Because of strict environmental regulations, researchers are obligated to develop and apply alternative energy sources for ships. There are various possible alternatives for merchant ships. Fuel cells may be one of the alternatives with their fewer hazardous emissions. This study aims to investigate fuel cells' availability for merchant ships as an...

The maritime industry leading organization International Maritime Organization (IMO) is bringing more and more restrictive and effective rules on reducing greenhouse gas and air polluting emissions since the significant portion of the greenhouse gas emissions in the world are caused by commercial vessels. Therefore, an alternative energy source is...

Maritime transportation is the most efficient transportation type. Despite, maritime transportation is an effective way to transport goods and passengers, fossil fuels are still in use. Ammonia and hydrogen are promising alternative fuels for the complete decarbonization of maritime transportation with their zero-carbon content and they are also su...

Increasing environmental concerns are driving the shipping industry to take strict measures to deal with greenhouse gas emissions. International Maritime Organization drives the industry to find more efficient and environmentally friendly power systems. To mitigate harmful emissions, researches on marine alternative fuels, operational improvements...

Global warming and greenhouse gas emissions are today's major challenges for sustainable industrial developments, and shipping is an important key element of the industrial chain. However, maritime transportation is responsible for 3.1% of total CO 2 emissions worldwide, and International Maritime Organization estimates that it will continue to inc...

Shipping transportation is under the pressure of eliminating ship-sourced harmful emissions. In this perspective, alternative fuels and ecofriendly power generation technologies are gaining importance for sustainable shipping. Today, hydrogen as a fuel and fuel cells as power generation technology are under investigation by the maritime industry an...

The Çanakkale Strait is a difficult waterway with heavy commercial and local ship traffic. Also, the strait has great importance in environmental, historical, and economic perspectives. The 1915 Çanakkale Bridge is located in one of the riskiest parts of the strait in terms of navigational safety. In addition, since the bridge piers are located in...

In this study, measurable criteria that can affect the process of choosing four different tank coatings used today in chemical tankers have been determined, and the degree of impact and priority order of these criteria on the coating preference have been determined with the opinion of field experts. The criteria were determined by consulting the fi...

Zero-emission maritime transportation is the ultimate goal of the shipping industry. In this aim, new regulations lead to technical constraints which lead the naval industry toward efficient and environmentally friendly power and propulsion systems. Especially, minimizing the impacts of the ships operating in the coastal, harbor, or urban areas is...

The International Maritime Organization, the ruler of the maritime industry, aims to reduce ship-sourced emissions to cope with the greenhouse gas and pollutant emissions which are not only one of the main drivers of global warming but also have very serious harmful effects on human health, especially in cities with ports. In line with this objecti...

Decarbonization is under spotlights for shipping as with many other transportation units. However, the readiness and awareness of the Turkish maritime industry is a common uncertainty. To reveal and show the current progress of the industry, a survey has been carried out. Participants from different companies with different education levels and exp...

The typical negative effects of prolonged slow steaming operations are investigated in this study. The scope of the research is to examine the effects of the carbon deposit formation on piston rings (lack of sealing function), exhaust boiler (reduction in the heat recovery capacity), turbocharger (lack of scavenging capacity), and injector, due to...

Shipping is the most energy-efficient way for the transportation of goods and it has a substantial role in the global economy. The vast majority of the ships are addicted to fossil fuels as an energy source due to economic advantages, strong bunkering nets, and well-experienced operations of marine diesel engines. However, environmental concerns dr...

The study investigates marine engineering education on alternative fuels and hybrid propulsion regarding decarbonisation of shipping. A new course is proposed for maritime education and training subject to the IGF Code amendments to the STCW which lasts 14 weeks and 3 h per week. Competences at the STCW amendments for the persons who work on altern...

Maritime transportation is under the pressure of reducing greenhouse gas emissions from ships. The rule-maker of the maritime industry, International Maritime Organization tightens the bond around ships to eliminate harmful exhaust emissions due to environmental concerns. Considering chemical properties, the use of hydrogen in ships may be a soluti...

Since sea transportation is one of the sources of air pollution and greenhouse gas emissions, so restrictive regulations are entering into force by the International Maritime Organisation to cope with the ship sourced emissions. Alternative energy generating systems are one of the key concepts and fuel cells can be one of the solutions for the futu...
