NORSOK N-005

Includes Corrigendum AC, January 2019.

NORSOK N-005 contains principles, practices, functional requirements and guidelines for the integrity management of offshore structures and marine systems throughout their life, including time until decommissioning and final removal.

This standard is applicable to all types of offshore load-bearing structures used in petroleum activities, including substructures, topside structures, vessel hulls, foundations, mooring systems and marine systems such as water and weather tight systems, stability systems and station keeping systems.

This standard covers all aspects of integrity management, including the management of data, inspection and/or monitoring strategies, inspection and/or monitoring execution, integrity evaluation and integrity assessment.

The assessment of existing offshore structures to be operated beyond original requirements is addressed in NORSOK N-006. Initiators for when such assessment is needed are covered in that standard, in accordance with NORSOK N-001.
