Singapore Shipyard Upgrades 4 Overhead Cranes with Smart Anti-Collision System

Project Overview

As shipbuilding and offshore fabrication facilities continue to pursue higher productivity and safer lifting operations, crane safety management has become increasingly important in workshops where multiple overhead cranes operate simultaneously.

Recently, Yuantai Crane completed the deployment of a customized intelligent anti-collision system for four double girder overhead cranes at a shipyard in Singapore. The project was designed to improve operational safety in a complex upper-and-lower crane arrangement where multiple cranes frequently perform coordinated lifting tasks within the same workshop.

By integrating real-time positioning, collision-avoidance logic, and automatic crane protection functions, the system helps operators maintain safe crane operations while supporting efficient production in the shipyard's sectional fabrication workshop.

Project Information

Application Background: Challenges in Shipyard Multi-Crane Operations

Shipbuilding workshops often handle large steel sections, hull blocks, and structural components that require frequent lifting and transportation throughout the production process.

In this Singapore shipyard, four double girder overhead cranes operate within an upper-and-lower crane arrangement to support sectional assembly and material handling activities. As production volume increased and workshop space became more crowded, several operational challenges emerged.

Limited Visibility During Remote-Control Operations

Many lifting operations are performed using wireless remote controls. Operators naturally focus on the suspended load, surrounding personnel, and the immediate work area.

However, the position of cranes operating on another level is often difficult to observe in real time, making accurate distance judgment increasingly challenging during lifting operations.

Increasing Risk of Crane Interference

As ship sections and steel structures occupy more workshop space, the operating distance between upper and lower cranes becomes smaller.

Without continuous monitoring, unexpected crane interference or collisions may occur during simultaneous operations.

Frequent Multi-Crane Coordination

Multiple cranes often work together within the same production area.

When several cranes travel, hoist, or position loads simultaneously, maintaining safe separation distances becomes a critical requirement for both operational efficiency and personnel safety.

Higher Safety Management Requirements

Traditional safety management methods rely heavily on operator experience and visual observation. In complex lifting environments, human judgment alone may not always provide sufficient protection against potential collision risks.

Yuantai Crane Intelligent Double-Layer Anti-Collision Solution

To address these challenges, Yuantai Crane designed and implemented a customized intelligent anti-collision system that monitors the spatial relationships between upper- and lower-level cranes and protects against interference among cranes operating within the same workshop.

The system creates an additional layer of active safety protection beyond conventional operator observation.

Real-Time Position Monitoring for Upper and Lower Cranes

The anti-collision system continuously tracks the crane's movement and position during operation.

By monitoring the relative positions of cranes, trolleys, and lifting hooks, the system can accurately calculate safety distances between equipment operating on different levels.

Whenever cranes approach predefined safety zones, the system automatically initiates protective actions before a collision can occur.

This proactive protection significantly reduces risks associated with blind spots and limited visibility.

Intelligent Warning and Automatic Crane Protection

Instead of relying solely on manual observation, the system provides real-time risk assessment throughout the lifting process.

When equipment enters a warning zone, operators receive immediate alerts.

If the distance continues to decrease and reaches a predefined safety threshold, the system automatically activates speed reduction or stopping commands through the crane control system.

This intelligent control strategy helps prevent accidental collisions while minimizing disruption to normal production activities.

Improved Operator Efficiency and Reduced Workload

In traditional operations, crane operators often need to repeatedly stop and verify equipment positions whenever visibility becomes limited.

This not only reduces lifting efficiency but also increases operator workload.

After the implementation of the anti-collision system, operators can focus more attention on load handling and precise positioning tasks rather than continuously monitoring nearby cranes.

The result is a smoother and more efficient lifting process with fewer interruptions.

Multi-Crane Coordination in Complex Production Environments

Beyond monitoring upper-and-lower crane relationships, the system also supervises interactions among cranes operating within the same production area.

When potential interference is detected between multiple cranes, the system issues warnings and applies protection logic as necessary.

This coordinated protection mechanism helps maintain safe crane operation even during intensive multi-crane lifting activities commonly found in shipbuilding workshops.

Benefits for Shipbuilding and Heavy Industrial Facilities

The successful implementation of this project demonstrates how intelligent crane safety technologies can improve operational reliability in demanding industrial environments.

Key benefits include:

• Continuous real-time crane position monitoring
• Active collision prevention between upper and lower cranes
• Enhanced safety during multi-crane operations
• Reduced dependence on manual distance judgment
• Improved operator confidence and working efficiency
• Lower risk of equipment damage and production interruptions
• Better overall workshop safety management

Suitable Applications Beyond Shipyards

Although this project was implemented in a shipbuilding facility, the same technology can provide significant value across many heavy industries where multiple cranes operate within limited space.

Typical applications include:

Steel Structure Manufacturing
Production and transportation of large welded steel components.

Heavy Equipment Manufacturing
Assembly workshops for industrial machinery and large equipment.

Wind Energy Equipment Production
Handling of tower sections, nacelles, and large fabricated structures.

Railway and Transportation Equipment Manufacturing
Multi-crane operations in vehicle body fabrication workshops.

Energy and Process Equipment Plants
Production facilities handling large pressure vessels and industrial modules.

Moving Toward Smarter Crane Operations

As industrial facilities continue their digital transformation journey, crane systems are evolving from simple lifting equipment into intelligent production assets.

Projects such as this Singapore shipyard installation demonstrate how advanced monitoring and protection technologies can help create safer and more efficient lifting environments.

By combining lifting equipment expertise with intelligent control technologies, Yuantai Crane continues to support customers in upgrading crane safety, improving operational reliability, and preparing for future smart manufacturing requirements.

Conclusion

In shipyard fabrication workshops where lifting operations are frequent and equipment density is high, collision risks cannot always be eliminated through visual observation alone.

The intelligent double-layer anti-collision system implemented by Yuantai Crane provides a more systematic approach to crane safety through real-time monitoring, proactive warning functions, and automatic protection controls.
