Deploying Our Renewable Obligation

Subhub installed at Flowave TT prior to turbine performance trials.

Subhub aims to reduce the cost of deployment of tidal turbines by installing an array of tidal turbines in a single offshore operation using small, low cost support vessels. It also:

  • Commissions and tests all systems ashore;
  • Transports a fully integrated array of turbines to an offshore site;
  • Uses a single dry mate connector link 3 turbines;
  • Installs the turbines ready for service within safe operational limits of 1 tidal cycle;
  • Secures the turbines to the seabed during operation using a gravity based system;
  • Significantly increases the power output by accelerating the flow into the turbines;
  • Reduces the velocity shear profile between the top & bottom of the rotor;
  • Retrieves the turbines to the surface for maintenance or removal with a simple ballasting procedure.
