The ISRSystem has been engineered specifically to enhance ship board jointing operations on switchable branched powered telecommunication systems, enabling the majority of the system to remain active during the repair operation.

As the name suggests the “In Service Repair System” permits the marine operator to safely perform repair and jointing operations on a de-powered segment of a cable system, while the remaining segments remain active. The system has been designed and tested with absolute safety in mind and has been used with great success on numerous repairs to date.

Consisting of three primary components the ISRSystem has been engineered for use with both Universal Joint and Millennia Joint technologies. Other jointing technologies can be included if required.

The first component of the system are active Sensors and Alarms. Designed and tested to the highest standard this part of the system provides continuous monitoring for current on the cable throughout the entire repair operation. Built with full redundancy against power failure, the system will activate upon the sudden presence of a current above 100mAmp or 250mAmp (selectable). The bespoke switching unit is rated to 10kV (tested to 25kV for 1 minute), has passed 28kV impulse +/- 15 times and has been tested to 400A. The system is capable of withstanding a BU failure when the switch is in the open or closed circuit condition.


The second component of the system are the earthing tools and equipment. Again designed specifically for this application the tools provide continuous earth protection to each power conductor within the cable. Tested to 400A the simple to use tools provide effective and complete protection for the operator. Ease of use means quicker operational times.






The third component of the system is the extensive library of procedures which are used in conjunction with the jointing procedures and cover nearly all current cable types in use. Those cable types not currently covered can be easily and quickly introduced as and when required. Full training for all crew members, cable engineers and jointing personnel ensures that the system is used both safely and effectively, maximising the repair operation.
 

Ocean Cable Technologies ISRSystem has been used with great success on numerous system repairs and to-date has been installed on 4 separate repair vessels.

All tools and equipment have been designed and electrically tested by an independent test establishment to 400Amps. The Sensor and Alarm system have been rated to 10kV in accordance with British Standards.
