For new projects, use DNV-CG-0285. For legacy projects or client-specific specs, stick to DNV-CP-0338.
In the high-stakes world of offshore energy and subsea telecommunications, a cable is only as good as its weakest protective layer. While much of the industry focuses on bandwidth or power ratings, the unsung hero of reliability is often the abrasion resistance of the external sheath. dnv-cp-0338
Enter . Officially titled "Cathodic Protection Design," this standard is part of the DNV (Det Norske Veritas) recommended practice (RP) B401 family, updated for modern subsea challenges. While DNV-RP-B401 (now superseded by DNG-CG-0285) was the gold standard for decades, DNV-CP-0338 represents a specific evolution or a project-specific modification of these principles. For new projects, use DNV-CG-0285
DNV-CP-0338 is more than a technical document—it is the foundation of reliable corrosion control for the global offshore energy industry. Whether you are designing a small subsea tieback or a massive deep-water floating production unit, following its rules ensures: While much of the industry focuses on bandwidth
The DNV-CP-0338 scheme is a foundational document referenced by many other specialized class programs. Products covered under this framework include:
Typical values per DNV-CP-0338:
Current density is the amount of cathodic current required per unit area of bare steel (A/m²). DNV-CP-0338 provides tables based on:
