Background
A major Singapore shipyard is one of the country’s most established ship repair and fabrication facilities. Originally built in 1938 as a British Royal Naval base, the facility was later converted into a commercial shipyard after Singapore’s independence.
Today, the shipyard operates five docks with a total capacity of 775,000 dwt, nearly four kilometers of sheltered berthage, and one of the deepest dry docks in Southeast Asia (100,000 dwt). With such a massive operational area, managing tools, equipment, and maintenance assets is a daily challenge.
To improve efficiency and reduce downtime, the shipyard deployed UHF RFID readers and handheld computers to modernize its asset tracking system.
The Challenge: Manual Asset Tracking Was Slowing Operations
Like many large shipyards, the facility handles thousands of maintenance tools and management assets across multiple docks. However, their previous process relied heavily on manual recording.
Here were the main issues:
- Inspectors had to manually write down asset information during dock inspections.
- Paper-based reporting was time-consuming and prone to errors.
- Management had no reliable way to confirm inspectors’ attendance and on-site activity.
- Fault information was not delivered in real time.
- Maintenance planning was often delayed, leading to operational losses.
In a fast-paced ship repair environment, even small delays can result in significant costs.
The Solution: UHF RFID and Handheld Readers for Real-Time Asset Tracking
To overcome these challenges, each dock maintenance tool was equipped with either:
- A barcode label, or
- A unique electronic UHF RFID tag
The shipyard deployed the Chainway C3000 handheld computer, which integrates:
- 2D barcode scanning
- UHF RFID reader
- Wi-Fi connectivity
- Mobile data collection
With this solution:
- Inspectors simply scan the RFID tag or barcode using the handheld device.
- The system instantly retrieves the asset’s information.
- If there is a breakdown or fault, inspectors input details directly into the device.
- Data is uploaded in real time via wireless network to the central system.
This eliminates paperwork and ensures maintenance teams receive instant updates.
The Results: Faster Inspections, Better Control, Lower Costs
After implementing the UHF RFID solution, the shipyard achieved several improvements:
1. Faster and More Accurate Asset Tracking
Tracking dock maintenance tools became more efficient and reliable. No more manual logs or missing records.
2. Paperless On-Site Inspections
Workers no longer carry paper forms. Using portable RFID PDAs, they complete inspections digitally—saving time and operational costs.
3. Better Workforce Monitoring
Administrators can now verify inspectors’ attendance and on-site activities more effectively.
4. Real-Time Maintenance Planning
Thanks to Wi-Fi connectivity on the handheld devices, breakdown reports are uploaded instantly. Maintenance plans can be created immediately, reducing downtime.
5. Automatic Maintenance Records
All tool maintenance records are automatically generated and stored in the database. This makes future audits, analysis, and asset lifecycle management much easier.

Why UHF RFID is Ideal for Shipyards
Shipyards operate in harsh environments with metal surfaces, large open areas, and heavy equipment. UHF RFID technology offers:
- Long reading distance
- Fast multi-tag reading
- Reduced human error
- Real-time data visibility
- Better preventive maintenance planning
For industries such as ship repair, marine engineering, oil & gas, and heavy fabrication, RFID-based asset tracking significantly improves operational control and cost efficiency.
