Main Dimensions:
Length btw. PP 333,44 m
Breadth 42,8 m
Depth, to upper deck 27,3 m
Draught, summer 14,5 m
Speed 24,25 kn
Power 68656 kW
Key elements: Between half December and the end of March the complete structure has been reviewed. This was only possible in close cooperation with the Shipyard. Several meetings at the shipyard site, exchanging information and calculation results and discussing the findings, have taken place. Two offices of Bureau Veritas, Korea and Paris, have been working around the clock in order to make the deadlines of the shipyard.

In order to increase fatigue life,
compromise between:
- sufficient reinforcement
- smooth grinding
