UNDERWATER CABLE LAYING METHOD Russian patent published in 2006 - IPC H02G1/10 

FIELD: laying electric service lines across water obstacles.

SUBSTANCE: proposed method involves cable laying in plastic pipeline. To this end plastic pipes are first welded together on land with cable and ground wire or wires gradually drawn through them; then pipeline incorporating cable and ground wire or wires is pushed to water and conveyed toward transition point on bank. Pipe is secured on bank for movement and transported to opposite laying point with reference to pre-installed buoys at the same time arranging it on underwater route. Upon fixation of other end of pipe for displacement this pipe is unsealed for water admission therein, gradually laid on bottom, and secured thereon.

EFFECT: reduced anthropogenic impact time, ability of protecting underwater communities of water reservoir.
