Detailed Design Assessment

“QED Naval can use its experience and sophisticated design tools from ANSYS to understand the physical limits and sensitivities that your system is exposed to during its operational life time”.

Profile of a standard monopile showing how the flow escapes around the turbine rotor.
This picture shows the streamlines, produced by ANSYS Fluent (CFD), for the tidal flow past and through a a standard monopile foundation mounted tidal turbine. It demonstates the blockage effects that the turbine has as the flow escapes around the top and sides of the turbine and foundation.

Advanced Numerical Modelling

We perform global and more detailed compartment based FEA stress analysis where the buckling characteristics of each panel of the vessel and strength can be assessed. Ultimately, the vessel life can be assessed using predictions of how it performs in a seaway by predicting the dynamic stress ranges.

We use the state of the art Computational Fluid Modelling (CFD) methods to predict vessel drag and lift coefficients and hence determine the propulsion requirements over a large range of velocities. Other practical features can be designed using these methods such as aligning bilge keels with the streamlines of the vessel reduce drag but significantly reduces roll amplitudes.

QED Naval has recently expanded its capabilities to include blade design using CFD methods to predict the thrust and torque characteristics of blades.

We also have expertise in design of turbines, matched with gearboxes and  and optimisation of the Power Take Off (PTO) systems for the turbines using MatLab and Simulink.

This picture shows a simple tidal turbin blade model mesh generated in ANSYS ICEM which could be ustilised to perform blade thrust, toque and power characteristics.
