    AUV: Autonomous Underwater Vehicle

    The oil and gas industry use AUV's (Autonomous Underwater Vehicles) to make detailed maps of the seafloor before they start building subsea infrastructure; pipelines and sub sea completions can be installed in the most cost effective manner with minimum disruption to the environment. The AUV allows survey companies to conduct precise surveys or areas where traditional bathymetric surveys would be less effective or too costly.


    Hydro Group are at the forefront of AUV & UUV technology for which we offer custom design solutions including: fibre optic cable, fibre link penetrators, proximity switch, variety of optical and electrical cables and fibre optic connectors.

    AUV: Autonomous Underwater Vehicle: Optical and Electrical Connection System / HDM Connector range (coaxial / electrical / optical)

    Hydro Bond Engineering Ltd design and manufacture the industry acclaimed HDM connector series. The HDM series has standard configurations with high density electrical paths for ROV (remoted operated vehicles), AUV (autonomous underwater vehicle) and UUV (unmanned undersea vehicles). Applications include communication module applications, 4 pin high voltage/ high current for hydraulic power unit (HPU) applications, optical fibre (fiber) paths for communication of video, coaxial paths for video or a combination of all the above. Rated to 3,450 MSW as standard and 6,000 MSW option to meet most ocean floor applications.

    Hydro Bond Engineering HDM series electrical connectors are marine renewable industry proven and we have developed shell sizes and pin configuration up to 11.1 kV at 320 amps current rating. Partial discharge technology is also used in our termination process to assure continuity and insulation resistance of the connection in long life subsea applications.

    Our in house engineered and developed optical technology is at the forefront of harsh environment requirements.Our products have been extensively tested both internally and externally and are field proven on major local, national and international projects.

    Our optical Engineers and Technicians are fully trained and certified on our equipment by City & Guilds (optical fibre installation and testing singlemode fibre course).

    FIBRE LINK DEEP FIELD PENETRATOR: can operate at 3000 MSW (310 Bar). The design and construction of the optical fibre penetrators can be limited due to the cable design and construction. The Hydro Fibre Link deep field penetrator is most suitable for sea bed ploughs, ROV, MUX systems and deep sea platforms.
