A low-cost submersible platform for tidal sites
01.
Identification
The Subhub Tidal platform overcomes the high cost of installation and maintenance of tidal turbines, providing quick and reliable access to turbines and electrical infrastructure.
Subhub Tidal Platform is a submersible, gravity-based foundation used to support an array of tidal turbines through life. It integrates the whole tidal energy plant at the quayside, where everything is commissioned and tested in a safe, accessible environment. Subhub is then used as a transportation barge to deploy tidal equipment straight to site using commonly available, low cost, harbour tugs etc. In a single offshore operation the Subhub, along with turbines, is installed in a quick and easy ballasting process, using its unique submerged stability characteristics to install itself on the seabed. It then de-ballasts further to adopt its required operating condition. The hydrodynamically designed hull form accelerates flows to tidal turbines, to extract on average 47% more energy from sites. Maintenance and decommissioning is a simple case of deballasting Subhub to bring it back to the surface.
