Building on our track record of reliable cutting and tooling services, we offer turnkey solutions that meet the demands of the industry’s largest work scopes. At the end of a field’s life, we efficiently remove assets of all types—manifolds, pipelines, wells, umbilicals, and topside set-ups.

When disconnecting assets, choose a decommisioning company that
delivers best-fit solutions by Connecting What's Needed with What's Next™.

Flexible Project Execution

Our technical expertise and ability to react to unplanned events during project execution make us the industry leader in integrated oil and gas decommissioning services. Our solutions reduce mobilization costs, which reduces health, safety, and environmental (HSE) risk throughout an offshore decommissioning operation.
Because we are experienced in managing projects from top to bottom, and even across multiple assets, we ensure compliance with varied and stringent government regulations.

Customized Plug and Abandonment Solutions

We collaborate with you to meet your specific plug and abandonment (P&A) requirements, using scalable combinations of Oceaneering technologies and services. We combine competencies from across our organization, and around the world, to best serve your operation.

Our integrated decommissioning solutions can incorporate one or more of the following services.

Cutting

Our cutting tools include solutions for shallow and deepwater internal and external abrasive waterjet cutting, plus internal cutting tools for piles and caissons. Additional mechanical cutting functionality is provided by an extensive suite of saws and sectioning tools.

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.
