Overview
EN 29367-2:1994 (identical to ISO 9367-2:1994) specifies minimum lashing and securing requirements for semi-trailers when transported on roll-on/roll-off (Ro/Ro) ships. The standard defines required lashing-point design, location, strength and testing, markings and operational features (brakes, air suspension, jacking points), plus informative annexes that describe typical ship deck securing arrangements and design guidance to reduce damage during handling.
Keywords: EN 29367-2:1994, ISO 9367-2, lashing points, semi-trailers, Ro/Ro ships, maritime securing.
Key topics and technical requirements
- Scope: Minimum requirements to allow efficient lashing/securing of semi-trailers (as defined in ISO 3833) on Ro/Ro ships; annexes provide shipboard securing point patterns (IMO guidance) and damage-reduction design tips.
- Lashing points:
- Types: hinged, fixed or swivelling.
- Number: Semi-trailers >20 t and ≤40 t must have at least four pairs of lashing points; manufacturers must specify suitable numbers for other masses.
- Location: Defined vertical, transverse and longitudinal zones on the trailer; longitudinal layout matches common ship deck spacing (typical 2 500 mm intervals).
- Geometry: Each lashing point must allow a free passage of a circle ≥80 mm diameter and permit engagement of hooks of at least 25 mm opening.
- Strength & testing: Minimum design/test load 120 kN per lashing point; testing direction specified (plane at 60° to horizontal/transverse planes).
- Operational features:
- Trestle (support) location guidance relative to fifth-wheel and goose-neck (ISO 1726 referenced).
- Markings and information plate: Brightly painted lashing points; information plate (200 × 150 mm) showing number of lashing points per side and trestle symbol.
- Parking brake, air-suspension lockout, jacking-up points, rear underrun protection and raised support legs requirements for safe handling and stowage.
- Annex A: Ship deck securing point spacing (longitudinal ≤2 500 mm; transverse 2 800–3 000 mm preferred) and minimum securing point strength (120 kN).
- Annex B: Design indications to reduce damage (frame reinforcement near trestle, bumper design, recessed fittings).
Applications and users
- Who uses it: semi-trailer designers and manufacturers, Ro/Ro shipowners/operators, port terminal planners, cargo stowage and lashing operatives, vehicle inspectors and regulators.
- Practical uses:
- Designing trailers to be Ro/Ro-compatible and easy to secure.
- Specifying lashing points, markings and information plates to meet port/ship requirements.
- Preparing stowage plans and safe lashing procedures in Ro/Ro terminals.
- Reducing handling damage and ensuring compliance with shipboard securing systems.

This standard is essential for safe, compliant sea transport of semi-trailers on Ro/Ro vessels and for minimizing damage and handling risks during shipboard operations.
