This is the "golden rule" section. It dictates:

Piping must be designed so that equipment (pumps, compressors) can be dismantled without removing permanent valves or adding temporary supports.

Note: Older revisions (Rev. 3, Rev. 2) are no longer valid for new contracts.

A fundamental aspect of NORSOK L-002 is its relationship with the internationally recognized ASME B31.3 code, "Process Piping." NORSOK standards are "normally based on recognised international standards, adding the provisions deemed necessary to fill the broad needs of the Norwegian petroleum industry".

: Defines criteria for numbering systems, clearance requirements (e.g., 40 mm vertical clearance for skids), and efficient routing of process, drilling, and utility piping. Structural & Stress Analysis norsok l-002 pdf

Criteria for analyzing thermal expansion and dynamic loads.

A common point of confusion is the standard's edition status and its "withdrawn" designation. This is the "golden rule" section

A pipe is only as good as its support. NORSOK L-002 provides detailed requirements for the design and selection of pipe supports. This includes standardizing support types to reduce procurement costs and ensuring that supports can handle the dynamic loads often found on offshore platforms.

For acoustic insulation, the standard maps its requirements closely to international acoustic pipe insulation classes.

: Outlines methodologies for analyzing stresses under various operating conditions, including calculations for drag pressure and blast loads. Safety & Accessibility

Hot and cold piping must be grouped separately, with uninsulated hot lines placed at higher elevations. 3, Rev

The standard strictly forbids bolting a NORSOK compact flange to an ASME raised-face flange without an approved adaptor spool. The difference in gasket contact stress leads to guaranteed leaks.

Weight of the pipe, insulation, valves, and the process fluid.
