M Series Junction Plates

Multi-line, high-flow, ROV-operable connection solutions
Meet your diverse project requirements with our M Series junction plates with fixed, configurable, and removable assemblies.

The plates enable remotely-connecting subsea structures to support chemical injection by preventing well blockage, supply hydraulic power to open and close subsea mounted valves, and facilitate well annulus pressure monitoring.

  • Populated with appropriately-sized hydraulic couplings to ensure the highest integrity and optimization of functions
  • Operated with conventional API 17D ROV tooling
  • Incorporate an extremely reliable, patented, and pre-threaded latch mating system to deliver a safe, efficient connection solution
  • Product portfolio includes ancillary equipment such as logic caps, marine growth covers, and test and flushing plates

Our junction plates are often included in flying lead systems or on manifolds, subsea X-mas trees, and subsea structures.

Subsea Distribution Units

Project-specific designs for electrical distribution units, hydraulic distribution units, and subsea distribution units meet your challenges for optimized subsea distribution of functions.
Deployed to the seafloor, distribution units are configured to include the hydraulic and electrical interfaces that support your system. From the routine to complex, our engineers deliver the most effective, robust solutions to ensure production and uptime.

Hydraulic Flying Leads

Providing safe and efficient connections between subsea distribution hardware
Connect your subsea infrastructure—from umbilical termination assemblies (UTAs) and manifolds to X-mas trees and subsea distribution units—using our field-proven flying leads. Our flying leads support the safe and efficient conveyance of hydraulic fluid and chemicals.

Combining a primary conduit section—typically steel tubes or thermoplastic hoses—with a termination head weldment and the required ROV-operable junction plate provides full functionality.

  • Modular designs for hydraulic, electro-hydraulic, and hybrid applications
  • Bundled or extruded conduit sections
  • ROV-friendly
  • Extensive track record
  • Solutions for long-term stowage, long-distance transportation, and installation

Subsea Umbilical Termination Assemblies

Using standard parts to deliver customized solutions
Our umbilical termination assemblies (UTAs) are configured using modular components to meet your project requirements for robust, subsea connection solutions.

Your most challenging installation and operational requirements are met with our standardized, configurable designs.

Why modular?

  • Improved schedule through parallel manufacturing
  • Improved access for welding and assembly
  • Supports early completion of load and pressure testing
  • Immediately apply lessons learned and benefit from repeatability of designs
  • Configurable side panels offer hydraulic, electrical, and fiber optic connectivity solutions

We also offer custom-designed UTAs to meet your operational requirements.

Topside Connection Hardware and Ancillary Equipment

Connection systems are not complete without ancillary equipment and topside hardware. From I- and J-tube seals to umbilical weak links, we meet the varied design challenges your systems pose.

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.
