Our ROV- or diver-deployed cutting solutions ensure reliable and efficient severing of subsea assets.
We use the abrasive waterjet cutting (AWJC) method during well abandonment and platform decommissioning operations. With AWJC, a high-energy jet of water-borne abrasive particles is used to quickly and safely cut hard steel alloys. This technology eliminates the use of explosives and reduces the risk of ignition.
External abrasive waterjet cutting tools are used for cold cutting applications. The diver-deployed solutions are available for shallow-water applications, while our ROV-deployed solutions meet the demands of deepwater decommissioning and cutting activities.
The multi-string conductors are cut below the mudline using the Oceaneering’s powerful abrasive water jet cutting (AWJC) technology. The Internal Multi-String Cutting Tool (IMCT) can cut up to five layers of casings internally in a single run and has the best track record in the industry with more than 3000 cuts around the globe.
Conductor Sectioning &
Oceaneering offers sectioning and pinning services for the complete removal of the conductor from the installation. This is typically done during the decommissioning phase, but is also completed in the case of slot recovery operations on producing installations. Operations can be carried out with support from a platform derrick, jack-up rig or suitably rated crane.
Out toolkit includes the Internal Multi-String Cutting Tool, non-sparking Guillotine Saws, Dual Drilling Machines (DDM), Lifting Pins, Securing Pins, and Conductor Washers to remove marine growth.
