FIELD: shipbuilding.

SUBSTANCE: collective rescue vehicle for use in ice conditions comprises a body, a propulsion system with a rotary screw propulsion unit and a power plant, electrical equipment, a ventilation and heating system, release and towing devices. There is an electric propulsion system connected to the power plant. The power plant is hybrid and includes a main engine located in the engine room and an energy source connected in the combustion zone without the use of air supply. The hull includes a compartmentalized displacement lower structure with a stem cut at an angle in the underwater part and a superstructure located on it, made of fire-resistant material with a frame and divided into an engine room and a salon. The propulsion system additionally includes an auxiliary tracked propulsion unit located along the stem. Auxiliary tracked and rotary-screw propulsors are connected to elements of the electric propulsion system.

EFFECT: safety, reliability, manoeuvrability and autonomy are increased.
