Flow Assurance

Providing field-proven, engineered solutions to ensure the functionality and operational efficiency of your subsea infrastructure.

We have more experience remediating blockages from subsea flowlines than any other company. This experience, combined with our innovative technologies, enables you to restore production faster.

Operating from strategic locations around the globe, we address your needs and return flow to previous, or higher, rates in the most economical way possible.

Flowline Remediation Solution

Our single-deployment flowline remediation solution (FRS) removes blockages—hydrates, asphalts, and wax—to restore production in deepwater flowlines.

The MSV-deployed system specifically combats hydrates in critical large-volume flowlines. The on-bottom mudmat-based system includes subsea separation capabilities and features an emergency quick disconnect (EQD).

The FRS’s pressure transducers show upstream, downstream, and inhibitor inlet pressures in real time. Pressurized hydrate inhibitors can also be routed through the production piping in either direction to inhibit flowline fluids.

ROV SKID HRSs

Intervention Skids

Our flexible intervention skids effectively remediate small-volume blockages in control lines, chemical lines, umbilicals, jumpers, and under tree caps.

We have unparalleled experience and methodology where it concerns finding cost-effective solutions to blockages, including asphaltenes, hydrates, paraffins, and sludge.

The skids can be used for applications across the life of a field, including well development, start-up, active operations, well kill, and P&A. We ensure accurate dosing and increase uptime at any stage with multiple flow sensors and redundant instrumentation.

Subsea Pig Launchers and Receivers

Our pigging solutions are suited for applications from simple, single-pig deployment to complex, intelligent pig launch and retrieval.  

Our subsea- and surface-loadable pig launchers can be operated remotely or via ROV, and eliminate the requirement for a service flowline. We deliver further flexibility through customizable configurations that accommodate various pig types and capacities.

Our solution for remotely-operated subsea pig launching was awarded the Hart’s E&P Special Meritorious Award for Engineering Innovation.

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.
