The Derbyshire-based company secured a £7 million contract to design and build a unique engine test facility for the propulsion units for the Royal Navy’s six Type 45 destroyers. The 700m2 marine gas turbine test facility located in Bristol will be used for analysis and maintenance on the ships’ Rolls-Royce WR21 propulsion units and called on Quartzelec’s Rugby business for their assistance and expertise.

  • Supply of step-up power transformer (25 MVA, 4.16:11kV), MV switchgear and transfer panel
  • Installation of power transformer, MV switchgear and transfer panel, MV, LV and control cabling (by Quartzelec’s Wrexham business)
  • Commissioning of facility

The supply and installation phase of the project was successfully completed at the end of June, with pre-commissioning checks passed in advance of final commissioning August 2014.
