In the demanding environment of offshore petroleum production, standardized engineering practices are essential for maintaining safety and operational efficiency. The NORSOK P-002 standard, titled "Process System Design," is a foundational document developed by the Norwegian petroleum industry to ensure topside facilities are designed with maximum safety and cost-effectiveness in mind. This standard replaces individual company specifications, providing a unified framework for projects on the Norwegian Continental Shelf.

While I couldn't find a direct link to a free download of the NORSOK P-002 PDF, I can suggest some alternatives:

SIL, MTTF, PFDavg, HMI, ESD, PSD, HIPPS, etc.
