title: Bulkhead Failure due to Flooded Holds

abstract: An important cause of bulk carrier loss is ingress of sea water owing to cracks in the side shell as a consequence of main frame deterioration and the subsequent failure of transverse bulkheads adjacent to the flooded hold. When the hold is flooded the stresses in the bulkhead are known to exceed yield and the bulkhead to have undergone slight distortion. The vertical bulkheads are corrugated and have upper support from cross deck strips. Typical initial damages are cracks in the joint between bulkhead corrugations and deck plating due partly to corrosion. These can lead to portions of the cross deck strip becoming detached from the bulkhead. Pressure on the ship sides can then cause the bulkhead and cross deck strip to buckle, with minor and local buckles on the bulkhead leading to shear buckling of the whole structure.

The purpose of the Study Group will be an investigation of this cracking and buckling process.
