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.

Conductor Severance


Conductor Severance

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 and Pinning

Conductor Sectioning &
Pinning

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.

Slot Recovery


Slot Recovery

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.

Company page Since our founding in the early 1960s, Oceaneering has expanded and grown globally to service several industries such as the offshore energy industry, defense, entertainment, material handling, aerospace, science, and renewable energy industries. In 1964, Mike Hughes and Johnny Johnson formed a Gulf of Mexico diving company called World Wide Divers. The company grew in response to increasing demand for their services and in 1969 merged with two other diving companies to form Oceaneering International, Inc. To solve the toughest challenges, we do things differently, creatively, and smarter. As your trusted partner, our unmatched experience and truly innovative portfolio of technologies and solutions give us the flexibility to adapt and evolve, regardless of market conditions. Our mission is to solve the unsolvable. We thrive by creating industry-changing technically creative solutions for the most complex operational challenges under water, on land, and in space. Our five core values establish a common culture and demonstrate what is most important for us as a company. Since the beginning, the company has transformed from a small regional diving company into a global provider of engineered products and services. Today, we develop products and services for use throughout the lifecycle of an offshore oilfield, from drilling to decommissioning. We operate the world's premier fleet of work class ROVs. Additionally, we are a leader in offshore oilfield maintenance services, umbilicals, subsea hardware, and tooling. We also serve the aerospace, defense, and theme park industries. Underpinning everything we do, safety is not only the foundation of our core values, but it is vital to our unmatched performance record and company culture. The industries we serve are as diverse as they are complex. Whether we are engineering deepwater umbilicals or developing robotics for aerospace applications, the safety and health of our employees, vendors, and customers is an integral part of our day-to-day business. If we are working, then our responsibility is to be working safely. Since our inception in 1964, we have placed a high value on employee safety—from diving services and subsea inspection to vessel-based installation operations. We have and will continue to evolve not only our health, safety, and environmental (HSE) processes, but those of the industries in which we work. Although we have been fatality-free since 1999, our HSE journey goes beyond statistics. As our portfolio of services has grown, we have continued to prioritize and advance our approach to HSE.
