Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Safety Instrumented Functions (SIFs) in processing plants may fail to adequately reduce the likelihood of hazardous events, such as explosions or injuries, due to failures or manual bypasses, leading to inadequate protection against process risks like vessel rupture and hydrocarbon releases.
Innovation Solution
An Operations Safety Advisor (OSA) system provides a computer-implemented method for generating and displaying a process safety risk matrix, using a 2-dimensional representation of risk cells with likelihood and severity levels, and visualizing real-time changes in risk, enabling improved scoring and corrective action recommendations to enhance process safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional safety monitoring methods are used, then system complexity is kept low, but real-time risk visualization and quick reaction to safety incidents are insufficient
Solution Approach 1:
The patent introduces a visual dimension to safety monitoring through the risk matrix display, transforming abstract safety data into spatially organized visual representations. Different risk levels are mapped to different matrix cells, enabling operators to quickly grasp safety status at a glance. This dimensional transformation enhances ease of operation without fundamentally increasing system complexity.
Solution Approach 2:
The system creates visual copies of safety data through the risk matrix representation, where each cell is a simplified copy containing key information about hazard likelihood and severity. These visual copies enable rapid information processing and decision-making without requiring complex analytical operations, thus improving ease of operation while maintaining manageable system complexity.
2Measurement precision
If detailed safety risk assessment is performed, then safety management quality is improved, but response time to safety incidents may be delayed
Solution Approach 1:
The system performs preliminary classification of safety risks by organizing potential hazards into predefined risk matrix cells with specific likelihood and severity criteria. This preliminary organization enables rapid identification and response to actual incidents, as they can be immediately categorized and matched to appropriate response protocols without requiring detailed analysis at the moment of occurrence.
Solution Approach 2:
The risk matrix display dynamically updates in real-time based on incoming safety data, automatically adjusting the visual representation of risk levels. This dynamic adaptation allows the system to maintain high measurement precision for safety assessment while ensuring immediate visual feedback and rapid response capability, eliminating the trade-off between accuracy and speed.
