What does the term "double hull" mean concerning tankers?

• A. A single layer of hull for lightness
• B. A hull design with two layers of watertight surface
• C. A design that aids in faster navigation
• D. A hull made entirely of reinforced steel

Answer: (B)

The term "double hull" refers to a hull design that incorporates two layers of watertight surface. This design is particularly important for tankers, as it significantly enhances safety and environmental protection. The inner hull serves as a primary barrier against oil spills and leaks, while the outer hull provides an additional layer of security. In the event of a collision or grounding, if the outer hull is breached, the inner hull can still prevent the loss of cargo, thereby reducing the risk of environmental contamination. Double hull designs are a regulatory requirement for many modern tankers, particularly those that transport oil, as they mitigate the risk of pollution and improve the structural integrity of the vessel. This innovation provides enhanced safety on the water, which is crucial given the potential consequences of spills and environmental damage.
