The exact location of the failure has been detected in the meantime with assistance from a ship carrying a Remote Operating Vehicle on board. Equipped with specialist detection equipment, this submarine vessel was able to determine the location of the cable failure to a high degree of accuracy. Repair work was started in parallel to this investigation.

TenneT has an adequate supply of reserve cables, thus reducing the amount of time needed for repairs. However, the company emphasizes, the repair process is very complex and requires specialist repair work. For example, a specialised cable-laying vessel and favourable weather conditions at sea are required in order for repairs to be carried out.  The overall repair time can be estimated as soon as more details are known.

NorNed is a joint venture between Statnett and TenneT, the electricity transmission operator of the Netherlands. TenneT and Statnett use the 580 km long cable to transmit electricity from Norway to the Netherlands and vice versa. The cable link went into service in May 2008.
