ShipUniverse: Digital Twin vs. Traditional Maintenance Approaches
Maintenance Type	Digital Twin Approach	Traditional Approach	Advantages of Digital Twins
Predictive Maintenance	Monitors real-time data from sensors to predict equipment failure before it happens. Maintenance is scheduled proactively based on wear and performance metrics.	Reactive: Maintenance is typically performed after a part fails or shows obvious signs of malfunction. Downtime is often required for diagnosis and repair.	Reduces unexpected downtime and costly repairs by addressing issues before failure. Extends equipment lifespan by preventing overuse or sudden breakdowns.
Condition-Based Maintenance	Continuously monitors the actual condition of components, such as engine temperature, pressure, and vibration levels, to determine when maintenance is necessary.	Scheduled: Maintenance is performed on a fixed schedule regardless of the actual condition of the parts or machinery. This can lead to over-maintenance or missed failures.	Optimizes maintenance timing by using actual condition data, reducing unnecessary maintenance and minimizing the risk of undetected issues.
Repair Scheduling	Uses historical data and real-time monitoring to schedule repairs at optimal times, minimizing the impact on operational availability.	Repairs are typically scheduled during planned dry-docking periods or after significant breakdowns, which can lead to delays if the vessel is in active operation.	Improves operational efficiency by aligning repairs with fleet schedules and minimizing disruptions to cargo transport.
Cost Savings	Digital twins optimize resource allocation by reducing unplanned repairs, lowering fuel consumption, and improving operational efficiency.	Costs are often higher due to frequent unscheduled repairs, inefficient fuel usage, and non-optimal maintenance timing, leading to higher long-term expenses.	Overall cost savings can reach 15-30%, depending on fleet size and operational scope, by minimizing unnecessary repairs and optimizing vessel performance.
Maintenance Records	Automated digital logs are continuously updated with real-time data, providing an accurate history of each vessel’s performance and maintenance needs.	Paper-based or manual digital logs are updated periodically, often relying on crew reports, which can lead to incomplete or delayed maintenance records.	Improves decision-making with up-to-date, accurate records, allowing for better planning and faster response to emerging issues.
