Understanding NACE SP0198: The Standard for Corrosion Control of Offshore Steel Pipelines

NACE SP0198 (formally titled Standard Practice Control of Corrosion on Steel, Fixed Offshore Structures Associated with Petroleum Production) is a crucial industry document published by NACE International (now part of AMPP: The Association for Materials Protection and Performance).

The NACE SP0198 standard, titled "Control of Corrosion under Thermal Insulation and Fireproofing Materials—A Systems Approach", is the definitive industry guide for mitigating Corrosion Under Insulation (CUI). Originally approved in 1998 as RP0198 and most recently revised in July 2017, this standard practice provides a comprehensive framework for protecting equipment in the chemical process, refining, and power generation industries.

Step 2: Prioritize Inspection Zones

Use the standard’s Table 1 (Risk Assessment Matrix) – reproduced in many training guides – to categorize assets as Low, Moderate, or High Risk. nace sp0198 pdf

First issued in 1998 (hence the "98" in SP0198), the standard has been revised several times, with the latest version being NACE SP0198-2017. It provides a systematic, risk-based approach to mitigating CUI across the entire lifecycle of a facility—from design and construction to operation, inspection, and repair.
