Undersea Cables

Lord Harris of Haringey Excerpts

Tuesday 3rd December 2024 Lords Chamber

Asked by

[Lord Harris of Haringey]

To ask His Majesty’s Government what assessment they have made of the recent severing of two fibre optic cables in the Baltic Sea and of the arrangements in place to protect undersea cables serving the United Kingdom.

[Lord Harris of Haringey (Lab)]

My Lords, I refer to my interest as chair of the National Preparedness Commission and beg leave to ask the Question standing in my name on the Order Paper.

[The Minister of State, Department for Science, Innovation and Technology (Lord Vallance of Balham) (Lab)]

We are working closely with international partners following the breakage of two subsea telecommunications cables in the Baltic Sea a fortnight ago. It is important that we let those investigations run their course. Subsea cables are critical to UK telecommunications digital infrastructure, and we are committed to maintaining and enhancing the security and resilience of that infra- structure. We will continue to co-ordinate with security partners, the subsea cables industry and international bodies on this issue.

[Lord Harris of Haringey (Lab)]

My Lords, I am grateful to the Minister for that reply and the recognition of the criticality to the UK of these subsea connections. What consideration are the Government giving to protection and making sure that we can recover quickly in circumstances in which those cables are disrupted or severed? I understand that in Australia, for example, the equivalent of Ofcom requires a licence from those making those connections, and that licence must specify what arrangements are in place for the immediate repair of any severed cable. Are we considering such measures or any others?

[Lord Vallance of Balham (Lab)]

I thank my noble friend for that question. There are 64 cable systems that leave the UK, with 116 cables. About 200 cables break every year around the world, and 10 to 20 of those are in the UK. There is a system of payment from the companies for a ship which gives 24-hour, seven-days-a-week coverage for repairs, as well as systems, of course, to get other commercial repairs done at a slower pace. We work closely with others around the world, including the Australians, and are aware of that model. There are rather specific circumstances which mean that, at the moment, that does not work here, but the ability to get ships rapidly to broken cables is important and that is facilitated by the planning arrangements in place.

Satellites: Adverse Effects on Astronomy

Lord Harris of Haringey Excerpts

Wednesday 20th November 2024 Lords Chamber

[Lord Vallance of Balham (Lab)]

My Lords, the question about the number of things circulating in space and the implications of that is very important indeed. The number of satellites projected to be launched by 2030 could be as high as 400,000, with estimates ranging from 50,000 to 400,000. This is a very big issue. The amount of space debris is increasing as well, which also contributes to the problem. The UK promotes the sustainable use of space and there is a range of initiatives, from regulation and standards to research, space observation and monitoring capabilities, as well as technologies for active debris removal and in-orbit servicing to try to make things last longer, all of which we will continue, along with the notion of satellite refuelling. This is a growing problem and one that we have raised with the United Nations body and will continue to do so.

[Lord Harris of Haringey (Lab)]

My Lords, I refer to my interests in the register as chair of the National Preparedness Commission. As an economy, we are increasingly reliant on positioning, navigation and timing signals from satellites in space. The Minister participated in the event organised by the Royal Institute of Navigation this morning, which I also spoke at. Could he share with us the Government’s plans around the vulnerability that our national economy and all our businesses will face if there is disruption to PNT signals, either because of space junk or solar activity, or malign activity by another nation? How well prepared are we to deal with those issues?

[Lord Vallance of Balham (Lab)]

This is a critical question. The Royal Institute of Navigation has recently—in fact, today—launched a paper on how to prepare for this. It is something that all critical national infrastructure will be urged to look at, to have a plan for what would happen in the event of GPS failure. There is a longer-term question about the alternatives to space-based navigation and there is active work going on in the UK on terrestrial approaches, including the use of quantum systems to try to get a robust secondary approach to PNT.
