double hull

A double hull is a ship design featuring two layers of hull around the cargo area, instead of just one. This construction provides extra protection by reducing the risk of leaks or spills if the outer hull is damaged, making it safer for the environment and the vessel. Double hulls are commonly used in tankers and large ships to prevent oil spills and improve durability. Essentially, it’s like having a backup barrier; if the outer shell is breached, the inner one still contains the cargo, enhancing safety and environmental protection.
