Have you ever seen a jumble of numbers on a tank's data plate? EEMUA 158 defines a clear marking system (including the "EEMUA 158 shell" symbol) that tells inspectors the maximum working pressure, test date, MAWP, and material group at a glance.
EEMUA 158 outlines rigorous protocols for Welding Procedure Qualifications (WPQs) and Welder Performance Qualifications.

One of the most widely referenced parts of the EEMUA 158 PDF is its NDT defect acceptance criteria. The standard categorizes welds based on criticality (e.g., highly stressed nodes vs. secondary secondary decking). Critical welds require stringent ultrasonic and radiographic evaluations with very low tolerances for internal flaws like porosity, slag inclusions, or lack of fusion. 4.

Developed by the Engineering Equipment and Materials Users Association (EEMUA), Publication 158 was created to address the harsh environmental challenges of the North Sea. While originally regional, its high standards for safety and structural integrity have led to its adoption in offshore projects worldwide. It serves as a comprehensive technical specification for the construction of primary and secondary steelwork. Key Features of the Standard

It defines precise dimensional tolerances for node joints, tubular alignment, and overall structural geometry to minimize fit-up stresses. 3. Non-Destructive Testing (NDT) and Quality Control : Manifold and production system support frames
For standard oil and gas production platforms, jacket foundations, and topside modules, EEMUA 158 remains the primary reference document. Why Accessing the Official PDF Matters
Specifies requirements for structural steel plates, rolled sections, and tubulars.
To get the most out of the EEMUA 158 standard, organizations should follow best practices for implementation, including:
