TEU = Twenty feet Equal Unit6,058 x 2,438 x 2,591

20´ = 6,058 m

Converted T2-Tanker for Container Transport, Sea-Land Inc.

In 1968: 1st Generation 700 TEU at 20 knots

In 1972: 3rd Generation 3000 TEU at 26 knots

• High freeboard• Only 35% containers on deck

Modern Panamax Container Ship up to 5050 TEU• More stowage capacity by widening the decks at the ends • about 50% containers on deck

Close to 60% of containers are stowed on deck

How well can you see from the bridge?

Main Engine for 8200 TEU Container ShipsMax. power: 68,650 kW / 93,360 PS

Fuel consumption: 230 t/day at 25 kn

Top-Level of theWorlds Powerful Diesel Engine

• running time betweenmaintenance:20.000 working hour

• running condition85 to 90% of MCR

• Comparsion with car: 1.5 Mio. km with150km/h

12 Cylinder engine: bed with crank-shaft

• 12 Cylinder MAN / B&W: 24,6 m bed-plate with160 t crank-shaft

• 68 650 kW (93 360 PS)• shortage is the most serious

problem when ordering large container ships

Number of 40´bays at each Cargo HoldCase: two 40´bays

- Higher Flexible Loading - Larger structural strength(reefer / dangerous good)

Number of 40´bays at each Cargo HoldCase: three 40´bays

- Larger Heeling Tank - Less steel weight

Parametric Roll

• Heavy rolling in following seas

• Known since 3rd generation container ships

• Large container ships: danger of excessive rolling also in head seas

• Rolling angles of 50° and more have been reported

Overloaded Container Columns

Overloaded Container Fittings

• Seaway measured using the nautical X-band radar

• Hydrodynamic database• Mass information from loading

computer• Onboard calculation of ship
