Underwater systems

Underwater systems are mainly used to lay pipelines and install underwater structures. These include what are known as ROV (Remotely Operated Vehicles) which are cable-operated under water. Bender ISOMETER®s monitor the cable connection and the underwater electronics for faults. An EDS system guarantees rapid troubleshooting.
