Electromagnetic safety of modern marine facilities
Object and purpose of research. This paper discusses electromagnetic safety of various marine facilities (ships, vessels, floating structures, etc.). The purpose of this study is to develop methodology for ensuring their electromagnetic safety in standard operational conditions. Materials and methods. Electromagnetic safety technology suggested in this paper is justified by investigation of modern ships as the most complex marine technical objects. This study shows that suggested technologies are preferable to implement by means of experimental assessment methods, because these methods take into account real configuration, structure and other specifics of ship equipment and structures. Main results. This study shows that investigation of ship, its equipment and complement as a single integrated system makes it possible to ensure electromagnetic safety of ship against internal and external effects, within the framework of unified protection methodology. The technology suggested in this paper ensures electromagnetic compatibility of equipment aboard modern ships, as well as protects them and their crews against strong electromagnetic attacks. This technology is based on scientific & technical support of activities in this field over the whole life cycle of ship, including design, construction, development and delivery of equipment, acceptance testing and operation. The paper also justifies development concept and performance parameters of special test facilities intended for practical implementation of this technology. Conclusion. Technology of electromagnetic safety aboard ships suggested in this paper makes in possible, in certain verified cases, to do without unconditional strict requirements to the equipment delivered to the ship, by means of optimal combination of protective tools and measures developed and implemented by designers of ship and her equipment. Test equipment developed under this concept makes it possible to test equipment together with its cables and wiring in laboratory and real conditions, as well at the test beds of equipment developers and, apart from it, assess efficiency and sufficiency of implemented protective measures and tools. Test equipment reliably simulates main types of strong electromagnetic attacks of various physical natures, including electromagnetic pulses of nuclear explosions.
