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.
Don't have up to date drawings, or worse, no drawings at all? Our personnel are able to head to your site with blank paper and deliver a PHA ready drawing package. With our field experience we are able to produce quality drawings and quickly identify safety concerns that could be rectified easily or just can't wait. While we're at site, we're also able to produce a 3D walk through tour to enable all office based stakeholders to experience the physical layout.
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 be brought in to analyze your plant to help with your next plant upgrade or controls optimization project.
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.
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.
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 high 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 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.
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.
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.
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.
