N-005 Condition monitoring of loadbearing structures (Rev. 1, Dec. 1997)

This NORSOK standard describes principles, functional requirements and guidelines for condition monitoring of the loadbearing structures throughout their operative lifetime until the decommissioning. The standard is applicable to all types of offshore structures used in the petroleum activities, including bottom founded structures as well as floating structures.

The standard is applicable to condition monitoring of complete structures including substructures, topside structures, vessel hulls, foundations, and mooring systems.

The standard covers all aspects related to condition monitoring, including in-service inspection and maintenance planning, implementation, structural integrity evaluation, condition monitoring documentation. Assessment of offshore structures, when the initiators exist, is also addressed.
