The NORSOK standards are developed by the Norwegian petroleum industry to ensure adequate safety, value adding and cost effectiveness for petroleum industry developments and operations. This NORSOK standard describes a system for coding of cost and weight estimates and as-built/experience data.
The system comprises 3 sets of complementary sub-coding systems named: PBS, SAB and COR.
- Physical Breakdown Structure (PBS): This hierarchical structure defines the Physical/Functional components of «Projects» during any phase of development. The PBS provides a coding structure, which enables any known Oil and Gas Production and processing facility configuration scheme to be coded.
- Standard Activity Breakdown (SAB): This hierarchical structure provides a timescale attribute to express when during the project lifetime, expenditures and activities occur.
- Code Of Resource (COR): This hierarchical structure classifies all project resources and categorizes resources according to primary, secondary and tertiary levels of resources.
The PBS of NORSOK can be compared to the PBS of 3D WBS.
The SAB of NORSOK can be compared to the ABS of 3D WBS.
The COR of NORSOK can compared to the OBS/RBS of 3D WBS.
3D WBS method can be based on NORSOK Standard Z-014 but zones must be added. So, NORSOK Standard Z-014 and 3D WBS method are compatible.
