Subject Area
Den Yachthafen von Hamburg, bei Wedel an der Unterelbe, passieren u. a. große Containerschiffe, die mit ihren Bug- und Heckwellen die Yachten in ihren Liegeplätzen beeinflussen. In der Dienststelle Hamburg der Bundesanstalt für Wasserbau baute man ein maßstäbliches Ausschnittsmodell der Elbe und des Yachthafens. Hier werden bei Einzelfahrten und bei Begegnungsfahrten der Wasserstand, die Wellenhöhe und -ausbreitung dreidimensional erfasst und ausgewertet. Exakte Messmethoden ergaben, dass neben einer Reduzierung der Schiffsgeschwindigkeit eine Linienmole vor der Hafeneinfahrt eine bauliche Variante ist, um schiffserzeugte Strömungen und Wellenhöhen im Hafenbereich zu reduzieren.
Big container ships pass the marina of Hamburg, situated close to Wedel at the lower River Elbe, and affect the moored yachts with their bow and tail waves. A scale model of the River Elbe and the Hamburg marina was built up in the Hamburg office of the BAW. Water level, wave height and wave propagation during individual trips and encounters are measured in three dimensions and are analysed. A line jetty in front of the harbour entrance is a possible structural modification - as precise measuring methods showed - used in addition to a reduction of the ships' speed.

Hamburg's marina, close to Wedel on the lower Elbe. Large container ships plying the Elbe create bow and stern waves, which impact on the moored yachts.
How can this impact be minimized? The Hamburg office of the BAW houses this scale model of the River Elbe in the wave tank measuring 100 x 35 metres. The maximum water depth of the tank is 0.7 metres.
The marina and model ships are on a scale of 1:40.
Everything is ready for the experiment and the ship's test run can begin.
Water level, wave height and
wave propagation during both individual trips and encounter trips are measured in three dimensions and analysed. The ship's movements are
recorded contact-free. The current position
of the ship is also continually registered. The aim is
to reduce the current in the harbour entrance by means of wave transformation and the effects of superimposition of the long-periodic waves. A line jetty
has been built in front of the marina as a means of reducing currents and wave heights in the harbour area.
Tracers are added to help analyse the flow behaviour.
The strength of the flow between the line jetty and the harbour entrance is made visible by the
tracers and recorded. The water level is ascertained by resistance
measurements. The ships movements are
measured by these 3-D rotation lasers. All the data merge
in the measuring container, where they're processed and analysed.
The findings of the model experiment are presented in a report. One possibility examined, the line jetty - represented by the green line - was the most effective in reducing the flow velocity produced by passing ships in the harbour entrance. This then could be the solution of the marina's problem.
