Thousands have switched worldwide because this software solves complicated problems.
Deliberately Different
First, our software was created from the beginning to be a comprehensive, cloud-based software product. However, the need for a local desktop version to facilitate HAZOP and LOPA workshops in remote locations with limited internet access was known from the beginning, so we used the same code to create a desktop version. The two versions work well together for our customers. Then we did something other software vendors would never consider, we gave away the desktop version at no charge.
Second, other PHA software vendors created software that also record studies but the information is saved in a format that was restrictive and difficult to integrate with other software tools. Open-PHA™ was built with a super-set data structure so that the information recorded can be accessed by virtually any other software tool. Designed with integration capability from the beginning makes it easy to build dashboards for critical safety study data and enable word processing software to create custom report using defined wildcards like <%Lopa_Recommendations%>.
Third, no one likes software revisions and fees to upgrade so we built Open-PHA™ Cloud and Open-PHA™ Desktop to automatically keep up to date at no charge. Open-PHA™ Cloud is an annual subscription license; however, any revisions or upgrades are included as part of the license.
Finally, we built Open-PHA™ knowing you may want to use the data in other applications. Our software does not lock up your study data in a proprietary, unusable format. In fact, your study data can easily be exported from Open-PHA™.

Features
Open-PHA™ Cloud and Open-PHA™ Desktop are designed for documenting, analyzing, and maintaining Process Hazards Analysis studies such as HAZOP and LOPA.
Open-PHA™ Desktop is a complete PHA software package and is free to download and use on a Windows, Mac, and Linux computer.
Open-PHA™ Cloud is enhanced using internet-based computing. Added features enhance the software and provide access to the other software tools from Kenexis like synchronizing IPFs (an IPF can be a SIF, EPF, MPF, F&G, BPCS, PSV) from Open-PHA™ Cloud with our other software to perform SIL Verification or Fault-tree Analysis.
Both products support customized Templates, Reporting, Risk Matrix, Likelihood Categories, Consequence Categories, Risk Rankings, Nodes, Deviations, HAZOP & LOPA Worksheets, Recommendations, Safeguards, a Parking Lot, and Checklist.
Open-PHA™ Desktop stores files locally on your computer without the need for an internet connection to facilitate work in remote areas. In many cases, this is enough for the small shop or contractor working on a budget. If at some point in the future you want to upgrade to the cloud version, the process is easy and now you can take advantage of the cloud-based storage provided from Open-PHA™ Cloud.
Cloud-based Kenexis software products provide advanced features including secure storage and sharing, and integration with other software Kenexis software. The storage and sharing provide much more than just a file storage system. Our secure cloud-based platform is used to share secure and controllable access for editing or viewing files at a site, with corporate, and even with third parties. Now instead of emailing files and losing version control, everyone throughout the lifecycle can interact with one set of files securely and completely under your control. This is significant when files need to be shared especially outside of your organization with a contract engineering firm.
Open-PHA™ data structure design is fully integrated using an open-source JSON standardized data structure that is revolutionizing PHA documentation. This structure allows the development of tools that can display a single set of data as a HAZOP worksheet, LOPA worksheet, or Bow-tie diagram. Gone are the days of porting and manipulating data and worrying about the consistency of information across multiple files, studies, or data structures. This allows the data from multiple scenarios to be rolled up into easier to use hazard registers and visualized with graphical approaches like bow-tie diagrams, eliminating the frustration of managing replicated data in multiple locations and different languages.
Open-PHA™ supports both explicit and the less common implicit LOPA. In an Explicit LOPA, the team establishes a TMEL target based on a consequence severity, then explicitly defined frequencies of cause, and applies frequency modifiers such as conditional modifiers, enabling events and probabilities of failure for IPL’s. In an implicit LOPA, the team works with the concept of “LOPA credits”.

Migrating PHA Studies to Open-PHA™
We realize you have PHA studies on other software including spreadsheets and transitioning to secure cloud-based solutions may seem difficult and time consuming. Let us make that easy for you. We will create the merge tool and port your PHA studies into Open-PHA™ and then you can take advantage of our unified hazard assessment data structure to perform SIL Verification, Fault-tree Analysis, Quantitative Bowtie Analysis, and SIS Life Cycle Management.
Because HAZOP and LOPA studies are the core of process safety documentation, we believe it is important for the information contained within the HAZOP and LOPA to be easily shared across common applications and platforms. Open-PHA™ was developed to make it easy to pull data from HAZOP and LOPA studies into custom software tools for broad analysis and custom reporting. This philosophy is a paradigm shift in PHA software as file data structures have historically been proprietary to prevent third-party access and discourage the use of competing software tools.
We will help you transition from your existing PHA software to Open-PHA™ software and provide training to make the transition easy.

Open-PHA™ Cloud – Pricing
Open-PHA™ Cloud runs in a browser to take advantage of additional cloud-based computing functions to add capabilities that enhance HAZOP and LOPA studies performed in Open-PHA™ Desktop. A concurrent-user license currently costs $1,250/year; however, this will increase to $2,250/year on 01/01/2024. Anyone with a license prior to 01/01/24 will enjoy “Legacy” pricing. The Legacy pricing will remain at the current rate of $1250/year with nominal annual operating cost adjustments related to increased costs starting 01/01/25. This includes any new, additional licenses purchased after 01/01/24.
One concurrent license can be used easily in a 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.
