Diving

We are a leading provider of air, mixed gas, and saturation diving services for the oil and gas industry.

Specialized Diving Services

We own and operate specialized equipment used to perform a wide range of offshore platform structural repairs, inspection services, pipeline repairs and re-routes, grouting repairs, and specialized hyperbaric and wet welding. 

Our diving services also include non-asset work performed to meet various government and customer requirements.

Diving Support Vessels

We support diving operations with the world's premier remotely operated vehicle (ROV) fleet and one of the youngest diving support vessel (DSV) fleets in the Gulf of Mexico. Achieve your objectives more efficiently with our four-point and dynamically positioned (DP) air and saturation diving vessels.

Ocean Quest

Our DSV Ocean Quest is a U.S.-flagged, Jones Act-compliant 150-ft by 36-ft (46-m by 11-m) four-point anchor dive vessel.

The vessel is outfitted with 30-person accommodations (nine accommodations for vessel crew members and 21 for offshore workers). It also has built-in diving and ancillary equipment, and is capable of supporting air and mixed-gas diving to 300 ft (91 m). Additionally, the vessel is equipped with two electric welding machines, a built-in tool compressor, and a built-in three-stage 6-by-6 diver jet pump.

Ocean Inspector

Built in 2004, the DSV Ocean Inspector is designed to support inspection, maintenance, and repair (IMR) work, and is ideally suited for the underwater inspection work required of Gulf of Mexico operators in water depths to 300 fsw (91 msw). The 130-ft (40-m), state-of-the-art DSV has built-in diving equipment, dive control, and decompression chambers that free ample deck space for safe working conditions and project-specific equipment.

Ocean Patriot

The DSV Ocean Patriot is the industry’s only U.S.-flagged, Jones Act-compliant DP vessel operating in the Gulf of Mexico today. The 240-ft by 54-ft (73-m by 16-m) ABS-classed vessel provides a range of ROV support saturation diving services, for which it was recommissioned in December 2011.

Welding Services

Our certified welders perform construction and maintenance welding services including underwater wet and dry hyperbaric welding repairs. Our divers are also experienced in grouting, platform repairs, pipeline inspection and maintenance, and pipeline plug and abandonment.

Hyperbaric Rescue Facility

From Mimir Marine, a leading manufacturer and operator of hyperbaric reception facilities (HRFs), we have purchased a portable HRF in support of our saturation diving services. Our team based in Morgan City, La., currently operates this HRF system.

Industry Standards

To provide the highest level of customer confidence, in the Gulf of Mexico and worldwide, we can deploy equipment and divers that not only meet the standards of the International Marine Contractors Association (IMCA), the International Association of Oil & Gas Producers (IOGP), and the Association of Diving Contractors International (ADC), but that also meet all recognized industry standards and, of course, your own high standards.

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.
