Inland navigation vessels - Outboard ladders

This document is applicable to outboard ladders for inland navigation vessels. Outboard ladders are used on inland navigation vessels having great side heights to facilitate safe climbing into ship's boats, safe disembarking or safe crossing over onto vessels in the case of significantly different boarding heights.
This document specifies safety requirements on design, dimensions and strength and test conditions for outboard ladders.
Outboard ladders are intended for that range where boarding stairs according to EN 1502 are not sufficient in length. This range starts at a boarding height of approximately at 2,8 m above the light water-line.
Outboard ladders are not intended for use by passengers.

Fahrzeuge der Binnenschifffahrt - Außenbordleitern

Dieses Dokument ist anwendbar für Außenbordleitern für Fahrzeuge der Binnenschifffahrt. Außenbordleitern werden auf Fahrzeugen der Binnenschifffahrt mit großer Seitenhöhe eingesetzt, um den sicheren Einstieg in Beiboote, den sicheren Übergang zum Land oder das sichere Übersteigen zu benachbarten Schiffen bei sehr unterschiedlichen Bordhöhen zu ermöglichen.
Dieses Dokument legt Sicherheitsanforderungen an Bauart, Maße und Festigkeit sowie Prüfbedingungen für Außenbordleitern fest.
Außenbordleitern sind für den Bereich vorgesehen, in dem Außenbordtreppen nach EN 1502 bezüglich ihrer Länge nicht ausreichen. Dieser Bereich beginnt bei einer Bordhöhe von ungefähr 2,8 m über der Leerwasserlinie.
Außenbordleitern sind nicht für die Benutzung durch Fahrgäste vorgesehen.

Bateaux de navigation intérieure - Échelles de bordé

Le présent document est applicable aux échelles de bordé pour les bateaux de navigation intérieure. Les échelles de bordé sont utilisées sur les bateaux de navigation intérieure avec de grandes hauteurs de muraille pour assurer la sécurité des transferts vers les canots, du débarquement sur la terre ferme ou du passage sur des navires à pont inférieur lorsque les hauteurs pour l’embarquement sont significativement différentes.
Le présent document spécifie les exigences de sécurité relatives à la conception, aux dimensions, à la résistance et aux conditions d’essai pour les échelles de bordé.
Les échelles de bordé sont conçues pour la gamme de bateaux de navigation intérieure pour lesquels les escaliers de bordaille conformes à l’EN 1502 ne sont pas suffisamment longs. Cette gamme démarre à une hauteur de bord de plus d’environ 2,8 m au-dessus de la ligne d’eau à vide.
Les échelles de bordé ne sont pas destinées à être utilisées par les passagers.

Plovila za celinske vode - Zunanje lestve

Ta dokument se uporablja za zunanje lestve za plovila za celinsko plovbo. Zunanje lestve se uporabljajo na plovilih za celinsko plovbo z veliko bočno višino, da se omogoči varen vstop na plovilo, izkrcanje ali varno prestopanje na plovila v primeru zelo različnih višin vkrcanja.
Ta dokument določa varnostne zahteve glede zasnove, dimenzij in trdnosti ter preskusne pogoje za zunanje lestve.
Zunanje lestve so namenjene tistim razponom, kjer stopnice za vkrcanje v skladu s standardom EN 1502 niso dovolj dolge. Ta razpon se začne pri višini vkrcanja približno 2,8 m nad vodno gladino pri lahki teži plovila.
Zunanje lestve niso namenjene potnikom.

Overview

EN 17361:2023 (CEN) is the European standard for outboard ladders used on inland navigation vessels. It specifies safety requirements for design, dimensions, materials, strength and test conditions for ladders used where conventional boarding stairs (EN 1502) are too short - typically for boarding heights from approximately 2.8 m above the light water-line. Outboard ladders covered by this standard are intended for crew use (not passengers) and exist in Type A (rigid holder) and Type B (adjustable hook) forms.

Key topics and technical requirements

• Scope & purpose: Ladders to facilitate safe climbing into ship’s boats, disembarking or crossing between vessels when large side heights occur.
• Dimensions & construction:
  • Stringers/handholds typically tubular Ø 35 mm ± 5 mm; rungs as rectangular hollow profiles (e.g. 40 × 30 mm).
  • Platform made of water-displacing sheet; treads must be non‑skid.
  • Spacers (suggested pipe Ø 30 mm) fitted at specified positions to keep ladder clear of hull.
  • Table of standard step counts and maximum permissible masses (examples: 10‑step ≈ 15.5 kg, 16‑step ≈ 21.5 kg).
• Materials: Suitable materials include aluminium or FRP (fibre reinforced polymers); exposed surfaces must resist weather, UV, oil/fuel. Fasteners for adjustable hooks per EN ISO 3506.
• Strength & loadings:
  • Rungs and platform rated for 1.5 kN; design must withstand two simultaneous rated loads (top and bottom rung).
  • Strength testing applies 2.5 kN loads for 60 s per rung/platform; after testing there must be no permanent deformation.
  • Handhold design load 0.3 kN (tested with 0.5 kN in the standard).
• Watertightness & buoyancy: Hollow sections and connections must be watertight; the ladder shall be buoyant.
• Testing & conformity:
  • Type testing for series production (sample 1 per max. 20 units).
  • Material certificates required; visual, measurement and functional tests as specified.
• Designation & marking: The standard includes requirements for identification and marking of the outboard ladder.

Applications and who should use it

• Shipbuilders and naval architects designing inland navigation vessels
• Ladder and marine equipment manufacturers (outboard ladders, adjustable hooks)
• Vessel owners/operators and shipyards specifying safe access equipment
• Classification societies, port authorities and regulatory bodies enforcing safety compliance
• Safety officers and procurement teams selecting compliant boarding solutions

Related standards

• EN 1502 (boarding stairs) - use where outboard ladders are not sufficient
• EN 22768-1 (general tolerances)
• EN ISO 3506-1 / EN ISO 3506-2 (stainless steel fasteners)
• EN ISO 14122-2 (non‑skid treads guidance)
• EN 485-1 / EN 754-1 (aluminium product references)
