What Our Clients Say

“The folks at ioMosaic are always pleasant to work with and take care of our requests quickly.”
“I appreciated the quick turn around on requests for changes made during the testing phase for three new PSE modules we wanted.”
“We recently added three new modules to PSE to replace paper processes for Personnel MOCs, New Chemical Approval, and Variances) in the plant. It will now be so much easier to use these three new modules instead of trying to keep track of paper copies.”
“Customer service is excellent! Working with Tao to help solve problems and teach me how to use the system to it's fullest has been a wonderful experience.”
“The customizable aspect of PSE program makes it easy to have multiple risk assessments/approvals at the beginning of the MOC lifecycle.”
“PSE has made auditing the MOC system much faster. Since it is customizable, it also makes it a lot easier to meet our needs and comply with OSHA PSM. It makes the MOC approval process so much faster than paper.”
“Before PSE, our MOC communication was a lot slower and much more cumbersome with a paper system.”
“We chose PSE as cost was a factor; it was less than some of the other options we reviewed. Also, the ability to format the workflows to incorporate our existing procedures and practices met the needs of our facility PSM program.”
“The new cloud-based hosting service from ioMosaic has improved our overall operating speed as well as provided a much quicker response. Prior to cloud-based service, our IT staff had to take time to coordinate updates.”
“We have no other providers who respond and resolve issues as quickly as the team supporting our PSE system. The support is second to none and is greatly appreciated.”
“Prior to utilizing PSE we had a manual paper process for our MOCs and PSSRs. This required a significant amount of time for routing and walking paperwork around. The ability to streamline MOC and PSSR forms electronically significantly reduced our workload.”

Maximize Use of your Existing Flare Structures

Consequences of Overpressure

Existing pressure relief and flare systems may be overloaded because of prior unit expansions / upgrades have increased the load on the flare for combined flaring scenarios beyond the original design intentions. This paper provides a general framework for evaluating and maximizing available flare systems capacity, and investigates criteria and approaches for determining a tolerable risk event for flare systems.

Featured Case Studies


Relief Systems Audit Case Study

A large refinery desired to conduct a third-party audit of their emergency relief systems to ensure that the methodology and engineering analysis used in the design of their emergency relief systems was adequate, conformed to RAGAGEP, and was being performed consistently without significant systemic errors. The audit scope covered two units within the refinery, and considered both individual relief devices, and entire flare systems.

View Case Study
A multinational energy company wanted to complete an evaluation of a pressure relief valve system in order to comply with the PSM standard OSHA 29 CFR 1910.119 which requires that employers compile information pertaining to the equipment in the process, including relief system design and design basis. 
An LNG manufacturer had four nearly identical trains with three flare header systems. The client decided they wanted to use a new and more stringent criteria than previously performed under a different design criterion. The large scope and tedious nature of the data entry was a challenge since all calculations needed to be checked to determine the maximum pressure each flare pipe line would be exposed to.
A leading producer of chemicals and related products needed an evaluation of their Light Olefins Unit to ensure compliance with the OSHA 29 CFR 1910.119 PSM standard.

Minimize the Impact of Change

Management of Change Workflow Can Help

Process Safety Enterprise® workflow guides users through a step-by-step process for standard MOC functions such as MOC initiation, approval, PHA revalidation, pre-startup safety review (PSSR), start-up authorization, etc. The action items are tracked and documented, and workers are notified via email with documentation linked, to make sure changes are properly captured.
