UK-based C-Kore Systems has completed a successful campaign offshore Nigeria with VAYCO Oil tools and local Nigerian partner Cranium Engineering.

The operation for a major oil operator in over 1,000m water depth allowed rapid testing of umbilicals and electrical flying leads (EFLs) for regulatory compliance and immediate rectification of subsea faults, saving significant man hours and vessel time.

Being automated, the C-Kore units also reduce the number of personnel needed offshore.

C-Kore’s subsea testing units are used to verify the health of subsea electrical systems on both asset integrity and installation operations. The cable monitor unit tests the electrical line’s insulation resistance and continuity while the Subsea TDR unit locates faults with a precision of approximately 20 cm.

The new sensor monitor unit reads subsea sensors without needing a subsea control module.

Sola Adekunle, CEO of Cranium Engineering, said, “Our customer was pleased with how the C-Kore units operated, and the excellent service provided. We were able to get data that would have been impossible using traditional methods, improving asset integrity whilse saving the customer money on both man hours and on vessel time.

“The additional safety and operational benefits of having a simple, automated system where no extra offshore personnel is required was valuable in sustaining operations during the current COVID-19 pandemic.”

Greg Smith, general manager of C-Kore Systems, commented, “We are very happy to work again with VAYCO and Cranium Engineering. Our technology has proven to save time and money for our customers and our ‘Keep-it-Simple’ design philosophy allows easy and reliable testing without the need for specialist offshore personnel.”
