Why submarine cable monitoring matters to insurers.
As the need for renewable energy sources increases, so do damage claims of offshore wind farms. Facing the brunt such claims, insurance companies are turning to submarine cable monitoring. Over 80% of insurance claims were due to cable damage.

Many factors expose offshore power cables to damage and outages. The seabed is a dynamic environment and the ocean is home to numerous unexpected events such as anchoring, fishing, cable overheating, boat traffic etc.
In  alone, over 80% of insurance claims were due to cable damage. As wind farms are constructed in ever deeper waters around the globe, this number is expected to rise.
That is why insurers are increasingly interested in continuous submarine cable monitoring. Continuous monitoring allows O&M teams to observe evolutions and intervene before disaster strikes. With appropriate procedures in place, wind farm owners can reassure insurers that cable failures are less likely to take place, or that repairs can at least be planned. In turn, such reassurance will allow insurers to potentially lower their premiums.
The traditional approach for inspecting the health of a submarine cable.
Traditionally, these cables are inspected once a year by a survey vessel and often an unmanned vehicle. Surveys are expensive and only provide a single snapshot of the situation. If a cable gets exposed by a storm at sea, this will only be picked up at the next survey date, up to one year after the fact.
By continuously measuring temperature inside the submarine cable using the embedded fiber optic cable as a proxy, it is possible calculate the cable’s depth of burial up to 26 times a year, without the risk, cost and planning involved in sending a survey crew.

Poster Award at WindEurope Copenhagen for RTTR monitoring
Our R&D lead Manly Callewaert won the conference poster award at the WindEurope event. In collaboration with Elia, we succeeded in challenging the industry standard and improving the time accuracy on how to calculate the core conductor temperature within subsea cables for the offshore wind industry.
From raw data dump to actionable insights
Our goal at Marlinks is to turn data into actionable insights. In a nutshell, this means as a starting point we verify and enhance the quality of the raw data and afterwards we process the data to provide actionable insights to the client. Today we talk with our IT engineer Sander Van De Moortel, who’s working daily on developing and improving our software.
Meet Andy Readyhough, Brand Ambassador for the UK
Andy knows the offshore wind submarine power cable transmission market inside out, having seen first hand how the industry moved from oil & gas to renewable energies and combined with the telecom submarine cable industry has defined the current offshore wind cable industry standards. It was long overdue that we needed to share with our network a droplet of his insights.
