aeShield Lifecycle-Enabled PHA/LOPA Engine

The cornerstone of a sustainable functional safety program is an accurate Process Hazard Analysis (PHA) and Layer of Protection Analysis (LOPA). aeShield® has a dynamic PHA/LOPA engine that supports risk assessment requirements of OSHA 1910.119 and fully integrates into the process safety lifecycle defined by ISA-84/IEC 61511. Additional benefits include:

  • PHA/LOPA Tightly Integrated
  • Bad Actor Identification
  • Cause or Consequence Based
  • Flexible Library Settings
  • Recommendation Tracking
  • Cause Summing
  • Revision Control
  • Data Migration Tools
  • Multiple Risk Matrices
  • Complete Reporting
  • Gap Assignments
  • Configurable Checklists

aeShield Quick Start Library

With over 20 years of process safety lifecycle consulting experience, aeSolutions has developed an extensive library to help companies hit the ground running with aeShield®. The library supports the entire lifecycle and includes templates for Safety Integrity Level (SIL) Calculations, Safety Requirements Specification (SRS), and functional test plans. Using the aeShield® Quick Start Library as a springboard for development of your own project, site or even corporate library, users can quickly and efficiently begin executing work. This results in significant savings of both time and money compared to building it from scratch.

aeShield Consolidated Toolkit

Many different disciplines need to be on the same page in order to capture the essence of functional safety standards. Process safety staff create the foundation, instrument and controls engineers build the safety systems, and operations and maintenance personnel maintain it. They are all using there own tools, and many times, these tools are not synchronized such that a maintenance technician or operator understands the risk associated with an individual device. By having a data model connecting risk rankings to tagnames, common activities no longer require the same amount of manpower to keep up with.

aeShield SIL Calculation Engine

Design SIFs quickly and easily with aeShield®. When aeShield is coupled with our Quick Start Library™, you can hit the ground running with a generic set of equipment definitions including failure rate data. Additionally, common SIF templates are provided for immediate instantiation making SIL calculations simple. 

aeShield Gap Assignment Module

Once you complete a Process Hazard Analysis (PHA) and its associated Layer of Protection Analysis (LOPA) for your facility, you have a list of gaps, LOPA recommendations, and perhaps legacy PHA/HAZOP recommendations. This list can add to the myriad of compliance-driven requests for capital versus ROI-based requests. Use the Gap Assignment Module to provide LOPA gap tracking, review associated costs, and quickly make business decisions on prioritization of risk-reduction related projects.

aeShield Maintenance Support

We know aeShield® can be the single-source of truth for your process safety data. The inherited data model linking risk rankings down to tagged devices makes it easier to support daily maintenance activities. Did you know you can also interface with maintenance management system (CMMS) data to gather test results and monitor on-time testing? As results are brought into aeShield, you can perform on-demand safety integrity level (SIL) calculations as your test interval increases and have line-of-site into upcoming critical tests. This information leads to better business decisions surrounding outages, overhauls, turnarounds and risk management.

aeShield Operational Leading Indicators

We know aeShield® can be the single-source of truth for your process data. The inherited data model linking risk rankings down to tagged devices makes it easier to support daily operations. Did you know you can also interface with process historian-type data to gather event data for further analysis?Regardless of the safety instrumented system (SIS), basis process control system (BPCS), or historian manufacturer/provider, you can create the rules to add process safety context to event data. Once the events are brought into aeShield, your subject matter experts can validate and further annotate to add even more value to the information. Operational data is the key to converting a reactive culture to a proactive culture. Use aeShield to unlock the information required for leading indicators to identify and take action against bad actors.

aeShield Data Conversion

aeSolutions has an implementation process to convert existing critical process safety information into our safety lifecycle management software. We recognize the historical spend creating the existing documentation; therefore, we focus on retaining its value in the most cost effective manner. Our process, tooling, and people ensure minimized cost regardless of types and formats of existing data. Let us help make your implementation efficient and effective.
