This method utilises ROV (remotely operated underwater vehicle) technology to handle and place nodes at their pre-plotted positions. This type of deployment and recovery method uses a basket full of nodes which is lowered into the water. An ROV will connect with the compatible node basket and remove individual nodes from a tray in a pre-defined order. Each node will be placed on its allocated pre-plot position. On recovery, the process works in reverse; the node to be recovered is picked up by the ROV, placed into the node basket tray until the basket is full when it is lifted back to the surface. The basket is recovered onto the node vessel, the nodes are removed from the basket and reaped.
