Tusass Proactively Protects Critical Subsea Cables

The challenge

Subsea telecommunication cables constitute a critical part of national and transnational communication networks and infrastructures.

Despite regulation of traffic and activities in protection zones around cable infrastructures and clear markings on navigational charts, damages caused by vessels occur – e.g. inflicted by bottom trawling or anchors which pose substantial threats to the integrity and expected or residual life time of the cables. The economical and societal consequences can be significant for Tusass as well as the end users of their services.

The solution

Event detection algorithms developed by Gatehouse Maritime enable zone-specific detection of sea level events with probability of interference on the structural integrity of the subsea power and telecommunication cable infrastructures.

Vessels approaching and entering the protection zones are automatically notified and warned, by message on display or by SMS/email, in case they show evidence of contingency or potentially violating behaviour.  These timely warnings are a valuable tool for prevention of damages.

Furthermore Tusass is now able to easily identify and document perpetrators in relation to breakages on their subsea cables.

We can now identify and document perpetrators which is undeniable proof in insurance lawsuits. This has already resulted in compensations for millions.
