Subhub Appendages Arrive Ready for Commissioning and Testing

The recent arrival of the Subhub’s appendages brings the build phase of this fully integrated tidal platform to a conclusion. QED will soon validate claims that Subhub provides a “tidal array in a day” along with easy and quick recovery for maintenance at the surface or in sheltered water.

The Subhub is a universal foundation platform and deployment / recovery method suitable for any type of turbine. It can be modified to capture the benefits of both Horizontal Axis Turbines (HATs) and/or Vertical Axis Turbines (VATs). The platform’s ballasting methods can work equally well with wave turbines as well.

The principle benefit of the Subhub is its ability to install a fully integrated, gravity based structure to the seabed including turbines, PTO equipment, ballast. It does this in a single and quick offshore operation using small support vessels which are commonly available making it a very cost effective solution.

However, Subhub also provides large performance advantages by steering the turbulent flows into the turbines enabling them to perform as expected in rated flow conditions significantly increasing site capacity factors and energy yield.

Subhub with all her appendages including Cross Beam to support the tidal turbines and the Subsea Manifold in the background to control the Subhub remotely from small support vessel or barge.

Measurements being taken on the Cross Beam for the fairing structure to be added with the tidal turbines and rotor blades lined up for assembly onto the Cross Beam post launch.
Subsea manifold with the port and starboard umbilicals offered up ready to connect all the pneumatic, hydraulic, data and power cables.
