C-Kore Systems successfully executed an electrical fault-finding campaign on a subsea field to test the subsea electrical control system and identify the precise location of insulation resistance faults. The ease of deployment from the ROV, equipment reliability, and the quick and accurate results provided by the C-Kore units allowed the operator to efficiently locate line faults and initiate repairs, ensuring the campaign was a great success.C-Kore Systems successfully executed an electrical fault-finding campaign on a subsea field offshore Australia. Both the C-Kore Cable Monitor units (IR) and Subsea TDR units were used to test the subsea electrical control system and identify the precise location of insulation resistance faults. The ease of deployment from the ROV, equipment reliability, and the quick andaccurate results provided by the C-Kore units allowed the operator to efficiently locate line faults and initiate repairs, ensuring the campaign was a great success.
