Abstract


Dry docking is a common procedure for maritime vessels to enable necessary tasks including maintenance, inspection, and design changes. Since the world is becoming more dependent on renewable energy, the aim of this study is to develop a mathematical model to estimate hydropower generated from the filling process of graving docks. A thorough case study has been conducted with an emphasis on ASRY dry dock No. 1 in order to achieve this goal. By strategically placing hydroelectric turbines throughout the dry dock filling period and utilizing only the natural head difference between sea level and the dry dock level, the study aims to assess the viability and effectiveness of hydropower generation. The case results state that a cost saving of approximately 1 MW per intake line of the dock can be achieved which saves approximately 4572 kg of CO2 emissions for the whole operation that could have been released into the environment if this power is generated using natural gas.
