Which Part addresses water-tight integrity?

• A. Part B-2
• B. Part B-1
• C. Part E
• D. Part C

Answer: (A)

Water-tight integrity is about keeping water from flooding from one area into another by maintaining effective watertight boundaries, such as bulkheads and doors, and ensuring they can be closed and sealed properly. The portion that specifically covers these requirements—how the hull and its compartments are kept watertight, the construction and condition of watertight doors, and the testing and maintenance of these boundaries—is Part B-2. That focus is essential for preventing progressive flooding and preserving buoyancy after damage, which is exactly what water-tight integrity is all about. The other sections address different safety topics and do not directly govern the structural barriers that keep water out of compartments, so they don’t address water-tight integrity in the same way.
