摘要： A system for underwater material placement and release is provided that includes a frame and a plurality of quick release couplings. The quick release couplings can depend from the frame in a two dimensional array. The plurality of quick release couplings can be configured to be releasably coupled to a concrete mat and remotely released therefrom via a control system. A method for placing concrete mats includes provision of the system having a frame and a plurality of quick release couplings. A lifting device can be provided. The system can be connected to the lifting device. A concrete mat can be connected to the quick release couplings of the system. The frame can be lowered to a predetermined depth where the concrete mat is adjacent to a floor of a body of water. The concrete mat can be released from the quick release couplings.
