Briggs Marine – Burbo Bank OWF Export Cable – April 2019 

Correll Services was contacted and mobilised at very short notice to fault find on a subsea export cable.  Utilising four HV/FO testing technicians working from each end of the cable, we successfully located the fault 20-25 metres outside the onshore substation.  We completed the fault–finding process using the following equipment: 

• Bridge tester (HVB10) 
• Surge Tester (Thumper) 
• Optical Time Domain Reflectometry (OTDR)
