This paper aims to present an innovative approach to maritime transportation solutions and the need to minimize gas emissions and fuel consumption through green hydrogen research and substitution. Given its critical role in global commerce, maritime transportation has been a key factor for the past decades, specifically regarding the optimization of ship routing. The traditional focus on minimizing distance has been supplemented with modern, sustainability-driven objectives, including greater attention to fuel con...

Sulina channel is one of the three arms of the Danube, through which the river outflows into the Black Sea. At the same time, this is an important navigation waterway, since it is the main entrance from the Black Sea in the seventh Pan-European transportation corridor, represented by the Maine-Rhine-Danube navigation system. Hence, high navigation traffic is noticed, which was significantly increased in the last years. On the other hand, this area often faces severe weather conditions with high gradients in the en...

The transition to a sustainable energy system is one of the European Union's key strategic directions, in line with achieving climate neutrality by 2050, as outlined by the European Green Deal. The Black Sea region has considerable potential for renewable energy sources, particularly offshore wind, solar, and biomass. Due to this potential, the area has become a hub for European initiatives focused on increasing the share of renewable sources in the regional energy mix, and consequently, on energy security and red...

The accurate assessment of a ship-s dynamic behavior is essential for understanding its stability characteristics, particularly in response to free oscillations such as roll decay. This study presents the development and application of a compact, cost-effective inertial measurement system based on the Bosch BMX160 IMU sensor, integrated with a Raspberry Pi 4 single-board computer, for measuring ship model free oscillations both in water and in a controlled air environment. The system enables remote data acquisitio...

Catamarans are widely used in marine transport due to their advantages in stability and speed. However, their hydrodynamic performance is affected by the interaction between the two hulls, which creates complex interference phenomena influencing resistance and fuel consumption. Understanding and quantifying these interference effects is essential for optimizing catamaran, a key factor not only for operational efficiency and emissions reduction but also for achieving climate-resilient, energy-efficient marine trans...
