4. Why containerization ?!
Increasing the efficiency of cargo handling,
reducing shipping time by 84% and costs by 35%.
Today, approximately 90% of non-bulk cargo
worldwide is transported by container.

5. Classification of container Ships

Data Collecting
Collecting data of many
ships to make regression
models to approximately
guess the parameters of
the new design.

14. Model Selection

15. From Autocad to Maxsurf

16.  Introduction
 Parametric study
 General arrangement
 Construction
 Powering and resistance

17. Hatchless Container Ships
• Deadweight can be increased by eliminating the weight of the heavy hatch covers.
• They are located high so their removal improves stability.
• Reducing time of port operations.
• Individual vertical stacks can be removed without disturbing the others.
• Securing of containers has become easier.
• The maintenance of hatch covers, coamings, gaskets, cleats etc., becomes unnecessary.

24. Resistance
Is the study of the forces opposed to
ship’s movement direction

25. Using Holtrop Method

26. Using Holtrop Method

27. Another Method

28. Power Calculation
At speed 21 knots it gives:
Resistance = 664.37 KN
Power = 13956.879 KW
• EHP = R * V
• QPC = EHP/DHP
• BHP = DHP/( shaft * GB )
