Reference Answer
### Concept
A bulk carrier is designed to carry unpackaged bulk cargo, such as grains, coal, and ore, in large cargo holds. The midship section represents the typical cross-section of the vessel in the cargo-carrying region, where longitudinal bending stresses are at their maximum. The structural design of this section is critical for the vessel's overall strength, integrity, and safety. A single-hull bulk carrier has a single layer of plating forming the sides of the cargo holds, making it vulnerable to side damage and corrosion from cargo and ballast water.
The key design features of a bulk carrier's midship section are driven by the need for:
1. **Longitudinal Strength:** To withstand hogging and sagging bending moments.
