The seafarers carried out the professional activity in a complex electromagnetic environment (EME), with technical means, structural materials, depending on the purpose of the watercraft, architectural features, and vessel classification. There are static electric fields, permanent magnetic and low-frequency electric and magnetic fields on ships. Marine radio-electronic means (REM) creates Electromagnetic fields (EMF) of the radio frequency range that provide communication, the safety of navigation and operation, and solving navigation problems. According to the documents of the sanitary legislation, specialists carry out control of the maximum permissible EMF levels for watercraft and marine structures at the design stage of the vessel by calculating the intensity of electromagnetic fields during commissioning, instrumental control of EMF levels. There are new technical means in modern automated vessels of various types and purposes that create electromagnetic fields in the crew's stay zones, which makes it urgent to improve regulatory and methodological documents in the area of ensuring the electromagnetic safety of the team and passengers. The study aims to develop proposals for regulatory, methodological, and hardware control over compliance with the maximum permissible levels of electromagnetic fields on ships to ensure the electromagnetic safety of the crew. Generalization of materials of own research of EME on ships, systematization of sources of electromagnetic fields. Analysis of regulations in occupational safety and health for the protection of the crew from the effects of EME, methodological documents on the calculation forecasting, and instrumental determination of the levels of electromagnetic fields. Experts have revealed that there are electromagnetic fields of a wide frequency range in the premises of ships and on open decks. The study showed that electromagnetic fields of a wide frequency range are created in the premises of ships and on open decks. Indoors, the most significant is the impact on the crew of electric and magnetic fields with a frequency of 50 Hz created by the ship's electric power systems. In addition, on open decks (at workplaces and in crew recreation areas), the protection of the crew from EMF antennas of the radio frequency range is relevant. Therefore, it is necessary to develop methods for calculating the prediction of EMF levels and improve the means of measuring electromagnetic fields on ships. The most common sources of EMF in the crew's stay areas are radio communication and radar facilities, ship's electric power systems. The task of developing a methodological document on the calculated prediction of EMF levels in rooms and on open decks at the design stage of ships is urgent. In addition, it is necessary to develop devices-meters of electromagnetic fields for instrumental monitoring of EMF levels in actual operating conditions of the vessel.

The establishment of smart grids requires special attention to the safety of power industry facilities and the reduction in their negative impact on personnel and the environment. A significant factor of such an impact is the considerable intensities of electromagnetic field (EMF) generated by such facilities. In the context of power industry digitalization, the development of methods and tools for EMF digital simulation is needed to ensure the electromagnetic safety of the service personnel. Computer models designed to adequately determine the EMF generated by overhead power lines (OPL) can be implemented based on the methods and tools created to determine operating parameters of electric power systems in phase coordinates developed at Irkutsk State Transport University. The technique of electromagnetic safety analysis is implemented based on the proposed approach and has the following features: a systems approach, which is the possibility of simulating electromagnetic fields in terms of properties and characteristics of a complex electric power system; versatility, which allows simulating power lines and traction networks of various designs; appropriateness to the environment achieved by considering the profile of the underlying surface, underground utilities, and artificial structures of rail transport, such as galleries, bridges, and tunnels; comprehensiveness, which is provided by combining the computation of operating parameters and the determination of EMF intensities. The paper describes methods and algorithms developed to determine the intensities of electromagnetic fields generated by multi-conductor power lines at fundamental and higher harmonics frequencies. A technique for the EMF determination at the points of OPL orthogonal crossing is also presented.
