MDWS_DIAMOND_WIRE_SAW2In this regular feature for the Mirage blog we'll be taking an in-depth look at a specific portable machine tool.This week we take a look for the first time at their range of subsea equipment, namely the Diamond wire saw (6-80").

Diamond wire saw

Designed for underwater cutting on multi-string casings, piles, platform legs and wellheads, the wire saw is ideal for quickly cutting through dissimilar materials and resisting compressive forces whilst keeping costs low.

The saw uses abrasive cutting technology that is extremely effective in different subsea environments and allows circular cutting on all sides, preventing the wire from getting pinched on materials that would otherwise damage a lathe or milling type tool.

Top features

The saw boasts an auto clamp and auto feed for a smoother finish, diver compatible depending upon subsea depths and conditions, robust aluminium frame and powerful hydraulic drive.

For projects out-of-reach of human interaction, the saw is now available with a kit for an R.O.V operation - a process that greatly enhances safety and efficiency.

Models available from Mirage can cut between 6 to 80 inch O.D.

Case study

Subsea cutting with ROV operations has become a successful way to decommission platforms - a process that is used extensively around the world.

Mirage's machines have been used in the North Sea (UK and Norway), as well as the Gulf of Mexico for subsea cutting and surface projects too. Many projects have used drill pinning machines combined with diamond wire saws for a safer and slicker cut.
