Subsea Connectors

Hydro Group design, manufacture and pressure test underwater electrical and optical connectors and connector-cable assemblies for unique and challenging subsea applications. We typically work in three key energy markets, oil & gas, marine renewable energy, and defence, where we focus on technology and innovation for subsea applications.

The growing complexity of underwater engineering projects requires specialist capabilities, industry knowledge, and experience. Hydro Group has this capability and more; its dedicated engineering team has decades of industry knowledge and innovation, having achieved many unique connectivity solutions for various subsea applications. Supporting our design engineering team is a professional team of fully trained and equipment certified electrical engineers and technicians.

Our connectors have been tested extensively for performance and endurance, both internally and externally by third-party verification companies, and pressure tested to 10,000 PSI / 6860 MSW / 689 BAR. Importantly, our connectors have a proven track record over many years on local, national and international projects.
