The article considers a way to improve the efficiency of ship transformers. A temperature control system is used. In the process of changing the voltage in the ship's system, thermal losses of copper in the iron core and coil usually often occur. Thus, overloading will cause excessive heating and may affect the operation of the transformer. The calculation of the thermal parameters of the transformer is given. The mathematical model in Matlab is shown. The article proposes a functional diagram of the device. The control system monitors the temperature inside the transformer when operating under overload conditions. It is shown that the installation of the device will improve the performance o f the transformer and save its service life

The article proposes the development of methods for compensating for distortions occurring when specifying the following types of forward-backward movement, swinging port-starboard, turning to port-starboard and their combinations. Uncompensated stops lead to uncontrolled turns of remote-controlled devices when setting any of the types of control. The controllability of underwater remote-controlled vehicles is associated with the limited field of view of the phototelevision complex in conditions of artificial lighting and a limited observation range, usually 5-7 meters. The developed technology can be used for various remote-controlled and autonomous mobile objects, the power plant of which is built on a multi-propulsion basis

The simulation of the working processes of the MAN D&T MC series marine diesel engine was carried out in order to reduce carbon dioxide emissions with exhaust gases. The purpose of the simulation was to find design and operational solutions that affect CO2 emissions. When performing a computational study, a mathematical model of a combined internal combustion engine implemented in the DIESEL-RK computer program was used. The studied variables are the compression ratio, the advance angle and the duration of fuel injection, the values of which can be set without making significant changes to the engine design. Mathematical models are obtained in the form of regression equations that describe the effect of the studied fuel supply parameters (compression ratio, fuel injection advance angle and fuel injection duration) on the target functions - specific carbon dioxide emission and effective power of the 6S60MC diesel engine. To determine the coefficients of the regression equation, planning of a complete factorial experiment of the second order is implemented. In order to find the minimum value of carbon dioxide emissions using the generalized reduced gradient method, the problem of choosing the optimal values of the compression ratio, fuel injection duration and fuel injection advance angle for a given effective power of a 6S60MC marine diesel engine is solved. It is shown that, for example, with an engine power of 10,000 kW, the reduction in carbon dioxide emissions by optimizing the specified fuel supply parameters will be 7.37%

To destabilize finely dispersed oil-water emulsions and, as a result, to increase the efficiency of flotation treatment of ship bilge water, a reagent treatment method is used. The limiting factors in choosing a flocculant for preliminary reagent treatment of bilge waters should include the physicochemical characteristics of the oilwater solution. The paper presents the results of a study of the following physicochemical parameters of a solution of ship's bilge waters: the dispersed composition of contaminants, the charge of contaminant particles, kinematic viscosity, density and surface tension of the solution
