Tinstrumentation. measurements and data flow 
The Federal German container vessel "Koln Atlantic" (callsign 
DAKE) was placed at our disposal as a measuring platform by 
Hapag-Lloyd AG (Fig. 2). The size of the vessel is 39 000 GRT 
(2600 TEU), the length is 240 m, and the speed is 21.5 knots 
but eventually depends upon the ship's schedule. On regular 
schedule in the North Atlantic service between Europe and the 
US East Coast and Canada the duration of a round trip is 28 
days. Port of Call in Germany is Bremerhaven, where the 
vessel is met regularly by DHI personnel.
