Subhub Project Fully Funded for the Sea Trials

QED Naval has successfully completed the final round of funding to complete the sea trials of their Subhub tidal turbine foundation platform. The funds have been raised through the existing shareholding with 75% raised through Kelvin Capital and the remaining through Scottish Investment Bank (SIB).

The funds will be used for ballasting trials to demonstrate how quickly and easily Subhub can be installed and recovered in real sea conditions (in waves and tide). The trials will also demonstrate the significant increase in energy generated by mounting the turbines on the Subhub platform (up to a 40% increase in power output) thereby increasing capacity factors and making some sites commercially viable. QED will then assess the performance impact of Subhub on tidal turbines in accordance with the IEC standards.

QED Naval are now recruiting 4 new positions building its team to support the next stage of trials and the ongoing technical development of the Subhub leading to the companies first commercial deployments. See the Team/Join Us link for further information. In short, the company is looking for:

  • Electrical & Instrumentation Control Engineer
  • Naval Architect
  • Fluid Loading CFD Engineer
  • Structures Design Engineer

QED Naval have been collaborating with Queen’s University Belfast (QUB) and the Centre for Advanced Sustainable Energy (CASE), part of Invest Northern Ireland’s £10m centre for industry-led sustainable energy research. Specifically, this collaboration has been part of the Tidal Turbine Testing project (TTT), which is used to determine the impact of turbulence on the prediction of tidal turbine performance. In summary, flow  measurements have been recorded using ADCP systems to try and understand the behavior of the turbines in turbulent conditions. These measurements have then been used by QED Naval to predict the performance of a hypothetical turbine and then determine the impact of Subhub on the performance with impressive results.

Streamlines through the semi-duct of the Subhub and sliding mesh turbine.

As a result of this collaboration QED Naval have decided to test the Subhub in Strangford Lough at the QUB tidal test site, leased from the Crown Estate.

Also, as part of the ongoing support, QED Naval are sponsoring 2 industrial Ph.Ds, one on turbulence modelling and the other on remote sensing mapping of resources as part of their involvement with The Bryden Centre supported by the EU’s INTERREG VA Programme. There are still vacancies for these posts so please follow the link for contact details if this is of interest to you. These studentships are not exclusive to Northern Ireland or Ireland but also includes the University of the Highlands and Islands so it has broad appeal.
