Client Advice
Technology agnostic advice on assessing cable health and protecting cables.
Cable Health
Offshore Wind & Interconnects
Early planning is crucial for cable health in offshore wind projects, beginning years before installation. Whilst Construction and Operations Plans (COP) / O&M Plans are required, choosing the right monitoring approach can be challenging.
We help developers navigate complex decisions about sensing technologies and monitoring systems, transforming uncertainty into confident infrastructure choices that support reliable, sustainable power delivery and empower your Operations and Maintenance teams.
Information on what to do is often clouded and opaque with vendors promising everything and developers left asking questions:
- But what technologies to use?
- What does fibre sensing do for me?
Sensing Advice for O&M managers & Cable Engineers
As hardware agnostic, experts in fibre sensing we publish a guide to help developers and asset owners cut through the hyperbole of what technologies will help them with cable help.
If you’d like an instant download copy of the recommendations document, head to the bottom of the page. You can download the first few pages here.
Once O&M statements are made to achieve lease, the developer then needs to consider what the ROI will be on technologies. To help with this we can also provide a Value Calculator to help understand savings both operationally and in prevented cost of failure.
- Explore cost minimisation for array cables
- Understand O&M savings
- Understand separate footprint for export cables
The result? Risk is lowered and needless expenditure is eliminated.
If you’d like to understand more of the savings that cable health monitoring can provide, contact us for a bespoke version of our VP calculator – we will populate it with the details of your windfarm but you can change all the assumptions and decide for yourself whether cable monitoring is worthwhile.
Critical Infrastructure
Securing Our Renewable Future: Offshore Wind & Power
The security of subsea power cables is in the news more and more. Most nations on the planet are moving critical electricity generation offshore as part of the move to electrification and the search for a cost-effective net zero.
Ocean renewables are not protected by fences and the power cables returning to land (like our data cables) become delicate umbilicals, keeping the lights on.
As stewards of this clean energy revolution, safeguarding these essential connections that power our sustainable future is a growing priority for offshore wind farm operations.
Protecting Undersea Infrastructure
Our advanced monitoring system safeguards critical submarine cables from threats both deliberate and accidental. While isolated incidents can damage individual cables, coordinated attacks pose an even greater risk to global connectivity and commerce.
- Monitor the vicinity of cables for suspect ships with AIS turned off – understand whether your cables are being surveilled
- Understand whether such action extends to below the waterline – have cables been interfered with?
- Carry out forensics on suspect activity
Here the Indeximate approach affords two key benefits:
Don’t wait for a crisis. Secure your undersea assets with real-time monitoring and threat detection that keeps your network safe and reliable.
Insight for O&M
Offshore Wind & Interconnects – Operations
The sensors we use are sophisticated and ridiculously sensitive virtual strain gauges. This gives us all the vibrational and acoustic data necessary to understand the state of the cable.
It also gives us more.
Did you know that the sensitivity is such that we can measure passing waves on the surface with a sensitivity of ~0.1mm of wave height? Or detect and classify ships in the vicinity of the cable with wake patterns extending 10’s of km? We also feel the vibration of monopiles hundreds of metres away from the cable and can isolate modes of vibration and profile them against prevailing wind / wave direction? Whalesong is visible in the sensing record!
But, here's the best part...
All of these can be delivered as a low cost Sensing as a Service™ – purely a cloud subscription or analysis activity with no hardware. With all our data in the cloud we can turn on further processing. With our extensive history we can conduct extensive bespoke analysis or meta analysis.
Leading Industry Change
Health Monitoring for Insurers
We’re pioneering standardised approaches to submarine cable health assessment in an underserved industry.
While current standards from CIGRE and DNV offer minimal guidance, we’ve developed comprehensive recommendations to fill this critical gap.
Our industry-leading “Cable Health Assessment Requirements” document provides a standardised framework for the industry, published under an open license to encourage widespread adoption and improvement.
We're proud that the Global Undersea Hub has embraced this initiative, forming a working group to advance these standards further.
Download our requirements document below to join us in shaping the future of cable health assessment. You can download an extract here.
Cable Health Assessment Requirements
It’s our hope that an independent body will pick this up to offer direct advice to insurers – to achieve this we published with a creative commons licence to enable others to take, adopt and augment.
In support of the publication we also issued a couple of blog articles covering some of the issues with insurance, regulation and cable health as well as our suggestions for improving the situation.

Here we provided a vendor and technology agnostic overview of approaches to fibre optic sensing, outlining where they can be used and why, what the limitations are and once you have the raw sensing hardware what can be done with the data. Indeximate exists as a data science firm and without the correct hardware in place there is no data. Our motiviation is to pass on our long experience as leaders in fibre optic sensing to encourage uptake and therefore increase the ability in the future of Indeximate to supply more customers with cable health sensing measurements.
