In the shipbuilding industry, the availability of materials or components is often an essential factor affecting ship construction’s smoothness. Based on previous research, delays in the shipbuilding process frequently occur due to problems with the procurement of materials or components. To overcome this problem, Dr. Zulfaidah Ariany, S.T., M.T., Lecturer in Shipbuilding Construction Engineering Technology (TRKP) at the Vocational School of Diponegoro University (Undip), has developed a risk assessment model that combines the FMEA (Failure Mode and Effect Analysis) method with Value at Risk (VaR).
Dr. Zulfaidah, who also serves as Secretary of the TRKP D4 Study Program at the UNDIP Vocational School, explained that this model aims to improve risk management in the ferry shipbuilding process at Indonesian shipyards. With this approach, possible risks can be identified and measured more precisely to reduce disruptions in the project.
This study combines two main methods, namely:
- FMEA: Identifying potential failures by assessing severity, occurrence, and detection scores to determine the level of risk.
- Value at Risk (VaR): Using occurrence scores from FMEA to analyze and calculate the probability of failure with a Bayesian probabilistic approach.
Dr. Zulfaidah involved several ferry shipyards in this study with survey and questionnaire methods to identify potential failures and sources of risk in ship construction. The collected data was used to build a risk assessment model adjusted to industry standards. The assessment was continued by using a risk matrix and the application of VaR to calculate the probability of failure rating in more detail.
This model is also equipped with risk mitigation based on risk assessment standards in ferry construction projects. “The final results of the study provide an evaluation of the level of risk in the hull material group, engines, electrical systems, and other equipment, with a solution in the form of a component availability model application that helps supervise and manage the 600 GT ferry project,” said Zulfaidah.
“The results of this assessment are expected to help shipyards understand and manage project risks better,” he continued.
“The development of this model provides a comprehensive picture of the risk level and presents an effective way to improve project management efficiency. The application resulting from this model is expected to be a strategic tool for shipyards to prevent delays and maximize production results,” explained Zulfaidah.
This research significantly contributes to the development of Marine Engineering Systems science and increases the shipping industry’s competitiveness at the national level. As Secretary of the D4 Ship Construction Engineering Technology Study Program at the UNDIP Vocational School, Dr. Zulfaidah is committed to supporting technological innovation in the maritime sector.
