02The enhanced risk evaluation facilitated by KBRAM can lead to reduced safety costs and more efficient decision-making.

Application

Design takeaway

How to apply

When assessing risks for a new product or system, explore the use of computational modelling that goes beyond simple checklists, incorporating expert knowledge and probabilistic reasoning to predict potential failure modes and their severity.

Project actions

01When researching a problem, look for existing models or frameworks that you can adapt or build upon.
02Consider how you can incorporate qualitative data or expert knowledge into your quantitative models.

Method & Evidence

AimTo develop and validate a knowledge-based risk assessment method (KBRAM) that improves decision-making for safety on offshore oil and gas platforms.

MethodDevelopment and validation of a novel risk assessment model.

ProcedureThe research involved a comprehensive literature review of risk analysis and safety management, followed by the development of a knowledge-based risk assessment method (KBRAM) that integrates fuzzy reasoning. Data was collected from the offshore oil and gas industry through surveys, site visits, interviews, and questionnaires to test and validate the KBRAM against traditional methods.

ContextOffshore oil and gas platforms

Variables

IVInclusion of a third parameter in the risk assessment model (KBRAM vs. TPRAM).

DVAccuracy and efficiency of risk level classification; facilitation of decision-making.

CVData collected from the industry; traditional fuzzy two-input parameter risk assessment method (TPRAM) as a baseline.

Strengths & Limitations

Strengths

+Development of a novel, integrated risk assessment framework.
+Empirical testing and validation using industry-specific data.

Limitations

The data used for model testing was specific to the offshore oil and gas industry and may not be directly transferable to other domains without adaptation.

Reliability & validity

The study reports preliminary validation, suggesting a need for further testing to establish robust reliability and validity across a wider range of scenarios and data sets.

Think critically

How might the 'knowledge-based' aspect of the KBRAM be subjective, and what steps could be taken to ensure the knowledge integrated is objective and universally applicable?

Design Principles

"For complex systems, leverage multi-parameter, knowledge-infused models to achieve more accurate and actionable risk assessments."

This research highlights the potential of advanced modelling techniques to move beyond traditional risk assessment methods. By incorporating more nuanced data and reasoning, designers and engineers can achieve more robust safety evaluations, leading to better resource allocation and reduced operational risks in high-stakes industries.

What This Means for Your Design

This study shows that using a smarter computer model that considers more information can help engineers make better and cheaper decisions about safety on oil rigs.
