1. Subdivision and watertight integrity: - The purpose of transverse bulkheads, the construction of a watertight bulkhead, its attachment to sides, deck and tank top and how water-tightness is maintained where bulkheads are pierced by pipes, frames and doorways. - Distinguish between watertight, non-watertight, collision and oil tight or tank bulkheads. Define margin line, bulkhead deck and weathertight. - Requirements regarding: *The positioning and heights of bulkheads in respect of forepeak, after peak, engine spaces and length. *Penetrations of the collision bulkhead. *The closing of watertight doors. *The position of hinged watertight doors, side scuttles above the deepest subdivision load line. *Drills, inspections and tests of watertight doors, side scuttles, valves and other closing mechanisms. - Maintenance of water tightness below the tank top in line with the bulkhead. - Testing of bulkheads for tightness. - Purpose of wash bulkheads in deep tanks. - Internal stresses resulting from the cargo and external stresses in a seaway.
