Dredging

Our diver- or ROV-deployed dredges excavate pipelines for abandonment, inspection, and maintenance work by removing clay, rock dump, and other sediments.

Pile Dredging

Use our pile dredges for both abandonment and new field development, in both deep and shallow waters. Our hydraulic pile dredges are best suited for shallow-water use.

Our deepwater pile dredge, a 2015 Offshore Technology Conference (OTC) Spotlight on New Technology℠ award winner, is electrically driven with pumps that provide water jetting and suction to excavate piles to 10,000 fsw (3,000 msw).

The jetting provides a 360° pattern to fluidize the soil inside the pile, and then suction pumps remove the soil from the pile.

Deepwater Pile Dredge Data Sheet

Conventional Dredging

To effectively remove subsea sediment and soil, we offer a broad range of dredge sizes and deployment options. Our 6-in (150-mm) dredge can be deployed as a stand-alone system manipulated by a diver at the seafloor, or as part of an integrated ROV package. When used with an ROV, the dredge can be cage or belly mounted.

For pipeline excavation, cuttings remediation, salvage, and other offshore tasks, we offer expanded dredge sizes from 10 in (254 mm) to 16 in (406 mm). Our larger dredges can be deployed as stand-alone systems to remove greater volumes of seafloor debris.

Backfilling and Cuttings Remediation

Our dredges have a proven record of successfully backfilling previously excavated locations.
For deeper wells and larger wellhead structures containing increased drill cuttings deposits, our dredging equipment collects and transports cuttings to designated disposal areas. Subsea dredges with attached collection buckets keep drill sites clear of debris. We use an ROV to make subsea connections, and our drill cuttings collection tool can be deployed without a rig.

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.
