NORSOK L-002 is the Norwegian petroleum industry standard for the design, layout, and structural analysis of piping systems on offshore oil and gas facilities. It establishes consistent industry requirements intended to replace individual company specifications, thereby reducing costs and lead times. The current active version is NORSOK L-002:2016. Scope and Applicability

Included: Covers process, drilling, utility, and instrument piping and tubing for offshore facilities, including the upper part of risers, barred tees, and pig launchers/receivers.

Excluded: Does not cover sub-sea pipework, risers (except the upper part), sanitary piping, or marine systems in hulls of floating platforms.

Core Standards: Primary design conditions follow ASME B31.3 (Process Piping), though L-002 may impose more stringent requirements. Key Design and Layout Requirements

The standard provides detailed technical guidelines across several engineering disciplines: Piping Arrangement:

Piping should be arranged on horizontal racks at specific elevations.

Change of direction (longitudinal to transverse) should typically include an elevation change to avoid pockets.

Utility headers (air, water, steam) must be placed on the top of multi-tiered racks. Clearance and Accessibility:

Must provide adequate headroom for safety, inspection, and maintenance, especially for removing pump and compressor shafts or exchanger bundles.

No piping is allowed inside instrument or electrical rooms, except for fire-fighting systems. Valve Installation:

All operational and emergency valves must be accessible from a deck or permanent platform.

Check valves in vertical lines are only permitted if the flow is upward. Safety and Environment:

Requires ergonomic considerations for tools and control devices according to NORSOK S-002.

Flange joints and potential hydrocarbon release points must be located within designated hazardous areas. Structural and Stress Analysis

L-002 defines the criteria for when a comprehensive stress analysis is required:

Temperature & Pressure: Analysis must account for expansion stress based on algebraic differences between minimum and maximum design temperatures.

Loads: Includes considerations for environmental loads, vibration, and bending moments on valves and mechanical joints. norsok l002 pdf

Equipment Protection: Piping must be supported so that thermal expansion or operating loads do not exceed the limits of connected rotating equipment (pumps, compressors) as specified in NORSOK R-001. Referenced NORSOK Standards NORSOK L-002 Piping Design Guide | PDF - Scribd

L-002 is famous among stress engineers for its stringent requirements regarding flexibility and fatigue. Key highlights include:

NORSOK L-002: Piping Design, Layout, and Stress Analysis is a technical standard developed by the Norwegian petroleum industry. The NORSOK standards were originally created to replace individual oil company specifications, thereby reducing complexity and cost while maintaining a high level of safety.

The L-002 standard serves as a comprehensive guideline for the design of piping systems. It does not reinvent the wheel; rather, it acts as a "super-standard" that sits on top of recognized codes (like ASME or ISO) to address specific requirements for offshore installations, floating production storage and offloading (FPSO) units, and onshore refineries in harsh climates.

Note: You should also download NORSOK L-001 (Piping and valves – Procurement and fabrication) as it complements L002.
