Unavailable from October 1 ,2006 to February 2,2007 because of construction work. We appreciate your understanding.

This tank is provided with ferro-concrete walls, one side of which has five one-meter square viewing windows for observing underwater motions of the experimental model.
Dimensions：40m (length) ×4m (width) ×2m (depth)

This wave generator consists of eight segmented wave generator plates, whose cyclic motions can produce rhythmic or arrhythmic waves of various wave heights and wavelengths. Wave reflections off the wave generator plates are kept to a minimum. Control of absorption permits longer run times.

Item	Explanation
Model	Flap servomotor, timing belt drive
Wave height	max. 0.2m (frequency 1.1 〜1.5sec)
Period of waves	0.5〜4.0sec
Wave generator plates	SUS, 0.5m (width) × 8plates

　

The gauge trolley slides over the tank. A variety of models can be attached to the trolley. Running the trolley at different speeds allows monitoring and analysis of characteristics such as water resistance to various motions.

Item	Explanation
Model	Analog uniaxial two-wheel drive
Speed	0.2〜2.0m/s
Acceleration rate	within ± 3％ F･S

This beach-type wave absorber comprises a slope with a sponge-type absorber surface.

1) Tests of flow and wave effects on various marine structure models
