Mactech Completes Deepwater 120-Inch Pile Removal Using Diaquip Diamond Wire

Removing large-diameter subsea piles presents several technical and operational challenges, including:

• Cutting through thick steel structures in a deepwater environment
• Maintaining consistent cutting performance under heavy loads
• Operating reliably in demanding offshore conditions
• Minimizing installation time and diver intervention
• Reducing the risk of downtime during critical offshore operations

With offshore projects operating to tight schedules, reliability and cutting efficiency are essential to keeping vessel time and project costs under control.

Mactech utilized its large-capacity inline diamond wire saw equipped with Diaquip diamond wire to complete the cutting operation.

The combination of specialist cutting equipment and high-quality diamond wire delivered:

• Reliable cutting performance on large-diameter steel structures
• Smooth, controlled cutting action
• Consistent performance throughout the operation
• Reduced risk of wire failure and unnecessary downtime
• Efficient execution in challenging subsea conditions

Diaquip’s diamond wire provided dependable cutting performance while complementing Mactech’s proven offshore cutting technology.

• Safe removal of 120-inch OD subsea piles
• Reliable cutting performance at approximately 122 feet below sea level
• Clean, controlled cuts
• Efficient project execution with minimal downtime
