The J.A. King team is proud to have been a part of the raising and righting of the H.L. Hunley Submarine in Charleston, SC. Our Integrated Solutions Division designed and built the monitoring system that showed and recorded in real-time the weight distribution across the submarine as it was being rotated.  This system allowed the Hunley project engineers to monitor the horizontal and vertical loads using 36 custom engineered load monitoring plates.

Our custom engineered monitoring system was the instrumentation system and software that the engineers used to determine exactly how much to move each sling – millimeters at a time over 2.5 days.  This level of monitoring was extremely pertinent as to not damage parts of the vessel when rotating. Check out some videos of the process below.
