Risk Based Inspection Technologies

Our group Frontium Energy Sdn Bhd, with a strong partnership with Equity Engineering Group (E2G), is pleased to announce ourselves as the world’s leading provider of risk based inspection services and software. Many major and multinational cooperation have established this method in their filed with the help from E2G in terms of study, implementation and specialized training.

The API Risk-Based Inspection (API RBI) methodology is used to manage the overall risk of a plant by focusing inspection efforts on the process equipment with the highest risk. API RBI provides the basis for making informed decisions on inspection frequency, the extent of inspection, and the most suitable type of NDE. In most processing plants, a large percent of the total unit risk will be concentrated in a relatively small percent of the equipment items. These potential high-risk components may require greater attention, perhaps through a revised inspection plan. The cost of the increased inspection effort may sometimes be offset by reducing excessive inspection efforts in the areas identified as having lower risk.


The API RBI software, created by owner/users for owner/users, is based on API Publication 581, Base Resource Document – Risk-Based Inspection. Practical features are built into the technology, which is based on recognized and generally accepted good engineering practices. The purposes of a risk-based inspection program are summarized as follows:
  • Screen operating units within a plant to identify areas of high risk.
  • Estimate a risk value associated with the operation of each equipment item in a refinery or chemical process plant based on a consistent methodology.
  • Prioritize the equipment based on the measured risk.
  • Design an appropriate inspection program
  • Systematically manage the risks associated with equipment failures.
RBI defines the risk of operating pressurized process equipment as the combination of two separate elements: the consequence of failure and the likelihood of failure. Software features include:
  • Analysis for pressure vessels, tanks, piping and pressure relief devices.
  • Three levels of analysis from qualitative > semi-quantitative > quantitative.
  • Automated inspection planning.
  • Consequence values expressed in terms of risk per unit area, risk per unit area per year, financial risk, matrix cell location and provide the options to factor injury, equipment damage, downtime costs, and toxic, explosive, fire damage, environmental, effects into the analysis.
  • Consequence models for various fluids and gases commonly encountered in the refining, petrochemical and chemicals industries.
  • Discrete risk values for each piece of equipment.
  • Qualitative risk matrix rankings.
  • Financial risk calculation options.
  • Data transfer utility to speed up information entry.
  • Expert system damage module calculators for various specific corrosion mechanisms (localized and generalized), various specific cracking mechanisms, fatigue, creep, high temperature hydrogen attack, various embrittlement mechanisms, etc. These modules are based on recognized and generally accepted good engineering practices, i.e. the latest available.
  • Perform “What If” analyses to consider changes and new equipment/unit reviews.
  • Report capabilities for all risk scenarios, matrices, risk summaries, consequence and likelihood basis reports and inspection plans.
API RBI technology systematically factors risk into inspection decision-making, helping identify areas of vulnerability by confirming equipment condition, identifying damage mechanisms and rates, and predicting Probability of Failure. The outputs of a RBI study help plant personnel make more informed decisions and target inspection dollars where they are needed most.

Software licensees also have the privilege of participating in user group meetings with industry owner/user peers where participants share practical implementation experiences and establish the future evolution of the technology. Over 22 owner/user companies participate in the API RBI review and development process. Few other technologies can claim the high level of quality attained by subjecting the software to ongoing scrutiny by industry experts. This assures the best possible technology and features are available for practical, effective prioritization of inspection related resource allocation and risk management.

API RBI software users may rest assured that this innovative software program satisfies the requirements for RBI technology, as set forth in the latest editions of API Standards 510 and 570, and Recommended Practice 580, and allows the owner/user to establish inspection plans as an alternative to the traditional API 510 or API 570 approach. As a player in the Oil, Gas and Energy industry, our business activities is very focused and specialized in order to maintain the quality of services at all times. In addition to that, through the technical partnership with prominent and fortune global company, it has given significant value added to Frontium Energy to serve the clients with more vibrant and broader area of expertise. At Frontium Energy, we are dynamic, passionate and enthusiastic to discover novel efficient technologies and solutions to accommodate the industry needs. We believe that the needs of improvement and enhancement are a continuous and infinite journey. In this respect, we are frequently engaged with our clients to well understand the requirements and offer our consultancy services and technical expertise to achieve client’s goals without compromising quality standards.

Our long term plan is to establish a local center of expert in this ageing plant specializing on Pressure Relief Device and also to provide a platform of collaboration with education centre and authority body to create the awareness of new Technology and implementing the best practice to ensure the Safety, Compliance and Reliability to the Industry.
