Underwater Electrical Connectors
Underwater Electrical Connectors
Our high-reliability underwater connectors are used by some of the largest and most prestigious organizations in the oceans. They’re used offshore, for geophysical research, for oil and gas exploration, for oceanographic and marine defense work.
Marine connectors, also called underwater connectors, offer billions of dollars in cost savings to customers whose projects have ventured below the surface. The deep immersion-specific series operates up to 7000 meters depth, giving you the reliability and performance you need for your operations.
With a diverse range of product types and brands, our R&D and manufacturing specialists can cover any need.
Whether it’s a custom project, or something for high-volume production, our product range covers everything including optical and electrical socket arrays, mechanical and electrical/optical strain terminations for ROVs, high-breaking strength umbilical termination systems, and field-installable optical and electrical terminal buffers.
Other applications include Dry-Mate Subsea Connectors and PBOF Assemblies, specially engineered for high-pressure oil and gas industry applications, including those that require tight tolerance production.
Our high-performance, high-pressure interconnect technologies have proven sealing performance in a wide range of applications. This includes shipboard, downhole, and underwater applications.
We offer high-density solutions for remotely operated vehicles that can withstand the most extreme conditions.
- High-Pressure woth a capacity of 10K PSI Open-Face Subsea
- High-Speed Electrical Connectors
- Energy and Fiber Optic Interconnects
- Hazardous Zone ATEx (Explosion-Proof)
- Ultra High-Density Solution
Underwater connectors are complicated and contain many small, highly-specific parts. To help readers better understand underwater connectors, authors proposed the concept of functional units- or one part that does a specific job. You can also think of them as independent concepts about underwater connectors. Multiple functional units may carry out some functions, but they’re always connected.
Underwater connectors can be classified into six functional groups: connecting, sealing, pressure-balanced, aligning, and locking units. These units can perform the following functions:
Connecting Unit provides the true and stable transmission of electricity, or optical signals (or both) between plug and receptacles, with desired specifications. These underwater connectors are in a mating state when connected. The connecting Unit is the primary functional Unit, whose design is demanded to ensure the stability and security of connections as well as reduce power loss on contact interfaces.
The Sealing Unit provides the watertight performance you need in underwater connectors. The sealing Unit can be the most important performance unit, so it must maintain a clean, stable and safe environment for the connecting Unit. The sealing Unit should protect connectors from seawater, sediments, grit and other contaminants while preventing leakage in PBOF connectors.
A pressure-balance valve is able to automatically create pressure so that the internal and external pressures are balanced. This helps reduce or eliminate the difference in pressure between underwater pieces of equipment. An excellent unit will have high reliability and sensitivity.
Aligning Unit improves the quality of connection by its mechanical structure. It is an important functional unit to help realize low power loss in underwater connectors, especially for optical connectors.
The Locking Unit locks plug and receptacle connectors to improve their reliability, stability, and connection quality. It should be able to mate or de-mate them without too much trouble.
It’s important to note that all of these functional units are intertwined and rely on each other. The design of each Unit must be taken into account so their relationship can work synergistically. As in the case of technology, it is necessary to also emphasize an integrated system-wide approach that includes not just hardware and software but data as well.
