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?
Baltic CS 5600 Panmax Compact
“Typical” Post Panamax Ship of 5500 TEUL = 262 m, B = 40 m
Maersk Sealand – 6.200 TEU – 20005500 TEU Type lengthened for COSTAMARE
Post Panamax Ship 7500 TEUL = 320 m, B = 42,8 m
Colombo Express335 m Length – 14,5 m Draught – 42,8 m Breadth
60,5 m Air draft - 108.000 tdw
Anna Maersk352,18 m Length - 15 m Draught - 42,8 m Breadth

Korea: Cost of Hull, M/E, Electric, Outfitting
55% of the production cost belongs to the main engine
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
response (OCTOPUS)• Monitoring of ship specific
response parameters• Display of results on the bridge
