Pile Cutting using a Diamond Wire Saw 


Our customer OPEC Systems, purchased Mirage Machine’s Diamond Wire Saw for a major project at Hamilton Wharves in Australia. The project involved the demolition of wharf structures and OPEC had to remove over 1500 piles. The piles varied from timber with concrete sleeves to hollow and concrete filled steel piles some of which exceeded a metre in diameter.


Three full time dive crews were deployed by OPEC, using a range of cutting solutions that included the use of Mirage’s MDWS1638 Diamond Wire Saw which for cutting the 200 steel and concrete piles.

The saw operates by clamping onto and cutting cylindrical items using hydraulic clamping jaws and an automatic feed. 

In addition to providing the Diamond Wire Saw, Mirage also supplied the diesel driven hydraulic power pack, hose kits and the control panel. The project lasted for four months and the Diamond Wire Saw was in continuous use every day.


The client’s project was successful, with 200 steel and concrete piles being removed, thanks to the Mirage Diamond Wire Saw.

Rick Wakefield, OPEC Systems (Subsea Dive Supervisor) commented,"the Diamond Wire Saw was reliable and easy to use". 

Basil Tyson (Research and Development) at OPEC Systems said "We certainly put the saw through its paces. It was in the water for pretty much the whole duration of the project and aside from usual maintenance requirements we had no issues with it. The saw successfully fulfilled its purpose. The service from Mirage Machines was excellent. Chris Hayton (Technical Sales) was easy to deal with and was prompt to respond to our requests. The parts we needed always came in good time."
