“…An increase to 12 knots causes the EEDI value to exceed the required limit. Tokuslu stated that EEDI performance can be improved by reducing speed, increasing dead weight tonnage, and technological intervention [22], By lowering the speed from 12 knots to 9 knots, there is a significant decrease in EEDI of 66%, while lowering the speed from 12 knots to 6 knots, there is a decrease of 86.6%.…”

Currently, efforts are focused on reducing emissions to support carbon neutrality by 2050 through green technology. Green technology applies to the ship's design, port, engine selection, fuel, and operation. This study modified the hull to reduce drag and improve fuel efficiency. Changes were made based on variations in the deadrise angle, which were analyzed using numerical simulation. In the current situation, the deadrise angle is changed from 9° to 10°, 15°, and 20°. On the angle variation, the effects of changes in ship drag, fuel, and energy efficiency design index were analyzed (EEDI). The method simulates computational fluid dynamics with a Holtrop calculation method validation approach. At 12 and 6 knots above the current deadrise, resistance is reduced by 8.2% and 6.8%, respectively. The fuel efficiency achieved is 6.9% at 6 knots and 8.2% at 12 knots, resulting in monthly fuel savings of 2.43 tonnes. Furthermore, the phenomenon of the EEDI value at the lowest resistance and highest speed has a decreased performance value. Reducing the speed from 12 to 9 knots improves the performance of EEDI by 66%

“…Corbett et al [8] analysed the mortality that was caused by emissions. Cohen et al [9], Cofala et al, [10], Wang et al [11], Deniz and Kilic [12], EEA, 2013, Viana et al [13], Bayirhan et al [14], and Tokuslu [15] made studies on these subjects and these studies have emphasized that ship-borne air emissions have harmful impacts on human health and environment and concrete measures should be taken to reduce its` effects. Nevertheless, Kesgin and Vardar [16] published a specific paper about exhaust gas emissions in the staraits of Turkey in 2001.…”

Canakkale Strait (Dardanelles), is one of two straits that have Turkey with Bosphorus. This strait, which has a length of 38 miles, provides the connection of countries with a coast to the Black Sea to the Mediterranean. 43454 ships pass through the strait annually. According to 2019 data, 45.33% general cargo ship, 21.43% bulk carrier, 21.78% tanker, 6.43% container, 0.65% roro, and 0.61% passenger ship, and 3.77% other type of ship passed. Therefore, by including the Canakkale 1915 bridge which will be completed in 2023, the six most frequent ship types were examined and their emission values were calculated in this study.

“…A large and growing body of literature has investigated ship emissions. There is a consensus among scientists that ambient concentrations of particulate matter (PM) and SO x have negative health impacts, including asthma, heart attacks, hospital admissions, and premature mortality [3][4][5][6][7][8][9][10][11][12].…”

The Istanbul Strait is one of the choke points in the international maritime trade. 44868 ships have passed through the Istanbul Strait in the last two years. These merchant ships are emitting exhaust gas emissions such as CO2, NOx, SOx inten?sively. These pollutants also affect human health and the environment. There is a consensus among scientists that ambient concentrations of particulate matter and SOx have negative health impacts, including asthma, heart attacks, hospital admissions, and premature mortality. In this study, the exhaust gas emissions from ships are estimated based on real ship movements, and analyses are made accord?ing to the reduction from 3.5-0.5% of the allowed sulphur content of the fuel was implemented on January 1, 2020. Firstly, Annex four which is containing the reg?ulations imposed by the International Maritime Organization was examined, and also SOx emission which is caused by ships passing through the Istanbul Strait was investigated. Also, a new approach to Trozzi and Vaccaro methodology was built. After, emission projections for 2030 and 2040 were made and the rate of SOx and particulate matter were analysed.
