OFFSHORE CAPABILITIES
Mactech offshore Subsea Machining Solutions and equipment have been in place for several years. Activities such as steel structure removal, decommission of platforms, well plugging and abandonment are just a few of the ongoing projects that Mactech is involved with. A majority of this work takes place in water depths ranging from 85ft to 135ft.
Hot Tapping
Both Multi Sting and Direct Hot Tapping to relieve trapped pressure in wellbores prior to
plugging or service work
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
Valve Drilling
Uses a pressure equalized drilling unit to drill through non-functioning valves so access can be gained to the wellbore
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
