Listen to what your cables are telling you

Today, cable failure is largely unpredictable.

Preventative maintenance is limited to direct inspection every few years.

Wouldn’t it be better to be able to know the condition of cables and the environment they sit in? 

Know how much life is left – when there is time to react.

Optimise your direct inspection and reduce the environmental impact of expensive boats mindlessly patrolling the cable routes.

We prevent the failure of subsea cables.

Our Background & Purpose

Cables fail strand by strand

We understand cables. We start from first principles of investigating the nature of failure.

We understand fibre optic sensing.  With over 40 years of expertise we know the topic inside and out.  High fidelity Fibre Optic Sensing has the answers to understanding cable condition buried in the sensing record – but they are hard to extract.

Once a strand fails strain appears on the surface

Imagine putting a microphone in a busy office and trying to pick up a rarely occurring fault in the mains hum.   Fibre Optic sensing can do the same – but it’s hard. 

Volumes of data are crushing and the answers you seek only become apparent when you monitor for hours and days. The volume of data prevents conventional approaches.

Indeximate tackle both problems head on…

the conventional sensing industry has yet to provide a solution


Our output

Our Patented Electro Mechanical Weakness Indicator

We monitor your cable and profile it for weakness, our patented mechanical weakness metric produces a metre by metre measure of armour degradation & FO tube degradation, informing you on weak conditions.

But that’s not all or enough – we also profile the cable and the environment for abrasion, fatigue, vibration and exposure allowing you to pull together a complete story.

We deliver this in the Scattersphere which partners your existing fibre optic sensing hardware with our unique compression approach (Indeximation) to push the data to our cloud portal for total risk intelligence. We are hardware agnostic, we work with all suppliers, we don’t get involved in supply chain purchasing.

If you are yet to commit to buying permanent monitoring equipment we also offer turnkey health check reports where we manage all steps in the process form the short to medium term rental of interrogator equipment to setting up our systems and reporting on the health of your assets – both as a technical report and as a certificate of health for your insurers.


The Benefits

  • Cable lifetimes are extended
  • Inspection is targeted, cheaper and more efficient
  • Preventative maintenance can be planned with foreknowledge
  • Failure can be pre-empted
  • Corrective maintenance costs are reduced or eliminated
  • Insurance profiles are optimised

The result ? RISK IS LOWERED and needless expenditure is eliminated

An improved ownership experience

Why Indeximate?

How are we different?

We are hardware agnostic – we aren’t promoting expensive systems where you are unsure of the long term benefit

We are solely focussed on preventing failure of seabed cables. We aren’t distracted by other problems


We listen to what your cables are telling you. Most DFOS solutions just alarm on occurring failure. We view that as too late. We tell you far in advance of degrading condition with time to act.

We take a long term view and profile data for months and years – we are motivated by long term conditions.
