Since the last decade when DSI Robotics ventured into the field of underwater robotics, we had to overcome several obstacles as we tried to perfect our range of solutions for underwater inspections. One such major hurdle was the lack of underwater cable rated for use as an umbilical available in the Indian market. The requirement was for a robust cable that can be used for underwater applications and sustain the tensile loads typical of umbilical cables. At the same time, the cable was to retain its coiling-uncoiling capability requiring a highly flexible unarmored cable capable of very tensile loads. While such cables are easily available abroad, import of an item like cables was never practical. Besides, the needs of the Indian market were very different from the offerings from western suppliers.
Slave to its never-ending desire for perfection, DSI set upon designing its own multi-conductor cable optimized for underwater umbilical use, and shortlisted several specific Indian suppliers for the required raw material. The end result was an extremely robust, rugged and high-performance underwater cable, aka, the BRC-1509.
