### (a) Advantages of Corrugated Bulkheads
Corrugated bulkheads are constructed from plates that are pressed into a corrugated or troughed shape. This design provides the necessary stiffness to withstand lateral pressure without the need for welded stiffeners. The primary advantages of this construction method over a conventional plane bulkhead with stiffeners are:
1. **Reduction in Steel Weight:** The elimination of numerous vertical and horizontal stiffeners results in a significant saving in the overall steel weight of the bulkhead. This reduction in lightweight translates directly to an increase in the vessel's deadweight carrying capacity.
2. **Reduced Construction Costs:** The overall cost is reduced due to:
