Corrosion as a Prime Cause of Oil Tanker Structural Failures: Casualty Analysis and Risk at Ballast Tank Boundaries and Transition Zones

Fatigue Cracks- Why They Occur, Where to Look, and Which Areas Need More Stringent Inspection

Limitations of Structural Surveys, Inspections, and Thickness Measurements in Assessing Corrosion and Diminution

Modes of structural failure

Pitting Corrosion

Reasons for Reduced Scantlings of Deck and Inner Bottom Plating of Oil Tankers in the Last Two Decades

Section Modulus

Thrust and center of pressure

1. Review of basics of stress and strain;
2. Simple bending theory, sectional modulus, their application to beams and ships.
3. Stresses in still water and in a seaway.
4. Murray’s method;
5. Shear force and bending moment curves of ship shapes;
6. Stress indicators:
7. Understanding deck strength calculations:
8. Loading of break bulk cargoes & project cargoes;
