The proposed solution involved the digitalization of the risk analysis process in the industrial plant. For this, the related documents were centralized in Vidya’s platform and visual simulations of the intervention process in the industry were created to understand the necessary sequencing of actions and optimize decision making.
The first step of the deployment was to treat and upload the 3D model of the assets involved in the project into the Vidya platform.
In this step, our engineering team processed and contextualized all existing information related to safety procedures, such as HAZOP and PRA, and engineering documents, like TAGlines, engineering drawings and component technical specifications. This task employs Optical Character Recognition (OCR), a technology used to extract information from documents, create shortcuts and link them into the respective assets.
From this, it was possible to link the documents to the 3D modeling with VFiles technology and organize them in folders of their respective components, enabling the access and visualization of this information with a few clicks.
After contextualizing the data and separating the different procedures into their components, it was possible to feed the Scenarios feature into the Vidya system. This feature consists in a visualization and animation tool capable of demonstrating events and their consequences, right in the 3D model.
These events can be a risk, a sequence of actions, process triggers, sequence of physical processes, sequence of system processes, single operational stop procedures, anomalies or failures, that were previously mapped (in the engineering documents, HAZOP and PRA), and the actions needed to prevent or remediate these situations. Here is an example:
”On a specific tagged piping, if a gas leak happens, the engineer will smell a strong gas odor and at the same time should proceed to close a specific valve connected to the piping in question, and this will affect another near equipment (…)”
In this project, it was also possible to map and highlight critical elements, which are a list of Operational Safety (OS) equipment that in case of failure can cause critical or catastrophic accidents, such as pressure safety valves (PSV). By running the sequencing of actions in the platform, it was possible to visually distinguish these components with different colors, to understand the most important ones in each process, and also create filters to identify and isolate them in the 3D model.
Finally, to make the risk analysis more complete, Entities were added to the system. An entity can represent things that weren’t able to be represented through 3D components itselfs, just as smell, sound, hazards (like danger of falling things), isolated areas, or zones.
These entities are visible in the 3D model, in the configured perimeter area, and complement the existing scenarios, as the one exemplified above.
