Abstract:

Air pollution from shipping is a critical issue, especially in dense ports. One of the proposed technologies to reduce ship emissions in ports is the Onshore Power Supply (OPS) system, where ships turn off their auxiliary electric generator engines and connect into the port grid. Several studies were conducted in European and USA ports. This study tackles the application of the OPS in the port of Alexandria, in line with Egypt’s Vision 2030 concerning the issue of climate change. The study focuses on analyzing the ships data collected from Alexandria port along one month. The present investigation aiming to conduct a comprehensive socio-economic and cost effectiveness analyses of OPS. To enhance the environmental potential of OPS, deploying four solar energy scenarios as the OPS electricity source is proposed.

The results revealed that relying on the national grid decreases emissions by 27.5%, and it is predicted to reach 100% if the electricity is generated from solar energy. Also, the economic analysis shows good profitability with a payback period of almost two years. Therefore, the implementation of the solar-powered OPS system in Alexandria port not only contributes to improving the air quality in the area, but also enhancing the country’s environmental, social and economic goals. Improving port infrastructure and using clean energy technologies can significantly enhance the quality of life in port cities and promote sustainable development.

Abstract:

This Paper investigates geomagnetic polarity reversals and how they may affect ships safety of navigation as well as investigates the dangers that are posed with the geomagnetic disturbances.

This activity involves focusing on the impacts of particular disturbances on vital navigation systems like GNSS (Global Navigation Satellite System), ECDIS (Electronic Chart Display & Information System), and even the compass. The paper analyzes the impacts of such events on oceanic voyages as well as assesses the use of conventional techniques during these situations and developing appropriate contingency plans for the safe wet passage.

The methodology followed a mixed methods approach, which included a questionnaire, which was sent to foreign and Egyptian maritime professionals (shipmasters, navigators, and instructors); this was done in an attempt to gauge the industry awareness and preparedness. In addition, it is felt that the current levels of preparedness are inadequate for the potential alterations that may occur.

The study contributes novel insights into the specific technological vulnerabilities and operational challenges posed by geomagnetic reversals, offering actionable recommendations for improving navigational reliability for facing magnetic disturbances.

The primary results reveal major deficits in knowledge related to influences of geomagnetic polarity reversal on navigation systems as more than 60 % of respondents have a poor understanding. The results show that the world really need to plan for research on these issues. The findings highlight the urgent need for investment in targeted education and training programs, the development and implementation of robust alternative navigation systems, and enhanced international collaboration to build resilience within the maritime industry.
