FIELD: laying underwater cables. SUBSTANCE: laying of cable is effected by means of transport ship and that being transported; use is made of submarine and tender connected with it; tender is provided with cable compartment equipped with automatic control system for control of cable lowering and laying procedures; tender is provided with habitable compartment for splicing and checking the cable and automatic device for keeping the tender at preset distance from bottom by flooding the cable compartment with water as cable is consumed. Laying the cable is performed without surfacing of submarine. EFFECT: avoidance of effect of surrounding conditions, ice, swell; possibility of laying cable in any region of earth.
