Wirescan has today received a PO from a Scandinavian cable manufacturer to perform LIRA measurements during the installation steps of a high voltage power cable to be installed in the Norwegian North Sea.
Wirescan will travel to the manufacturer site and perform LIRA measurements before and after load-out to the installation vessel. The cable will be supplied in two separate lengths, later to be spliced together. LIRA measurements will therefore be performed during two campaigns at the manufacturer’s site.
Wirescan will then travel to the Norwegian installation site several times to perform LIRA tests after pull-in to shore, after jointing of the two lengths, after rock-dumping and before/after high voltage tests. All the Wirescan measurements will be compared to secure the integrity of the cable during the transportation and installation campaign.
This LIRA campaign is initiated by the end client, and will provide valuable proof for the client that the integrity of this critical power-from-shore cable is maintained during the whole process. The final test after installation will be used as a reference of the cable condition for future cable condition monitoring and potential cable fault location.
