The TAT-14 telecommunications cable, which consists of two 19-year-old cables, is being decommissioned. This operation, carried out by Subsea Environmental Services, involves the recovery and recycling of the cable and bases, from land to deep water segments in the North Atlantic.
The first phase started in mid-April and will be completed by the end of 2021. It only concerns the onshore part, with the recovery of the coastal ends in Denmark and the Netherlands, but this work is not necessarily the easiest...
More than a year of planning has been required to consider the interests of multiple stakeholders in licensing, borders and jurisdictions, constructed buildings, crossings, and considerations of proximity to third party assets in various countries.
While the experiment is not new, it is being closely followed by the entire submarine cable community. It should allow for the identification of risks, analysis and implementation of necessary mitigations, while maintaining operations within a tight project schedule. Careful consideration of the project's impact on waste, environmental factors and opportunities to reuse portions are also examined.
Connecting Northern Europe directly to North America, TAT-14 has been replaced by the new Havfrue / AEC-2 cable since last month. This cable connects Denmark and Norway to the US, with a future extension planned for Ireland.
