In modern concrete cutting, wire saw demolition are essential for their flexibility, reliability, and high efficiency. They are particularly suitable for complex demolition projects, including large structures, irregular shapes, and underwater installations.
This case study highlights the use of a diamond wire saw in a floating solar photovoltaic (PV) system project, focusing on underwater concrete pile removal.
1. Project Background
During early construction, the client pre-installed a large number of concrete support piles. Later, they discovered that too many piles were installed, requiring partial removal to comply with project approval requirements.
The piles were underwater, making traditional manual diving cutting expensive and risky.
A safer and more efficient solution was required.
2. Challenges Analysis
The project faced several challenges:
Complex underwater environment: Difficult to deploy cutting equipment
High cost and risk for divers
Limited visibility underwater, reducing cutting accuracy
Large number of piles, increasing project duration and pressure
A cutting solution was needed that could replace manual diving and allow remote shore-based operation.
3. Solution: Diamond Wire Saw Underwater Cutting
After evaluating site conditions and project requirements, we recommended a remote underwater diamond wire saw solution.
Advantages of the Solution
1. Track-mounted equipment for easy mobility
No heavy manual handling required
Quick deployment on soft or wet surfaces
Significantly improves on-site efficiency
2. Shore-based cutting without diving
Suitable for concrete piles up to 20 meters deep using a 22kW wire saw
Safer for workers
Lower operational costs
Higher cutting efficiency
3. High cutting efficiency and adaptability
Stable and efficient underwater cutting
Fast cutting speed
Not restricted by pile shape or orientation
Smooth and precise cut surface
No need to remove surrounding structures

4. Project Outcome
The client successfully implemented the wire saw solution on-site.
Results achieved:
✔ No divers required
✔ Significantly reduced safety risks
✔ High cutting efficiency, project completed ahead of schedule
✔ Cost savings compared to traditional underwater cutting
✔ Successful removal of excess floating solar concrete piles
The client highly appreciated the technical expertise and results delivered.
