  • European Back-to-Back Vessel Agreements
  • Vessels ready to mobilize, equipped with remotely operated vehicles (ROVs) and survey spreads
  • Dredge Act-compliant cable burial
  • Noise mitigation
  • Grouting/bolting services
  • ROV support services

Cable Installation Support

Our vessels have installed over 932 mi (1,500 km) of subsea products. We understand the challenges of safely handling a valuable commodity. As the EPCI partner of choice, we support you on pre- and post-lay surveys, PLGR operations, touchdown monitoring, and technician support for pull-in and hang-off operations, through to burial and protection.

Jetting

The Ocean Manta is a step change in jetting. For shallow water projects, our patented energy containment system (ECS) is ideal for longitudinally stiff cables and ensures that soil stays fluidized longer, providing the best opportunity to meet the specified depth of burial. For environmentally sensitive areas, low particulate suspension and surface mounted pumps make Ocean Manta the most environmentally friendly jetter on the market.

  • Compact and lightweight
  • Deployable from construction or AHTS vessel
  • Excels with longitudinally stiff cables
  • Reduces second-pass trenching
  • Lowest particulate suspension in the water column of any trencher
  • Lowest subsea noise profile on the market

Cable Lay Equipment Rentals

Meet your offshore installation needs with our carousel and tensioner rentals

Our 46 ft-diameter (14 m-diameter) carousels are ideal for a wide range of subsea products, from inter-array cables to export cables, flexible pipelines, and umbilicals. The carousel system is designed for single lift installation.

The system can be used as a standard carousel for typical flexible products or as part of our PREP system. In this case, the carousel can be used in both horizontal and vertical orientations.

Additionally, we own and lease two 10-ton hydraulic drive tensioners designed to complement the carousel system. Each tensioner has a dedicated hydraulic power unit (HPU) and control unit. A complete hose set and spares kit is included as part of the rental.

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.
