The article considers the economic security of port enterprises, which is an integral part of the development of these enterprises, the basis for improving the quality and competitiveness of port services. The following main areas were identified, changes in which significantly affect the deve-lopment of maritime transport, and which must be taken into account in the formation and implementation of the national maritime policy of Ukraine and the development strategy of individual enterprises in the maritime sector. Having analyzed all types of functional components of the integrated safety system of maritime transport enterprises, and taking into account significant features in the specifics of indivi-dual facilities (ports, shipping companies and coastal enterprises), the proposed classification of water safety threats in terms of three major water transport facilities separately, exposed to threats and dangers: economic security of coastal facilities and shore personnel, navigable economic security, port economic security. The peculiarities of ensuring maritime safety are the presence of a list of threats associated with the specifics of the operational activities of maritime transport enterprises. Factors in the organization of economic security relate to the functionality of its organizational and institutional support. Most of the existing approaches to solving the issues of economic security of the enterprise allowed to choose the most optimal set of principles of management of the economic security system: the principle of complexity, the principle of confidentiality provides, the principle of coordination and coherence of the enterprise. This study focuses on economic levers that are directly related to tracking and eliminating threats. Economic methods direct the implementation of the mechanism to reduce resource consumption, increase the profile and efficiency. Thus, increasing the profile is due to additional profits, reducing resource intensity − by optimizing resources and reducing costs when moving from a lower level of economic security profile to higher, efficiency increases when reducing resource intensity, as well as by increasing effects. Having analyzed all types of functional components of the integrated security system of maritime transport enterprises, and taking into account significant features in the specifics of individual facilities (ports, shipping companies and coastal enterprises), we propose to consider the classification of water transport security threats in terms of three major water transport facilities separately exposed to threats and dangers: economic security of coastal facilities and shore personnel, navigable economic security, port economic security. Thus, the peculiarities of maritime safety are the presence of a list of threats associated with the specifics of the operational activities of maritime transport enterprises. Factors in the organization of economic security relate to the functionality of its organizational and institutional support. The implementation of economic security requires from the maritime industry such qualities as reliability, flexibility and quality. These enterprises are becoming part of the system, which as a whole is a subject of competition, therefore, to ensure the competitiveness of the whole system, the enterprises of the maritime industry must provide an increasing range of services.
