It defines and establishes strict welding quality requirements. This includes provisions for welding personnel qualifications, ensuring that only qualified welders work on critical structures. For instance, the specification mandates specific welding acceptance criteria and allows for double-sided welding for all TKY joints with a diameter greater than 600mm.
EEMUA Publication 158 (Third Edition, 2014) is a global standard defining the construction specification for fixed offshore structures, including jackets, support frames, and ancillary components. It establishes technical requirements for materials, welding control, personnel qualification, and inspection (including specific hold times for NDT) to ensure structural integrity.

EEMUA 158 is a harmonized construction specification developed by industry experts, operators, and contractors. It outlines the minimum requirements for the fabrication, welding, inspection, and testing of primary and secondary structural steelwork used in fixed offshore platforms.
EEMUA 158 is not a document to be read in isolation but is part of a larger framework of standards and specifications. It is commonly referenced alongside other EEMUA publications, including:
Specifies the permitted electrodes, fluxes, and filler metals to ensure weld quality and compatibility with parent materials. Free PDFs hosted on unverified forums often miss
: Standards for ultrasonic, magnetic particle, and radiographic inspection. Key Technical Requirements Weldability
The modern Third Edition incorporates updated frameworks extending to offshore wind turbine structures and foundations.

It is frequently modified or supplemented by major energy operators via custom corporate amendments—such as the BP engineering standard GS 118-1. Core Technical Pillars of EEMUA 158
NORSOK is primarily used on the Norwegian Continental Shelf, whereas EEMUA 158 is more common in the UK sector of the North Sea and various international waters. Both standards share similar high-level safety philosophies but differ in specific NDT reporting and testing frequencies.
