    About Standard

      SDC Verifier

    The IACS UR S35 standard—issued by the International Association of Classification Societies—defines mandatory rules for evaluating the buckling strength of unstiffened plates used in ships and offshore structures. It ensures that plate elements can withstand compressive, in-plane, and shear forces without failure.

    Objective: Prevent buckling-related failures in marine and offshore environments by establishing a uniform strength assessment methodology.

    Scope of Application:

    • Hulls of ships and offshore platforms
    • Bulkhead, deck, and cargo hold plates
    • Oil rigs, FPSOs, and naval structures

    Engineering Impact: By applying UR S35, naval architects and structural engineers can:

    • Optimize plate thickness while maintaining safety margins
    • Identify failure-prone regions early in the design
    • Align with latest IACS classification society requirements

    The 2023 revision (Corr. 1, Sep. 2024) reflects updated methods and safety factors for robust structural integrity in demanding offshore conditions.

    Frequently Asked Questions

    What is IACS UR S35 Plate Buckling?

    It’s a standard developed by the International Association of Classification Societies to evaluate the buckling strength of unstiffened plates in ships and offshore structures under various loading conditions.

    Which industries benefit from this standard?

    Primarily shipbuilding and offshore engineering — particularly naval architects and structural engineers working on hulls, bulkheads, decks, oil rigs, and FPSOs.

    Does SDC Verifier automatically recognize plate sections?

    Yes. The Panel Finder tool in SDC Verifier detects and defines sections and plates, streamlining the setup for buckling checks.

    Can I edit plate dimensions manually?

    Yes, you can override default values and define plate thickness manually if needed.

    How do I enable IACS UR S35 in SDC Verifier?

    Navigate to Standards → Main → Other → IACS UR S35 Plate Buckling (2023). Custom settings can be adjusted from the Help panel.
