QED SUBHUB - Tidal Platform

Subhub is a submersible, gravity based, foundation platform that supports every need of tidal turbines through life.

• Its unique ballasting system enables it to be self installing and self aligning with the flow
• It requires limited amount of support from commonly available tugs and barges
• Therefore only requires a single, quick offshore operation to install it making deployment an extremely low cost exercise
• Importantly it has high availability of marine operations because it has wide weather, wave and tidal windows.
• The hull form is carefully designed to accelerate the flow to extract the most energy from the site and overcome tidal shear
• Significant environmental benefits of no-noise installaiton with zero aesthetic impact on the seascape

• Low cost  deployment using harbour tugs
• Cheap to install and maintain
• Enhances tidal site yield by up to 48%
• Environmentally low impact on seascape and seabed and marine life
