Layers of Protection Analysis (LOPA) is a semi quantitative method of risk assessment analyzing the frequency of occurrence of events that can produce a hazard associated with handling of hazardous chemicals. To ensure safety, a LOPA considers the applicability of safeguards, the potential for individual layers of protection to fail, and the potential consequences that are consistent with the organization's risk tolerance Acronyms & Terms Glossary <- More Definitions What is LOPA in safety Layers of Protection Analysis (LOPA) is a semi quantitative method of risk assessment analyzing the frequency of occurrence of events that can produce a hazard associated with handling of hazardous chemicals.

Dormant or standby operation where the IPL takes action only when a process demand occurs and is otherwise inactive. Low demand mode occurs when the process demand frequency (i.e., when the IPL is challenged) is less than once per year. Low demand mode of an IPL is considered during Process Hazard Analyses (PHAs) conducted by aeSolutions' trained facilitators. PHAs help companies identify hazard scenarios that could lead to a release of highly hazardous chemicals that can cause negative impact on people, the environment, and property.

A Quantitative Risk Assessment is a systematic approach to determining the likelihood and consequences of hazardous events and expressing the results quantitatively as risk to personnel, the site being studied, the overall environment, and/or a company. Risk is a function of consequence and likelihood and aeSolutions has the experience and tools to evaluate both for a QRA. A QRA is a specialized approach to assess high consequence LOPA scenarios with large risk gaps to close. Further "pencil-sharpening" in the QRA will verify the severity of the scenario through consequence modeling, as well as the frequency of the scenario through fault tree modelling. Often conservative assumptions made in LOPA are revealed in QRA, which makes the solution to gap closure more practical. QRA will handle conditional dependence among IPL(s) and the initiating cause(s). aeSolutions utilizes commercially available software tools, along with in-house expertise, to facilitate QRAs. For example we can use the PHAST and SAFETI software to model chemical releases in evaluating consequences of an incident. QRA can be a valuable decision support tool when evaluating complex hazard scenarios.

A structured approach used to identify potential human failure events and to systematically estimate the probability of those events using data, models, or expert judgment. Human Factor Analyses provide qualitative insight to the human factors issues related to the error, and also provide a more accurate quantitative assessment than is found in standard LOPA tables for human performance credits. The ability to model conditional dependence among operator tasks, as well as model potential human recovery factors from errors, makes the HRA a valuable tool. For a typical HRA, a standard operating procedure (SOP) is broken down into discrete tasks. Interviews with Operations are conducted, known as a ""talk-through,"" as well as a plant ""walk-through"" which covers the equipment of concern from the SOP. PSFs (Performance Shaping Factors) related to each task are discovered. Dependencies among tasks are estimated. Each of these will influence the HEP (Human Error Probability) for each task. Each task is to be modelled as a success or failure. An HRA Event Tree is constructed, each identified task being a branch in the tree, and then solved; the output of which is typically an input to a QRA. aeSolutions has the Human Factors Reliability Experts to handle this task.

Intrinsic Safety is an equipment design approach that reduces the available energy to a level where it is too low to cause ignition. This is done for equipment that will be placed in particularly hazardous areas for the purpose to keep all temperatures low and to prevent sparks that could cause fires or explosions.

Specialty Chemical Site’s Increasingly Complicated Cutover When a project that began with standard safety system upgrades quickly expanded to a much broader scope of engineering with tight deadlines, aeSolutions responded with an experienced engineering workforce to deliver above-quality expectations while meeting key deadlines. Challenge The initial project scope included providing the client with instrumentation specifications and wiring and cutover plans to facilitate the cutover to a new system. Due to incomplete and outdated instrument lists, a significant and unexpected change in scope became required to include instrument specification services, which nearly doubled the time and manpower needed to reach the goal by the client’s deadline. Solution aeSolutions efficiently identified and conveyed the necessary adjustments to the project with clear and concise communication, enabling the client to swiftly make informed decisions, modify the scope, and adjust staffing accordingly. Our team quickly deployed resources to provide the following deliverables within the original schedule: • Instrument Specifications • Instrument Field Wiring • Cutover Mapping • Cutover Wiring In addition, aeSolutions designed custom cabinets for the cutover at the request of the client once it became apparent that the field loops would be doubled. During construction, aeSolutions assisted the client with locating and providing quality drawings for cutover installation and commissioning. Results Upon completion, the clients informed aeSolutions that the provided support was indispensable for a smooth start-up, and the subcontractors confirmed that aeSolutions specifically contributed to one of the most efficient cutovers they’ve ever commissioned. The client had large projects going on, and aeSolutions was able to save them costs by hitting their shutdown dates and not requiring additional shutdown time.
