Description

(5) SHIP

The invention relates to shipbuilding, and more specifically to the design of ships, mainly ice navigation. A vessel, predominantly an ice-float, is known, having a stationary box-section piping made in the form of local strengthening of the hull in the current watering region using heat-transfer fluid to heat the outer skin of the hull of the cooling water of the main engine pumped by the cooling pump 1. The disadvantage of this vessel is significant energy consumption for the prevention of icing. The purpose of the invention is to reduce energy consumption for the prevention of icing. The goal is achieved by the fact that in the vessel the ballast compartments communicate with the pipeline fixed on the inside of the hull of the vessel hull and are connected through a stop valve to the suction port of the circulation circuit of the turbo generator cooling system, the discharge port of which is through the turbo generator condenser, stop valve and pipeline supply of coolant communicated with ballast compartments. The drawing shows the actual waterline of the vessel, a transverse section. The hull 1. contains a turbo-generator 2, a condenser 3 of the turbogenerator, a cooling pump, a discharge pipe 5 with valve 6, a manifold 7, side channels 8, a main pipeline 9, valves 10 for ballast tanks 11, a valve 12 for seawater intake and a valve 13 for cooled drain seawater, valves 1 for supplying seawater to the cooled pump and valve 15 for discharging water from ballast tanks.

The system functions as follows.

The outboard water, taken by the cooling pump t through the valve 12, is pumped and heated in the condenser 3 of the turbogenerator due to the heat of the condensed steam. Heated water through the pressure pipe 5 through valve 6 enters the collector. 7 and further into the side channels 8, located along the current waterline in places of the most intensive icing of the outer skin of the hull 1. The side channels 8 are made in the form of ducts, one of the shingles. which is the hull 1 of the vessel. The cooled outboard water through the main pipeline 9 through the valve 13 is diverted overboard.

To fill the ballast tanks 11, valves 10 are opened and valve 13 is closed. Valves 6 and 12 are open, and valves 15 and IV are closed.

In order to empty the ballast tanks, valves 10, I and 15 open, and valves 6 and 13 close.

The present invention does not require additional costs for installation of equipment or for fuel.

The annual economic effect from the use of the proposed invention is 970 thousand rubles.
