 Course Overview

API RP 581-2016 (3rd Edition) is the latest update on the Risk-based Inspection Methodology. This code provides (1) methods for developing an inspection plan for fixed equipment, including pressure vessels, piping, atmospheric storage tanks (AST), pressure relief devices (PRDs), and heat exchanger tube bundles; (2) quantitative methods for calculating the probability of failure (POF) for fixed equipment (the POF is based on the component type and damage mechanisms present based on the process fluid characteristics, design conditions, materials of construction, and the original construction code); (3) quantitative methods for computing the consequence of failure (COF). This 5-day course provides participants with a clear and thorough understanding of the quantitative procedures used to establish an inspection program using risk-based methods outlined in API 581. WebCorr’s API RP 580 course is a prerequisite to this API 581 course (API 580 introduces the principles and presents minimum general guidelines for RBI while API 581 provides quantitative calculation methods to determine an inspection plan).


This 5-day corrosion short course is available for in-house training, on-site training, online and distance learning worldwide. It can also be customized to meet the specific needs of your organization.

 In-House Training Corrosion Courses/On-Site Training Corrosion Courses


If you are concerned with corrosion in your business, in-house training or on-site training is a great solution to train a group of employees from design, production, operation, quality assurance, inspection and maintenance, and technical sales and support on corrosion control and corrosion prevention technology. The contents of all corrosion courses can be customized to fit your organization's needs.


There is no minimum or maximum number of participants required for in-house training corrosion courses. We conduct the in-house training corrosion course at your company's premises and at a time convenient to your company.

 Corrosion Course-On-Demand


All our publicly scheduled corrosion short courses are conducted once a year. However, you do not need to wait for one year if you have missed any of the publicly scheduled corrosion courses as we have this unique corrosion course-on-demand scheme: we will conduct the course just for you on an one-on-one basis at a time and a location convenient to you. This option costs significantly less than a full-scale in-house training program.

 Online and Distance Learning Corrosion Courses

All our corrosion short courses are available for online or offline distance learning. You can start an online course at any time and learn at your own comfortable pace, whenever and wherever you are. You have around-the-clock access to interactive and media-rich course materials, virtual labs, course instructions, course assignments, and course assessments. Discussions and questions related to the corrosion courses are posted on the website or exchanged through email for a period up to 3 months. Video conferencing or instant messaging can also be arranged for discussions of course topics. For those who do not have ready access to internet, we can send you our online course materials on a CD-ROM or DVD or USB memory stick for offline learning.

 PowerPoint Slides and Test Banks for Trainers, Instructors, Tutors, University Lecturers and Professors


If you are involved in teaching or training, you may wish to purchase a complete set of the trainer's package for this training course. The trainer's package comes complete with ready-to-use PowerPoint slides (fully editable) and test bank (with answer keys). These ready-to-use PowerPoint slides contain high quality color photographs, illustrations, animations, audio and video clips. The test bank contains questions conveniently grouped into four categories: (1) true or false, (2) multiple choice, (3) calculation, and (4) reasoning and open-ended discussions. The trainer's package is suitable for in-house training and university teaching (30 lecture hours). This is exactly the same package that WebCorr uses to deliver our current training course.

The one-time lump sum fee allows your organization to use the training package and also modify it. For example, your organization may modify the course contents and re-name/re-brand the course under your organization’s name. WebCorr only retains the copyright of the original PowerPoint slides and test banks.
