My Lords, I too begin by thanking the noble Lord, Lord Harris of Haringey, for securing this debate. I also thank all noble Lords for the fascinating contributions that we have been privileged to hear in your Lordships’ House this evening. Since I arrived here a year ago, I have never had a day without learning something new and this evening is absolutely no exception. I will endeavour to cover the points raised, but if time does not permit me I will write to noble Lords on any outstanding issues.

As all noble Lords have pointed out, the SS “Richard Montgomery” is very different from most World War II wrecks in UK waters. It rests in shallow water near residentially populated areas and approximately 1,400 tonnes of explosive munitions remain on board. That figure is the net explosive weight, rather than the net cargo weight, which is what I believe the noble Lord, Lord Harris, was referring to. I think that, rather than the mystery disappearance of munitions, explains the discrepancy.

We understand that much of the explosive content still aboard is TNT, but we also understand that there is white phosphorus on the wreck in the form of signals and smoke bombs, which are in the deep tanks, and the surveys show no breaches. I will double-check this following the debate but my information is that we have no recorded examples of phosphorus escaping.

Several noble Lords, including the noble Lords, Lord Harris and Lord Addington, asked about the state of the munitions. Although we are not in a position to understand fully the condition of the munitions, we believe that the TNT is likely to be inert because the fuses have degraded over time. I am afraid we do not have an estimate of the cost of removing the munitions, as the noble Lord, Lord Rosser requested.

Has there been any historical study of this type of fuse and the rate at which it deteriorates? That is the only solid information that we could get. Has anything been done about that? Apparently it is a standard bomb so there must be other examples.

There are two answers to that question. Historically, a number of these bombs were shipped unfused, but the records are not available to know whether they were fused or not. In everything we have done, we have made the most cautious assumptions. The other modelling that has been done involved testing similar explosives to see what state they would be in, but that has not been done on the explosives on board the vessel.

The Government take their responsibility for the wreck extremely seriously. As part of our legal duty under Section 2 of the Protection of Wrecks Act 1973, we have designated a prohibited area around the wreck, and it is an offence to enter this area without the written permission of the Secretary of State. The last known unauthorised incursion into the area was by a paddle-boarder, to whom the noble Lord, Lord Harris, referred, in 2015.

If that was the most recent case—if it were, that would perhaps be reassuring—how quickly were the authorities able to get to the paddle-boarder and remove him?

I will have to write to the noble Lord in response to that.

He asked about the assessment made by the Royal Military College of Science in 1970. More recent studies have suggested different outcomes from the one outlined there, but a full assessment of a mass detonation is difficult because of the problem of understanding the condition of the munitions—a point to which I have already alluded. He also asked about the 1999 risk assessment. I have been advised that there is a hard copy of it in the Libraries of both Houses.

The noble Lord, Lord Rosser, asked about the basis for the Maritime and Coastguard Agency’s current assessment of risk. The hard evidence that supports this comes from the regular surveys that we carry out and the advice over many years that the cargo is likely to be stable if left undisturbed. I stress that we always take the most cautious approach to our assessments.

A further part of our ongoing work to mitigate the risk that the SS “Richard Montgomery” poses is ensuring that regular surveys are undertaken to understand the condition of the wreck and its surrounding environment. My noble friend Lord Patten stressed the importance of the use of risk-assessment data—I do not know whether it is big data but it is certainly data—in our work. The surveys are commissioned by the Maritime and Coastguard Agency and are undertaken by commercial offshore survey contractors.

The noble Lords, Lord Rosser and Lord Addington, asked about the environmental monitoring around the wreck. No specific environmental issue prompted the action; it was a pre-emptive move as part of our ongoing commitment to manage the wreck.

In response to a question from the noble Lord, Lord Rosser, the monitoring will also study what effect the wreck may or may not be having on its immediate environment—for example, through measurement of the water quality around the wreck. This monitoring is ongoing and will be completed later this year.

As my noble friend Lord Patten mentioned, on 3 June this year we published, on GOV.UK, the most recent surveys online for 2016 and 2017. This underlines our ongoing commitment to transparency in our monitoring of the wreck. As noble Lords have noted, these surveys confirm that the wreck of the SS “Richard Montgomery” remains stable but its gradual degradation continues. However, as the noble Lord, Lord Greenway, pointed out, technology is improving all the time, allowing us to understand the situation better.

The noble Baroness said that the report considers that the explosives pose no risk if the wreck is stable and nothing moves. Has anyone carried out an assessment of what would happen if something hit it? It is fine having the zones around it and 24-hour monitoring, but if a ship is going to hit it, there is nothing that anyone can do about that. Has there been an assessment of what would happen if a ship did hit it?

I am not aware of whether an assessment has been made but I will write to the noble Lord to confirm on that point. The noble Lord, Lord Greenway, mentioned the establishment of the expert advisory group to help us to consider how best to manage the wreck in future. This was formed in November 2017 and is made up of an independent chair, experts from the salvage industry and various government experts with knowledge of dealing with wrecks or experience of dealing with munitions of the type contained in the wreck.

An important function of the group is to provide a steer of potential options for long-term management of the wreck. The group is currently considering whether monitoring and regular surveying is still the correct course of action or whether a more proactive intervention should be considered. As the noble Lord, Lord Berkeley, suggested, interventions could include the removal of munitions or some form of containment of the wreck, as the noble Lord, Lord Addington, mentioned. I stress that the advice I have been given is that this is not as straightforward as the noble Lord perhaps suggested.

On the decision-making responsibility, any decision about a change of approach to the wreck would be made by Ministers. We appreciate that there are no risk-free options, as noble Lords have pointed out, which is why we are using the most qualified experts we can find.

The noble Lords, Lord Harris and Lord Addington, asked about contingency planning in the event of an incident. Responsibility lies with the Kent Resilience Forum, which includes all the first-response services. It is kept closely updated about the results of the survey and has wider plans for the safety of the area, of which any incident with the wreck obviously forms a key part.

The noble Lord, Lord Harris, asked about a tidal wave that might travel up the River Thames in the event of a detonation. We do not believe that would be the outcome. Rather, we believe there would be a sudden displacement and replacement of water, which would impact the immediate vicinity but would not form a travelling wave.

The noble Lord also asked about incidents and incursions. We have talked about the paddle-boarder and the Chinese fishing boat in 2002. We believe that the 2012 security operation was precautionary. I have no record of other incidents.

With regard to conversations with the US Government, the department is not sure why any offer of help was rejected. The issue has not been discussed recently and responsibility sits clearly with this Government.

To conclude, I again thank the noble Lord, Lord Harris, for bringing this debate on such an important issue and all those who have spoken. I hope that the measures I have outlined in my response provide some confidence to those who live near the wreck, and to your Lordships, that the issue is taken with the utmost seriousness by the Government. The SS “Richard Montgomery” remains the most surveyed and the most monitored wreck in the country.

House adjourned at 8.23 pm.
