What are cofferdams used for in damage control?

Cofferdams are temporary structures that are primarily employed in damage control operations to create a dry work environment, particularly in damaged areas of a vessel. By constructing cofferdams around the compromised section, water can be held back, allowing for repairs to be made without the interference of flooding. This is crucial in addressing hull breaches or any failure in the watertight integrity of the vessel.

By effectively isolating the damaged area, cofferdams provide a stable platform for building additional bulkheads, which can reinforce structural integrity and help secure the damaged section. This method is essential for preventing further flooding and controlling the damage, thus ensuring the safety and stability of the ship while repairs are being conducted. The use of cofferdams significantly enhances the efficiency and safety of damage control measures in maritime operations.
