship operators, procurement teams, and classification societies involved with:

• Specification and manufacture of marine fenders for berthing and mooring operations.
• Verifying fender performance and conformance through prototype and commercial testing.
• Preparing procurement documents and ensuring supplier quality control and traceability. The standard is a technical reference for product quality and test methods; users should combine it with operational risk assessments and energy-absorption selection methods not covered by this part.
