Process Hazard Analysis (PHA)
Our Functional Safety Engineers facilitate Process Hazard Analysis using a number of methodologies including HAZOP, What-If, HAZID, and Checklist. Our engineering and field experience make our approach both personable and practical. Ask us for details on how we can help you to reduce the overall HAZOP session time while improving the quality of the risk assessment. Our facilitators are all senior level bringing extensive experience to your review.
P&ID As-building
In need of HAZOP quality P&ID's? Do you wish to ensure HAZOP relevant data is captured avoiding recommendations to confirm information that should already be available. Our senior level as-built team can deliver a PHA ready drawing package quickly and accurately. With our strong background in instrumentation and controls and and eye for risk, we are able to collect all the necessary data and identify safety concerns that just can't wait for HAZOP. While onsite, we're also able to collect 360 ° images and drone footage for reference in HAZOP. We can even produce a 3D walk through tour to enable remote stakeholders to experience the physical layout.
Understanding Your Control Systems
Our controls background enables us to generate shutdown keys and control narratives that are easy to follow and PHA ready. Whether you have a new system, existing system with legacy documentation or worse no documentation at all, we can analyze your plant to help with your next upgrade.
With our automation and facilitation backgrounds, we are the supplier of choice for your CHAZOP facilitation needs. Our CHAZOP approach identifies ways in which plant operability and availability can be improved while enhancing the performance of safety systems and cybersecurity tools.
SIL Assessment / Determination - Layer of Protection Analysis (LOPA)
Our facilitators are highly skilled in safety integrity level (SIL) assessment. Using advanced safeguarding expertise, in many cases we can guide the team to solutions that avoid the need for a safety instrumented function (SIF). When a SIF is determined to be the best available safeguarding option, we can help to provide solutions that are reliable, practical and maintainable. The efficiencies gained by using our facilitators for both HAZOP and LOPA will save both time and money on your projects.
Quantitative Risk Assessment (QRA)
Many industrial facilities have some equipment that presents significant risk to personnel or the public. LOPA may not be the best risk assessment technique for high complexity or very high risk scenarios. Rather than accepting unreasonably high SIL targets, consider a Quantitative Risk Analysis (QRA) as an option for some of the highest risk and complexity scenarios. This analysis requires a higher level of engineering effort but enables the analyst to remove some of the conservatism inherent to less quantitative techniques such as LOPA.
SIL Verification Calculations
SIL verification calculations are performed to verify a proposed design meets the safety integrity target identified in a SIL assessment. Watchmen can perform these calculations quickly and accurately presenting options that can minimize the need for additional hardware or redundancy and maximizing proof test interval. A strong understanding of this technique can often save money stemming from over designing. Under designing can leave you lacking protection.
Safety Requirement Specification
A comprehensive Safety Requirement Specification (SRS) is a key document used to ensure all SIF's are designed, installed, maintained and tested properly to ensure they provide the needed safety integrity. Watchmen can provide detailed and comprehensive SRS packages quickly and effectively using our proprietary SRS tools.
Instrument Proof Test Procedure Development
Performing an effective proof test is critical to maximizing SIL performance and extending the test interval. Watchmen can develop comprehensive test procedures that will maximize proof test coverage. Our easy to use checklists and procedures will help you to document the regular testing being performed and take action if there are any failures.
Functional Safety Assessment (FSA)
A functional safety assessment is an audit performed to ensure lifecycle activities have been properly performed and that safety functions will be operated and maintained to achieve the designed integrity. There are many activities required to ensure proper implementation of a safety system, and many ways this can go wrong. Watchmen can perform this audit and provide peace of mind by ensuring nothing slips through the cracks.
Regular SIS Audits
Regular SIS audits are a necessary for compliance with IEC 61511 and to ensure the SIS achieves the intended reliability. These audits will ensure lifecycle activities are in place and being followed. Audits are an opportunity to identify process gaps before they result in unwanted failures.
The Watchmen Advantage
Our Specialists bring depth of knowledge to your HAZOP or SIS project and can support the entire SIS lifecycle. No need for multiple vendors that only offer one piece of the puzzle. With our support, each deliverable is documented for use by the next downstream activity. Nothing is lost in interpretation. No learning curve is required to get up to speed with where the previous team left off.
We also offer to as-built your P&ID's documenting all necessary information for HAZOP, and then leverage our knowledge of your facility in HAZOP. Imagine the efficiency gained when your facilitator is already familiar with your facility, site conditions, met the operators, has a library of photos to draw upon and has already identified potential recommendations for the HAZOP team to consider.
