Title: NORSOK P-002 – Process Design Principles
Scope and Application: NORSOK P-002 is a governing document that specifies the technical requirements for the design of process plants and systems on offshore installations. While it works in tandem with NORSOK P-001 (Process Design), P-002 focuses heavily on the mechanical integrity and layout specifics of piping systems. The only legal and safe way to obtain
Key Features of the Standard:
1. Piping Material Selection One of the most utilized sections of P-002 is the material selection guide. It defines the acceptable materials for different process services (e.g., carbon steel, stainless steel, duplex, titanium) based on the fluid being transported (e.g., produced water, gas, oil, seawater). It provides specific guidance on corrosion allowances and fluid categories.
2. Design Conditions The standard sets the parameters for: Specifies controllers, I/O (distributed vs
3. Piping Class Specifications NORSOK P-002 often references or defines piping classes. These are detailed tables that specify the exact components (flanges, valves, gaskets, bolts) allowed for a specific pressure-temperature rating and fluid service. This ensures standardization across a facility, reducing the need for custom engineering on every component.
4. Layout and Safety It provides requirements for the physical arrangement of piping, including:
5. Valve Requirements The standard dictates the type and rating of valves to be used in critical services. This includes requirements for ESD (Emergency Shutdown) valves, blowdown valves, and check valves, ensuring they meet the stringent reliability requirements of the North Sea sector.
