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.

Powering and resistance

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.

Resistance

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

Using Holtrop Method

Another Method

Power Calculation

At speed 21 knots it gives:

Resistance = 664.37 KNPower = 13956.879 KW

• EHP = R * V

• QPC = EHP/DHP

• BHP = DHP/( shaft * GB )
