The visible effects of mucilage on the marine environment, fishing activities and human health need to be investigated, as well as the effects on ships that are invisible but involve great risks, and appropriate measures need to be taken. For this reason, the aim of the project is to investigate the socio-economic effects of mucilage on ship machinery systems and to conduct a risk assessment. It is aimed to examine the short, medium and long-term effects of this environmental event in the said regions and to create a guide for ships and maritime authorities to raise awareness and prevent other similar marine pollution.
Carrying out maintenance applications in the engine rooms of ships more effectively thanks to today's technological developments is a way to increase energy efficiency in marine vehicles. Thanks to the innovative maintenance approaches that will be adopted for the trouble-free operation of the systems, it is possible to reduce the frequency and severity of equipment failures, to save on maintenance costs and to extend the life of the equipment. Within the scope of this project, a study will be carried out to increase the efficiency of system maintenance processes carried out in the engine room of different types of ships. In this sense, it will be investigated how the innovations in the field of maintenance within the scope of Industry 4.0 can be adapted to the maintenance practices carried out in the ship engine room. With the case studies to be carried out within the scope of the project, possible gains that may occur as a result of the adaptation of innovative methods will be determined. Predictive maintenance is the most up-to-date maintenance approach that has been frequently researched by researchers recently. Within the scope of this project, researches will be conducted on the applicability of the condition-based, risk-based and reliability-centered maintenance methods mentioned under this approach on ships. In this direction, it is aimed to develop efficiency-enhancing maintenance models with the development of machine learning algorithms. Although the subject presented in the project is a current research topic in the maritime sector, although there are a small number of postgraduate thesis conducted at the international level within the scope of the subject, they do not exist as far as is known in the national sense. Unlike the theses in which the subject of maintenance on ships is investigated at the national level, in this project and its doctoral thesis, on the basis of innovative methods, automation-dependent maintenance models that do not examine the human error factor, but that can be used in future semi- or fully autonomous ships will be studied. It will be pioneering work.
Container terminals, which are directly affected by the changing trade volume, aim to provide the fastest, most effective and reliable service thanks to the developing technological opportunities. In line with these purposes, surface technologies in the maritime sector appear with examples such as autonomous ships, e-navigation, satellite communication aids, while in port operations, they can be exemplified as cargo automation systems, port terminal software, and autonomous cargo equipment. Thanks to the aforementioned technologies and also as a result of the increasing trade volume, an increase is observed in the port business volume. In addition, container terminals, which have many risk factors, aim to minimize human errors and complete efficient operations with technological developments. For this reason, the analysis of the processes is of great importance. At the same time, it allows easy completion of operational analyzes with the technologies that have developed in data processing in recent years. Risk estimation modeling using machine learning methods will provide great convenience in this context. It is aimed to predict situations that may affect the operation and take necessary precautions by processing near miss/accident events and port operation data with pre-determined machine learning methods. In addition, it is of great importance to prevent the loss of life and property that may occur as a result of accidents that may occur in container terminal operations with these methods. With this project, the analyzes of the ports will be made with machine learning methods and the risk factors will be determined. In addition, it is aimed to provide a useful study by making it available to the container terminals serving in Turkey.
