Overview
EN ISO 10855-2:2024 - titled Offshore containers and associated lifting sets – Part 2: Design, manufacture and marking of lifting sets (ISO 10855-2:2024) - specifies technical requirements, marking and conformity statements for lifting sets used with offshore containers. It covers single- and multi-leg slings including chain slings, wire rope slings, and associated shackles used in offshore lifting operations. The standard is intended for the offshore industry (oil & gas, lower carbon energy) and is adopted by CEN as EN ISO 10855-2:2024.
Key topics and technical requirements
- Scope and terminology: Defines lifting set, sling, assembly-secured components and related symbols (e.g., WLL values and sling angles).
- Design and strength: Requirements for dimensions and structural strength of lifting sets and individual sling legs.
- Chain and wire rope slings: Specific criteria for chain slings (short link) and wire rope slings used in offshore service.
- Shackles and fittings: Requirements for forgings and fitment, including provisions for assembly-secured shackles.
- Materials and testing:
- Impact testing and Charpy references (ISO 148-1)
- Hardness requirements (recently clarified for chain and link components)
- Welding procedure qualification (ISO 15613)
- Corrosion protection and material certificates (ISO 10474)
- Certificates and conformity:
- Preparation of component and sling certificates, plus required documentation
- Statements of conformity for manufactured lifting sets
- Marking: Mandatory marking details (WLL, identification tags), with an example tag for chain slings included in Annex B.
- Calculation guidance: Annex A provides the method to determine minimum required working load limit (WLL,min) of a lifting set.
- Regulatory context: Annex C lists regulations relevant to offshore containers; ISO 10855 series aligns with IMO MSC/Circ.860.
Practical applications
- Use ISO 10855-2 when specifying or procuring offshore lifting sets, to ensure design, manufacture and marking meet recognized international requirements.
- Apply the standard for product certification, quality control, and preparation of conformity documentation.
- Reference during design reviews and supplier audits to verify material testing, welding qualification and corrosion protection practices.
- Use the marking and WLL calculation provisions to ensure safe selection of lifting equipment during offshore lifts.
Who should use this standard
- Manufacturers of offshore containers, chain and wire rope slings, and shackles
- Offshore lifting designers and structural engineers
- Purchase, inspection and certification bodies (third‑party inspectors)
- Offshore operations, rigging and lifting supervisors, and safety managers
