Engineered Solutions

Problems with on XT and Manifolds?

It could be easier to fix than you imagine

A number of older fields are candidates for life extension.
The aging subsea systems in operation on these fields must be addressed.

ES 2 - Engineered Solutions

Aging subsea components

Can you trust your aging subsea equipment?

ES 3 - Engineered Solutions

Increased risk of pollution

Emissions from subsea installations will impact the environment.

ES 4 - Engineered Solutions

Increased risk of operational downtime

Life extension increases the risk of failure and leakages, leading to potential downtime, if aging equipment is not addressed.

Our bespoke subsea repair solutions enables operation while maintaining production and system integrity.

With more than 250 skilled engineers and operational experts, our portfolio and experience enable us to solve planned and unplanned subsea repair projects, rapidly and cost effectively. Our track-record shows more than 800 jobs successfully completed on time and on budget.

We offer fully integrated project management and engineering solutions for all kinds of subsea repair projects:

Case Study

Control Line Leak Repair


Severe leakage of water based control fluid in control line located below National-Coupler/Treecap on XT


  • Limited visibility and complicated access
  • Operating ROV manipulator near critical equipment on XT
  • A high producing well, therefore extremely critical to avoid downtime


Oceaneering provided one primary and two backup solutions, all three with complete tooling suites. The primary solution that was chosen by the client involved re-tightening the fitting between the tubing and the National Coupler with bespoke tooling.

Oceaneering delivered a complete solution to the client in a fairly short time and completed the project with great success.

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.
