#underseacable — Public Fediverse posts

So, "they" want to build an undersea power connection from Canada to Europe. Communications links are technically complex but well-understood at this point. Long distance (4000 km) power transmission is a whole 'nother kettle of fish.

The technical summary is fascinating:
https://nato-l.com/documents/2607-JDN-NATO-L-Executive-Summary.pdf

2 GW transmission at 525 kV - or possibly 800 kV in another installation - is impressive. Sudden failures at that power level tend to resemble major bombing campaigns rather than electrical failures.

It will be interesting.

#China ship spotted lurking over #US-#Taiwan #underseacable
A new video shared by Newsweek shows Taiwan’s Coast Guard warning a 200-ft long Chinese-flagged research vessel to change course. Chinese ship was observed “lurking over [a] US-Taiwan undersea cable,” according to the source.
Maritime analysis platform Windward tracked 200ft China-flagged vessel "loitering at slow speed" directly over Pacific Light Cable Network in the Philippine Sea—an 8,000mi fiber-optic cable.

Somewhere in Bass Strait right now, a US government cable ship is maintaining Google's Internet.

#Taiwan activates backup communications for outlying island after #underseacable breaks
Bad weather has caused a shipwreck sitting on the seafloor to shift its location, severing the underwater link.
The crucial Taiwan undersea cable was severed by an old shipwreck — backup microwave communications activated to keep population connected
Although this incident was caused by natural forces and not an action by a third-party actor, it still highlights Taiwan’s vulnerability.

The UK and Norway foil a Russian submarine plot to survey undersea cables.

The UK and Norwegian militaries led an operation to deter Russian submarines suspected of “malign activity” in the north Atlantic, the British defence secretary said on Thursday.

Britain and Norway operate joint naval patrols aimed at protecting critical infrastructure in the North Atlantic.

#Underseacable cutting shenanigans lead #Finland to create a dedicated maritime surveillance center — Russian shadow fleet operations heighten concerns in the #BalticSea
According to Mikko Hirvi from the Finnish Border Guard, new measures include seabed sensors, AI-infused real-time analysis of maritime traffic, and improved exchange of vessel information with allies. These features will be subject to a gradual buildout, adding to the Border Guards' existing abilities.

A vessel coming from Russia dragged its anchor before a subsea cable was damaged.

The anchor of a vessel that damaged an undersea cable linking Helsinki and the Estonian capital Tallinn dragged along the seabed “at least several tens of kilometres” before it hit the line, Finnish police said Sunday.

On 31 December police detained the Fitburg, a 132-metre-long cargo ship en route from St. Petersburg.

First Ship Seized For #UnderseaCable Cutting Since #NATO's #BalticSentry Began
Finnish authorities have seized a Turkish-owned cargo vessel suspected of damaging an undersea telecommunications cable running from Helsinki to Tallinn, Estonia. This marks the first incident involving suspected sabotage of critical undersea infrastructure in the region since the creation of a NATO task force nearly a year ago to defend those cables, a NATO official told us. https://www.twz.com/news-features/first-ship-seized-for-undersea-cable-cutting-since-natos-baltic-sentry-began

"Finnish authorities have seized the cargo ship Fitburg off the coast of Porkkala in connection with damage to an undersea data cable owned by telecoms provider Elisa. The vessel, which departed from Saint Petersburg on 30 December, was intercepted in the Gulf of Finland after being identified as the suspected source of a disruption to the connection between Helsinki and Tallinn."

Amount is double 2022-2024 spend, and much as you'd expect, it's driven primarily by #bigtech (Meta Amazon Microsoft Google).

#Japan to subsidize #underseacable #vessels over 'very serious' #nationalsecurity concerns — will front up to half the cost for $300 million vessels bought by #NEC
NEC is one of the largest layers of undersea cables and biggest in #Asia, having already installed over 400,000 km globally. It currently competes with US-based SubCom, the French government-owned Alcatel Submarine Networks, and China’s HMN Tech. NEC does not own any cable-laying ships and instead leases them.

Undersea breaks on #SEAMEWE4 and #IMEWE systems disrupted #Microsoft’s Middle East transit over the weekend.
Those reroutes currently remain in effect, with Microsoft noting that they expect “higher latency on some traffic” as regional carriers continue to triage routes.

Sweden investigating new reports of Baltic Sea cable damage.

Sweden's coast guard has dispatched a vessel to waters east of Gotland. A number of telecommunications and power cables have been damaged in the Baltic Sea in recent months.
