Subsea Network Repaired in the North Sea

Faulty elements in the subsea network within the Greater Guillemot Area field were diagnosed and replaced within 24 hours of the start of a recent fault-finding campaign, subsea testing tools manufacturer C-Kore Systems said.

The GGA area in the UK North Sea is operated by Dana Petroleum with partner Tailwind.

C-Kore’s compact Cable Monitor Units are used on fault-finding operations and installation campaigns to test the health of electrical lines by measuring the insulation resistance and electrical continuity. With their Subsea TDR units, faults can be localized with an accuracy of 10cm in the cables. C-Kore has recently brought out their new Sensor Monitor that can read subsea wellhead gauges and other subsea sensors directly without a control module or datalink pre-sent.

Greg Smith, General Manager of C-Kore Systems, said, “We have invested considerable time designing our units to be versatile while remaining very easy to operate. Before work even begins, we work closely with our customers to ensure the tools and testing methodology are optimized for their work scope, with the aim of ensuring testing is as efficient and effective as possible.”
