Ship design is the process of creating the structure and layout of a ship to ensure it is safe, efficient, and functional. Designers consider various factors, including the ship's purpose, size, and the materials used. They also focus on hydrodynamics, which is how the ship moves through water, to enhance performance and fuel efficiency. Additionally, ship design involves compliance with regulations and standards set by organizations like the International Maritime Organization (IMO). This ensures that ships are built to withstand harsh marine environments and meet safety requirements. Effective ship design ultimately contributes to the vessel's longevity and operational success.
