Capital Project Execution Case Study
This capital project execution case study describes how a major integrated energy company evaluated a digital approach to functional safety across HAZOP, LOPA, SIL assessment and SIF design.
The client compared its current work processes and technologies with an integrated safety lifecycle tool as part of its move toward digitalization. The figures and testimonial below come from the original case study.
The Digital Approach to Capital Project Execution
There are several areas where capital project execution has failed to modernize and take advantage of technology in the areas of HAZOP, LOPA, SIL Assessment, and SIL Design.
Traditional, stand-alone tools are independent, rely on manual data transfer, and are managed across multiple engineering disciplines. Current tools have become costly to maintain and may no longer be competitive compared to similar commercial off-the-shelf tools.
Objective: An Integrated Safety Lifecycle
The client decided to evaluate continuing to use its current work process and technologies versus planning for their eventual retirement by moving deliberately and strategically toward a fully integrated safety lifecycle tool in accordance with its quest for digitalization.
The expected outcome was greater efficiency in managing capital project execution activities in compliance with IEC 61511 full safety lifecycle requirements through nonproprietary commercial off-the-shelf software.
For standards context, IEC 61511-1 describes requirements for the specification, design, installation, operation and maintenance of a safety instrumented system.
Capital Project Execution Challenges
Limited access to relevant evergreen data.
Poor data quality assurance practices.
Limited visibility via reliable reporting.
Focus: HAZOP, LOPA and SIF Design
HAZOP study execution and importing.
LOPA rationalization.
SIF design and verification.
Capital Project Execution Results at a Glance
3K man-hours saved during engineered design.
50% earlier SIF design resolution.
32% less time to complete the SRS.
74% reduction in functional safety man-hours.
Major Integrated Energy Company Testimonial
“As a firm believer in the data centric approach, I became increasingly frustrated with the way we were managing our functional safety process due to the multiple tools, databases, and spreadsheets we had to manage. After searching for Data Centric Functional Safety, I ran across Mangan Software’s Safely Lifecycle Manager, an application that carries functional safety all the way from the HAZOP through SIF Design and through Run and Maintain. After a lengthy evaluation process, we opted to run a Pilot with Mangan SLM on our newest project. SLM did not disappoint, as we saved thousands of manhours and months of schedule due to increased efficiency, and the elimination of manual data transfer between tools. We are now using SLM on all our Deepwater projects in the GoM.”
— Chad Clement, Process, Instrumentation, Controls & Electrical Engineering (ICE) Team Lead
Driving Towards a Standardized Enterprise-Wide Digital Transformation
The evaluation connected project execution with a standardized, enterprise-wide approach to functional safety information.
Benefits Realized Through Data Management
Streamlined data entry and data transfer.
Efficient LOPA rationalization, such as copying or cloning LOPA scenarios, allowed for efficient use of engineering time.
Specific task lists provided a standardized approach to the verification process.
Increased design accuracy led to a reduction in rework.
Quality Assurance and Progress Monitoring
Developed progress reports for monitoring and resource planning.
Access to Data and Collaboration
A collaborative work process shared information cleanly across multiple departments, making process safety data available for immediate use by all parties.

Capital Project Execution Results
An executive summary by the organization’s Senior SIS Focal Point and Senior Instrumentation/Manufacturing SME concluded that SLM was a viable, fit-for-purpose replacement for several stand-alone software tools currently used for analysis and design activities, providing the desired integrated approach to data management across the entire safety lifecycle.
SLM made process safety data available immediately, eliminating manual data transfer from one application to another for LOPA, SIF Design, SIL Validation, and the associated rework typically required for updates to the HAZOP/LOPA. Deliverables were completed ahead of schedule and under budget.
By consolidating critical process safety information platforms and work processes, engineering, operations and leadership can make quicker, informed decisions, shifting the organization to a more data-centric approach.
The client ultimately executed a Global Enterprise Agreement that enables it to deploy SLM across its integrated upstream, downstream and midstream lines of business.
