BJRE operated with 21 years experience in Marine Renewables. At the time, we were the Electrical Consultant and Contractors to the European Marine Energy Centre on Orkney, where we amassed a wide range of experience in terminating and testing submarine cables for both EMEC and the developers of wave and tidal devices who use the facilities that EMEC provide. Whilst onshore wind farm cable terminating and testing is relatively straight forward, work on subsea cables requires higher levels of expertise. We carried out a wide range of different types of termination and test works for the marine energy sector including:

  • Subsea cable stripping and preparation (double wire armoured cables, dry and flooded), Cable splicing and termination works (power core, auxiliary cores and fibre optics), Cable testing – DC, VLF, TDR, OTDR, etc. All from both onshore and offshore ends of the cables.
    • ​

    We worked very closely with the testing facility on electrical operations and maintenance, at both the wave site at Billia Croo near Stromness, and the tidal site at the Falls of Warness, off Eday. EMEC’s role is to give developers the opportunity to generate electricity at sea and feed that power into the National Grid – BJRE’s expertise was crucially important in making these high-voltage electrical connections work safely and successfully.

    ​BJRE developed a portfolio of new services tailored to the needs of the developers involved in wave and tidal energy generation.As the Electrical Consultant to EMEC, we regularly carried out design reviews for marine energy developments. Using ETAP software, we carried out all manner of design studies including:

  • Short Circuit Analysis, Load Flows, Transient Stability Analysis,Earth Grid design, Hot / Cold site determination, Cable Thermal Rating Studies


    • Subsea Cable

    We provided a range of subsea cable preparations and testing.
