Due to various stresses acting. Like
Regional Stresses affecting Bulk Carriers
Care to be taken always while loading and continuous monitoring for hogging and sagging. Sagging comes in the areas where more weight and hogging comes in the area of less weight. Uneven distribution of weight could lead the ship breaking into two. However even after loading to even keel still the vessel experiences this problem due to the waves. During rough weather extra care to be taken as the high raising waves provides extra buoyancy.
Transverse Stress: These are caused due to force exerted from cargo or structural weights or motion in sea way which in turn affects the ships cross sectional area.
Racking: Rolling causes ship’s deck to move laterally when compared to bottom thereby causing the side shells to move vertically relative to each other
