Fault-tree Analysis

Easy to use environment for developing complex system reliability models through an inexpensive and easy to use interface taking the pain out of building and managing fault-tree models and integrating with our SIS Lifecycle Management software and SIL Verification.

  • Quickly Identify Vulnerabilities in the System Design
  • Instrumentation & Control Equipment Failure Rate Database
  • SIS Lifecycle Management Integration for Complex SIL Verification Calculations
  • Part of the Kenexis Integrated Safety Suite

Quickly Identify Vulnerabilities in the System Design

Robust minimum cut set analysis reporting makes it easy for users to quickly identify vulnerabilities in the system design by viewing details of the minimum cut set analysis through a clear and interactive interface.  Provides valuable statistical analysis of the system highlighting the details of most significant combinations of events which could result in system failure which streamlines the process of sensitivity analysis and evaluation of alternative designs.

Instrumentation & Control Equipment Failure Rate Database

Kenexis extensive database of failure rate data for instrumentation and controls equipment comes with Arbor at no additional cost.  Failure data is quickly found, processed and applied in fault tree analysis within a matter a few simple mouse clicks, eliminating the time-consuming task of developing failure rate models for your fault trees.  Our engineers use this data every day to perform a variety of process safety studies so you can be sure that the data have been well vetted and is always current.

SIS Lifecycle Management Integration for Complex SIL Verification Calculations

Arbor is integrated with Vertigo™ SIS Lifecycle Management software to facilitate complex SIL Verification calculations.  By default, Vertigo will perform SIL Verification Calculations in conformance with the recommended practice of ISA TR84.00.02 Safety Instrumented Functions (SIF) – Safety Integrity Level (SIL Evaluation Techniques Part 2: Determining the SIL of a SIF via Simplified Equations).  For complex systems, this recommended practice is not sufficient.  Integration of the Arbor Fault Tree Analysis application allows an SIS designer to quickly and easily verify system designs regardless of the complexity of the system failure modes.  Fault-tree results from Arbor are easily linked to Safety Instrumented Functions in Vertigo for reporting purposes.

Integrated Safety Suite

Kenexis Software runs on our secure cloud servers and is accessed by any licensed user on any computer or tablet through a standard browser. The unique architecture ensures that your software is always available and up to date with the latest performance metrics and resource databases.

Our Process Safety Training Center is also integrated with the software on the Integrated Safety Suite so you can learn how to use the software, learn theory, and process safety engineering all in one place.

Our solution makes it easy for a licensed user to share project information with others including contracts, EPCs, and to leverage Kenexis process safety engineers for project assistance, outsourcing, and verification and certification of your analyses.

  • Compatibility with most browsers in most operating systems
  • Training Center is part of the Integrated Safety Suite
  • Extensive standard and custom equipment databases
  • Detailed technical documentation and help
  • Dedicated help desk and support

Training

In addition to the Support page, there are several training courses on our Integrated Safety Suite. You can request trial license above to gain access to the training.

Once you have access to the trial and Log In, you will find a “Training” button to access the classes.

The software classes above are no charge.

There are also theory and practice classes that require an annual training subscription. Click on Training to learn more about all the online training available.

Trial Request & Pricing

Price

Arbor is a cloud-based fault-tree analysis tool that includes access to Kenexis extensive database of failure rate data for instrumentation and controls equipment as part of the Integrated Safety Suite. A concurrent-user license cost $1,250/year. One concurrent license can be used easily in small team, but if you start needing access more when someone else is using the one license, you can add additional licenses at a discount annual subscription rate.
