Subsea Services


  • Wedding Cake – The process of cutting a wellbore into tiered layers to replace a damaged wellhead so that it can be controlled during the P&A process.
  • Window Cutting – Uses a mill to cut away an outer section of the wellbore to expose inner liners that may need to be Hot Tapped or serviced.
  • Slot Recovery – Allows Damaged or non-producing wells to be decommissioned without sacrificing its slot. Pinholes are drilled into the well slot casing to grip as it’s jacked out of the ground. Mactech will then cut sections as they are exposed.
  • Caisson Cutting – Easily perform high quality, positive cuts, suitable for internal cutting of platform legs and caisson removal of any diameter
  • Plate/Deck Cutting – Cutting large rigging holes into platform decks either submerged or standing to pass rigging through for heavy lifts
  • Drilling – Utilizing our hydraulic, electric, or pneumatic drills for pinning, or rigging holes when pulling casing.
  • Diamond Wire Cutting – Mactech brand Diamond Wire cutters available now! Using diamond wire saws to make large or critical cuts through single or multi strings and platform legs both topside and subsea.
