NORSOK Standards

Developed by the Norwegian petroleum industry, NORSOK standards aim to ensure safety, efficiency, and cost-effectiveness in offshore projects.
NORSOK N-004 (Rev. 3, 2013) defines requirements for structural strength and stability of steel tubular members in offshore environments.
Applies to cylindrical members with thickness ≥ 6 mm, D/t ratio < 120, and yield strength below 500 MPa.

Why Choose SDC Verifier for NORSOK N-004 Compliance

open benchmarks to verify design

Built-In NORSOK Logic

Run automated member and joint checks based on NORSOK N-004 (Rev. 3, 2013), directly inside Ansys, Femap, or Simcenter 3D.

Automated Structural Checks

Perform axial, bending, and combined stress checks on tubular members without manual formulas or spreadsheets.

Fast Joint Verification

Verify tubular joints using predefined formulas and shape recognition—reduce review cycles and errors.

Mesh-Independent Member Detection

Use the Beam Member Finder to auto-detect buckling lengths, independent of mesh size.

Detailed Reports for Certification

Export calculation-ready documentation structured for classification societies and audits.

About the NORSOK N-004 Standard

NORSOK N-004:2013 defines structural strength and stability requirements for offshore steel structures—specifically tubular members used in harsh environments like the North Sea.

Applies to cylindrical steel members with:

Thickness ≥ 6 mm
D/t ratio < 120
Yield strength < 500 MPa

Covers:

Member and joint strength checks
Integrity assessments for damaged or aging structures
Reuse evaluations under new loading or service conditions

This standard follows the design principles of ISO 19900 and references EN 1993-1-1 and NS 3472.

Get NORSOK N-004 Checks Done — Without Spreadsheets

Run member and joint checks in minutes, not hours. Apply Rev.3 (2013) directly in your Ansys, Femap, or Simcenter model. No manual tables. No second-guessing.
