UNDIP – In the shipyard industry, the availability of components or materials often becomes a critical factor influencing the smooth progress of ship construction. Based on previous research, the probability of delays in shipbuilding tends to be high due to challenges in procuring materials or components. Addressing this issue, Dr. Zulfaidah Ariany, S.T., M.T., a lecturer in Naval Construction Engineering Technology (Teknologi Rekayasa Konstruksi Perkapalan / TRKP) at the Vocational School of Universitas Diponegoro, has developed an innovative risk assessment model that integrates the Failure Mode and Effect Analysis (FMEA) method with Value at Risk (VaR).
Dr. Zulfaidah Ariany, who also serves as the Secretary of the D4 Naval Construction Engineering Technology Study Program at the Vocational School of UNDIP, stated that this model is designed to enhance risk management during the ferry construction process in Indonesian shipyards. Through this approach, potential risks can be identified and measured more accurately to minimize project disruptions.
To address these challenges in the shipyard industry, the study combines the following:
- FMEA: Identifying potential failures by evaluating severity, occurrence, and detection scores to determine risk levels.
- Value at Risk (VaR): Using occurrence scores from FMEA as a basis to analyze and calculate failure probabilities more accurately through a Bayesian probabilistic approach.
Dr. Zulfaidah involved several ferry shipyards using surveys and questionnaires to identify a list of potential failures and risk sources in shipbuilding. This data was then used to create a risk assessment model tailored to industry standards. The assessment proceeded with the use of a risk matrix and the application of value at risk, which was capable of calculating detailed failure probability rankings.
The model is also equipped with risk mitigation measures based on risk assessment standards for ferry construction projects. “The research findings provide an evaluation of risk levels in the categories of hull materials, machinery, electrical systems, and other equipment, offering solutions in the form of a component availability model application to aid in monitoring and managing 600 GT ferry projects,” Zulfaidah explained.
“The assessment results are expected to help shipyards better understand and manage project risks,” she continued.
“This model development not only provides a comprehensive overview of risk levels but also presents effective ways to improve project management efficiency. The application derived from this model is expected to become a strategic tool for shipyards to prevent delays and maximize production outcomes,” Zulfaidah elaborated.
This research marks a significant contribution to the development of Naval Systems Engineering knowledge and the competitiveness of the national shipbuilding industry. As the Secretary of the D4 Naval Construction Engineering Technology Program at the Vocational School of UNDIP, Dr. Zulfaidah remains committed to supporting the development of technological innovations in the maritime sector.
