About Us

C-Kore Systems Ltd

C-Kore Systems Ltd was founded to bring modern testing technology to the subsea industry.

We started our journey as part of Zetechtics, designers and manufacturers of the award winning Jupiter subsea control systems, before being launched as an independent company in 2012. The early years of C-Kore were spent on research and development, we started with our Cable Monitor tool and the low-voltage IR testing concept. This went through many prototypes and two generations of field-trials with customers, before further development to the commercial (third generation) design.

After gaining market trust in 2015, the following years saw widespread adoption of the C-Kore Cable Monitor as it benefits became apparent to our customers. The cost savings and measurement improvements have led it to become the de-facto choice for our customers’ subsea testing needs. As well as continually improving the technology, we have used our knowledge to develop new tools for the subsea industry, such as our Cable TDR and Pressure Monitor.

We have a team of dedicated designers and engineers who are passionate about making life easier for subsea engineers by bringing fast, modern and reliable testing techniques to the offshore industry.

What we say

“It’s been vital to keep C-Kore tools extremely simple to use while giving the rich set of features our customers need. You can change settings, run measurements and view results all very easily. I’ve always believed you can gauge a product’s quality from its appearance. A C-Kore tool is not just another tin can, it’s a beautifully engineered device.”
