The first intelligent net cage towing and positioning in the country has been successfully completed!

Recently, the intelligent net cage "H399" designed and built by CIMC Raffles was delivered at the Yantai base. However, how to tow this "big guy" to the designated location and install it accurately according to customer requirements has become a daunting task for our Xinyun company. The "H399" intelligent net cage is the first deep-water bottom-sitting net cage in China, made of steel and non-self-propelled. The net cage has a Size of 66 meters × 66 meters × 35 meters, designed with a square truss structure, featuring four tubular pile legs and square sinking pads. The overall structure includes a top ring, middle ring, bottom ring, vertical braces, and horizontal braces. The net cage itself has no self-propulsion capability, based on its overall requirements and structural characteristics.

The net cage itself has no self-propulsion capability, and based on its overall requirements and structural characteristics, this towing operation was conducted using wet towing.
  After more than forty hours of towing, the net cage was brought to the designated sea area, followed by a precise positioning process lasting more than ten hours. Based on the flow speed and direction of the sea conditions at the positioning site, we chose the right moment to carry out the ballast water operation, and finally, in the evening, the net cage settled on the bottom, meeting the precise positioning requirement of "5 meters deviation, 2 degrees angle."
  Thus, our company successfully completed the first case of net cage towing and precise positioning operation in China.
