Subsea Cables & Internet Infrastructure

Nordunet's cost estimates are way off base. It is not a 200 million Euro project, but a half billion Euro project. It would require a special cable ship designed for Arctic climates together with two icebreakers to be on the safe side. The proposed paths are as long as many non-Arctic cables whose construction costs were in the $200 million to $300 million range. But those projects did not require specially designed cable ships nor icebreakers for deployment or for the necessary geophysical survey undertaken before construction. The cable would probably be double armoured and the design phase costs alone probably twice the norm.  So it is a given that upfront costs will be extraordinarily high. And here is the dagger in the heart: ice scouring. Floating glaciers scrape the bottom of the sea floor in the Arctic coastal areas. One or two meter burial won't be enough for the Northwest passage route raising the cost. But going deeper for burial may require special equipment or not...

The EU recently gave 6 million Euros to the Northern European Polar Connect Initiative which aims to build a subsea cable connecting Japan to Europe via the Far North. See the map below for routing. NorduNet is a network linking universities and research organizations in the five Nordic countries of Denmark, Finland, Iceland, Sweden, and Norway. It is taking the lead on this project which is looking at two alternatives routes to reach Asia. One route would be via the North Pole and the other via the Northwest Passage. This would give Europe access to Asia without traversing the US or Canada and hence offer better privacy and more secure communication as well much lower latency. Because the proposed paths are highly diverse to the usual suspects of Atlantic cables landing in Canada or the US, they might be attractive for resiliency purposes. One can imagine carriers splitting their traffic between the Polar routes and the more traditional cross-US routes for Pacific/European traffic. C...
