POWER PLANT OF A FISHING VESSEL Russian patent published in 2022 - IPC B63H23/12 

FIELD: shipbuilding.

SUBSTANCE: invention relates to the field of shipbuilding and relates to the design of the power plant of a fishing vessel with a single AC power plant. The power plant of a fishing vessel contains two controllable pitch propeller drive systems: a mechanical one, including a shaft line, a gearbox with a thrust bearing, a supercharged main engine; electric, including a shaft generator connected to the network of a single ship power plant, consisting of a gas turbine generator with a regenerator. The air coming from the gas turbine generator compressor is supplied through the control valves, respectively, to the air manifold of the main engine and to the combustion chamber of the gas turbine generator through the regenerator, and the exhaust gases from the exhaust manifold through the check valve are fed into the combustion chamber of the gas turbine generator. The main engine operates according to the load characteristic, the shaft generator is used of a synchronous type - the generator / engine, the main engine, the shaft generator are connected to the gearbox using electromagnetic clutches, and the shaft line is connected to the gearbox by means of a friction clutch built into the gearbox gear. The power of the main engine must be not less than the power of the main engine during the economic course of the ship, and the power of the shaft generator and gas turbine generator must be equal, respectively, to the power of the ship's power plant.

EFFECT: increase the efficiency of the power plant and reduce dimensions and weight of the power plant.
