The 24 paddle machine was installed in 1998 and was the first multi paddle, large flap Edinburgh Designs machine.
Having worked well for over 20 years, the servo amplifiers and digital controllers are now obsolete, and spares are hard to come by.
The machine is now like new and can be seen in action in the following video:
After 20 years, it was a good time for a full electronic upgrade.
The mechanical side of the machine only required some minor renewal works.
Edinburgh Designs have installed a highly unique piston wave tank in an autoclave at the Marin SLING Multiphase Laboratory.
The lab will be used to research the intricacies of the water-vapour boundary in sloshing waves.
The autoclave can vary the pressure (5 mbar to 10 bar), temperature (5°C to 200°C) and gas composition.
Due to the extreme environments, the tank and wavemaker are totally new for this prestigious project.
Edinburgh Designs have installed a new towing tank at the MTC College in Cairo, Egypt.
The tank features 8x700mm hinge depth absorbing flaps in a 50m long tank.
A towing carriage runs along the full lenght of the tank.
Edinburgh Designs have installed a 750mm piston tank at the University of Coventry.
The tank is 20m long, 750mm deep and 0.6m wide.
Sheffield University now have an Edinburgh Designs Double Ended Wave & Current Flume.
The tank has 2 x 0.7m Hinge Depth Force Feedback Absorbing Paddles: One on either end. Water depth is 1m and the sank side height is 1.3m.
The tank is designed for 0.8m/s Flow with an Ultrasonic Flow Measurement in the return pipe under the tank.
The brand new facility at MTU in Upstate Michigan features 8 x 0.7m hinge depth force feedback absorbing flaps in a concrete tank.
The tank has one glass side running the full length of the tank.
The beach is a custom curved profile with HDPE plastic decking.
The tank will be used for a wide variety of projects, from offshore controls studies to great lakes research.
Caen ESITC has opened a new marine test facility equipped with a 40 meter long Edinburgh Designs built flume tank.
The tank is 1m wide and 1.5m meters deep and features a 750mm piston wave generator.
Designed to accommodate physical modelling tests, the test tank is suitable for marine research and development work, coastal work studies, and port engineering research.
The project was funded by ESITC, the Normandy region, and public institutions CEREMA, DGPR and DGITM.
80X 0.7m hinge depth paddles at University College Cork.
This is one of four tanks that make up the specialist LIR NOTF Ocean Test Facility at the MaREI Center for Marine and Renewable Energy.
The tank is 25m x 18m x 1m deep and has a movable floor in its central section.
The floor can be raised above the surface of the tank to allow quick and easy model setup.
The floor can then be lowered to give a total of 2.4m depth. Two sides have ED designed slatted beaches made from recycled plastic.
Edinburgh Designs have commissioned a machine for a new low temperature at SINTEF in Norway.
The combined wave and flow tank was designed by SINTEF and is designed for oil-ice interaction studies.
We have built a bespoke current and wave tank for the Stony Brook University, New York State.
The tank can be seen in action on our Youtube page.
The tank features our first production Wet Back Piston Wavemaker. The machine is 25m long, 1.5m wide x 1.5m deep and is designed to operate in depths up to 1m.
The tank has glass sides to allow observation of experiments and stainless steel base trays.
The tank will be used for a wide variety of coastal engineering experiments.
