Marine architects consider several factors when selecting a propulsion fuel for a marine vessel, including:
1. Cost: The cost of fuel is a significant factor in determining the type of fuel used. Marine architects consider the initial cost of the fuel as well as its long-term price stability.
2. Availability: The availability of fuel is another important consideration. The availability of fuel may be restricted by the geography of the voyage, the distance from the nearest port, and the regulations related to the type of fuel that can be used in that area.
3. Environmental impact: The environmental impact of the fuel is a critical criterion for selection. Many countries have imposed regulations to reduce emissions of greenhouse gases, such as carbon dioxide, and other pollutants from marine fuels. Architects need to consider the policies and regulations of the countries the vessel will navigate to comply with the legislation.
4. Performance: The fuel's performance is essential in choosing the right option. The power, speed, and range of the vessel depend on the fuel. Architects evaluate the efficiency, energy content, and specific consumption of the fuel.
5. Engine Compatibility: The fuel type must be compatible with the vessel's engine. Architects evaluate the characteristics of the engine to ensure that it can operate effectively with the selected fuel.
After considering these factors, marine architects choose between diesel, natural gas, liquefied natural (LNG), methanol, hydrogen or hybrid propulsion for each specific vessel.
