FAT, SIT, and Offshore Execution

Our highly experienced teams work to ensure the suitability of your infrastructure by completing factory acceptance testing (FAT) and systems integration testing (SIT). We execute project-specific testing and generate required reports, and are well equipped to complete immediate intervention and troubleshooting in the unlikely event that testing reveals a nonconformity.

Tie-In, Hook-Up, and Commissioning (HUC)

We help you achieve first production on time and within budget, regardless of installation type. Our extensive experience positions us well to meet your requirements for solutions and support ranging from deepwater gas fields and floating production, storage, and offloading (FPSO) units to onshore facilities.

Deepwater Operations

We deliver leading solutions for deepwater operations—from routine to extreme. We meet your requirements for global support in commissioning and operating subsea systems in the harshest and most challenging of environments.

Interventions, Workovers, and Decommissioning

We meet your needs for global subsea intervention, work over, and decommissioning using ROV- and diver-based methods. Using our experience and expertise in subsea engineering and project management, we develop subsea intervention and abandonment procedures and complete rig capability assessments.

Our innovative and practical designs provide tailored solutions to improve efficiency of well interventions and activities.

  • Light workovers
  • Subsea control module and pod replacement
  • Buoy and mooring system repairs
  • Well abandonment
  • Final field abandonment

Inspection, Maintenance, and Repair (IMR)

We ensure you are able to maintain uptime and mitigate the effects of unplanned repairs with our comprehensive inspection, maintenance, and repair programs. We develop fully-integrated subsea project solutions using the latest standards and risk-based methodologies. Our services cover the full life cycle model of production monitoring, inspection execution, engineering criticality assessment (ECA), maintenance planning, and scheduling.

We provide turnkey solutions tailored to meet the requirements of your scope of work.

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.
