Overview
In the demanding world of maritime operations, hull integrity is non-negotiable. Manual inspection workflows, paper-based logs, and scattered maintenance records often lead to compliance issues, repair delays, and avoidable risks. Our team at DEIENAMI set out to solve this by developing a smart, end-to-end Hull Check & Maintenance Management System tailored specifically for fleet operators, marine engineers, and vessel maintenance teams.
This platform enables real-time inspections, maintenance scheduling, photo documentation, and compliance tracking—all from mobile tablets and web dashboards, ensuring every vessel in the fleet is operating at optimal structural health and adhering to international marine safety standards.
Client Challenges
The maritime operator we worked with faced challenges typical of large-scale fleet operations:
- Inspection data spread across paper reports, emails, and local spreadsheets
- Difficulty coordinating inspection schedules across fleets and ports
- Lack of visual documentation and historic maintenance records
- Complex reporting needs for stakeholders, port authorities, and insurers
- Difficulty ensuring compliance with IMO, Class Society, and flag-state regulations
Our Solution
We engineered a comprehensive system that digitizes the entire hull inspection and maintenance lifecycle, from onboard data collection to backend reporting and analytics.
🛠 Platform Features
✅ Inspection & Defect Logging
- Inspectors use Android/iOS tablets (Kotlin & Swift apps) to log cracks, corrosion, deformation, or structural anomalies
- Each finding includes photo/video evidence, coordinates on vessel layout, and severity tags
✅ Maintenance Scheduling & Alerts
- Customizable digital checklists for recurring inspections
- Auto-reminders for drydock schedules, overdue maintenance, or high-priority risks
- Task allocation and calendar sync for on-ground field staff
✅ Multi-Vessel Dashboard
- Fleet-wide overview for HQ and port operations
- Track inspection dates, overdue actions, hull condition indexes
- Compare defect patterns across similar vessels (great for predictive strategies)
✅ Analytics & Reporting
- Auto-generated PDF reports, steel weight calculations, surface corrosion areas
- Risk-based prioritization using custom matrices
- Exportable logs for Class surveys or port clearance documents
Tech Stack Highlights
| Component | Stack Used | Reason |
|---|---|---|
| Backend | .NET | Robust enterprise framework for logic and APIs |
| Database | PostgreSQL | Reliable RDBMS for structured inspections data |
| Web Interface | VueJS | Lightweight, modern dashboard for browser access |
| Mobile Apps | Kotlin (Android) + Swift (iOS) | Native performance, used by field inspectors |
| Hosting & Infra | Client-managed on-prem and cloud | Configurable for air-gapped fleet deployments |
Real-World Impact
Within 6 months of deployment:
- 🔍 100% digitization of hull inspection processes across 20 vessels
- 📉 40% reduction in inspection-to-report turnaround time
- 💾 Thousands of records archived securely with visual context
- 🧮 Improved accuracy in coating condition tracking, crack frequency analysis, and drydock budget forecasting
- 📈 Boosted compliance visibility for insurers and maritime regulators
Built for Real-World Crews
Our system is designed for:
- Onboard inspectors and engineers using rugged Android/iOS tablets
- Fleet HQ staff managing compliance, budget, and maintenance scheduling
- Port officials and auditors accessing real-time inspection logs securely
- Class Societies who need visual + data-based documentation before certifications
After-Sales Support & Roadmap
We continue to support the client with:
- Monthly performance audits and database optimization
- New feature rollouts (e.g., ultrasonic thickness API integration)
- Continuous patch updates and enhancements based on field feedback
- Data migration from old Excel logs into the new platform
Future plans include AI-assisted defect prediction, wear pattern heatmaps, and voice-enabled inspection tools for hands-free logging.
Conclusion
This project underscores DEIENAMI’s expertise in building rugged, scalable platforms for mission-critical environments like shipping and offshore operations. With a keen focus on safety, data integrity, and usability, our Hull Maintenance System empowers maritime operators to go fully digital, improve vessel longevity, and stay ahead of global compliance standards.
