Pile Cutting And Removal Services

Underwater pile cutting is the process of cutting through metal structures of a Pipe that require repairs or modifications. This process is commonly used for removing damaged sections of the pile or other metal components of the piles. There are two main types of underwater ship cutting wet cutting and dry cutting.

Wet cutting involves using a specially designed cutting torch that is capable of cutting through metal underwater. This process is commonly used for cutting through the ship's hull or other metal structures. Dry cutting, on the other hand, involves creating a dry environment around the cutting site using a hyperbaric chamber. Dry cutting is commonly used for precision cutting of the ship's metal components, such as pipes and valves.

Types Of Piles And Cutting Requirements

Different pile materials require tailored cutting methods to maintain structural integrity:

  • Concrete piles are trimmed precisely using hydraulic croppers without harming reinforcement.
  • Steel piles are cut smoothly and cleanly using high powered cutting tools with minimal disruption.
  • Precast piles are cut using controlled methods to protect surrounding structures and materials.
Underwater Pile Removal

Underwater Pile Removal

Pile removal ensures obsolete or damaged piles are safely extracted or severed to clear the way for new marine structures. Our methods include:

  • Mechanical extraction uses cranes or excavators to lift piles out of position.
  • Hydraulic cutting and lifting involve cutting piles at depth and then removing segments for disposal.
  • Explosive cutting (special applications) is used for underwater or heavily reinforced piles where other methods are impractical.

Techniques For Pile Cutting

Modern projects use several methods depending on pile size, depth and material:

  • Manual cutting uses traditional chisels, hammers and jackhammers, but it is slow and labor intensive.
  • Hydraulic pile croppers are excavator mounted tools that deliver fast, consistent and uniform results.
  • Robotic cutting systems provide automated precision for complex pile profiles and high accuracy work.

Why Are Pile Cutting And Removal Necessary?

These services are critical for accurate foundation work, safe marine construction and infrastructure upgrades:

  • Leveling and finishing ensure pile tops are uniform for stable platforms.
  • Structural modifications adjust pile length or profile for revised designs.
  • Decommissioning and site clearance remove outdated piles to prepare for new installations.
  • Integration with pile caps or beams provides flush connections for optimal load transfer.
