Corrosion and metal degradation are inevitable phenomena in various industries, and using Standards that provide detailed assessment to evaluate the structural integrity of an in-service damaged component is absolutely essential. Among all existing Standards, API 579-1/ASME FFS-1 is a well-known assessment standard recognized as Fitness-For-Service (FFS) assessment and is employed in various industries to assess the structural integrity of in-service pressure vessels and storage tanks that may contain a flaw or damage. In this study, software for the FFS evaluation was developed according to Part 7 of the third edition of the AP1579-1/ASME FFS-1 and was written using C# programming language. This software is developed for low-strength ferritic steel pressurized components with hydrogen blistering (HB) damage, in order to facilitate decision making on run-repair-replace of an in-service damaged component.

Over time, industrial equipment, particularly in the oil, gas, and petrochemical industries, is subjected to various forms of degradation and damage that can affect its structural integrity. Most of the Codes and Standards pertaining to components do not address the issues of degradation and damage. As such, performing a Fitness For Service (FFS) assessment is recommended to make run-repair-replace decisions of an in-service component that may be flawed or damaged. In this study, FFS Master –Fitness For Service (FFS) evaluation software –was developed according to the 3rd Edition of the API579-1/ASME FFS-1. The software coding was written using C# programming language with SQL server database. This software is developed specifically for low strength ferritic steel pressurized components with hydrogen induced cracking (HIC), giving the user the ability to accurately assess if system components can continue to operate in their current service condition.
