From the old sailing ships (that were dependent on wind and currents) to today’s ships with highly sophisticated engines, Marine propulsion systems have changed radically over the years. In this section, we study the varous types of marine propulsion.

• Sailing ships
• Steamships
• Modern steamships
• The change from steamships to motorships over the years
• Diesel-electric propulsion system
  • Azipods
  • Dynamic Positioning System (DPS)
  • Multi-Directional Propulsion
• Nuclear Power in Ships
• Recent Developments in Marine Propulsion
