Whereas new submarine cable programs are being constructed to broaden international web capability, the upkeep of submarine cables has not seen the funding required to take care of these programs.
On this episode of the TeleGeography Explains the Web podcast, Mike Constable of Infra-Analytics and TeleGeography’s Alan Mauldin talk about their landmark report, “The Way forward for Submarine Cable Upkeep: Developments, Challenges, and Methods.”
Their work supplies context and insights for trade professionals, authorities policymakers, and different stakeholders to grasp additional the importance of this vital sector and its function in guaranteeing the safety and resilience of submarine digital infrastructure. (You possibly can obtain the report right here.)
Listed below are some key takeaways from the dialog.

The State of Submarine Cable Upkeep
Right now’s upkeep panorama is formed by a number of converging pressures. Many cables deployed in the course of the dot-com growth of the late Nineteen Nineties at the moment are nearing retirement. On the similar time, funding in new programs is accelerating, including tons of of hundreds of kilometers to the subsea community.
The upkeep ships which are important for repairing faults are an growing old fleet. Roughly 65% of cable upkeep vessels will attain the tip of their lifespan inside 15 years, however little funding has gone towards their inevitable substitute. Most are transformed secondhand ships from different industries, elevating issues about effectivity and reliability. In the meantime, governments are more and more classifying submarine cables as vital nationwide infrastructure, necessitating stronger resilience and sooner restore instances.
Modeling the Way forward for Submarine Cable Restore
To supply a data-driven basis for trade discussions, Mauldin and Constable constructed a analysis mannequin to forecast future upkeep wants. The mannequin began with estimates of what number of cables shall be lively over the following 15 years, factoring in each new builds and retirements. From there, it calculated
- Complete cable kilometers
- Historic regional fault charges
- Vessel availability to mission restore calls for via 2040.
Their conclusion: by 2040, at the least 15 new ships shall be required to interchange growing old vessels, plus a further 5 in Asia to fulfill rising restore demand. An funding of $3 billion is critical simply to take care of present service ranges, not enhance them.
The examine additionally integrated a broad trade survey, with over 60 stakeholders, together with upkeep suppliers, hyperscalers, carriers, and governments. Half of respondents mentioned they’d be keen to pay extra for upkeep companies if it meant sooner repairs, highlighting the worth positioned on resilience.
Subsea Cable Fault Hotspots, Dangers, and Suggestions
Whereas international subsea fault charges have been comparatively secure, the examine recognized particular areas of concern. Southeast Asia, and notably the South China Sea, accounts for practically half of world annual faults. That is largely attributable to intense fishing exercise, mixed with overlapping maritime jurisdictional claims that complicate allowing and delay repairs. Different hotspots embody the Purple Sea and chokepoints between Taiwan, China, and the Philippines, the place subsea landslides and geopolitical tensions enhance dangers.
In these areas, sooner allowing processes, higher collaboration between governments and trade, and diversified routing of recent cables might all assist enhance resilience.
This analysis additionally highlights a broader shift in trade dynamics. Conventional carriers are stepping again, whereas hyperscalers like Google and Meta at the moment are the first traders in new programs. This altering possession construction will form how upkeep is funded and prioritized going ahead.
The Way forward for the Business
The submarine cable upkeep trade has lengthy been in want of the info this report supplies. Now that Mike and Alan have accomplished the laborious work of amassing and analyzing this information, stakeholders can transfer ahead with methods and insurance policies to resolve these issues.
With growing old belongings, concentrated regional dangers, and rising authorities scrutiny, the cable trade faces a pivotal second. Addressing these challenges would require collaboration, funding, and maybe new financial fashions to make sure that the world’s digital lifelines stay resilient for many years to come back.
