Liberty Lines Commissions First High-Speed Ferry With mtu Hybrid System From Rolls-Royce
The title of this post, is the same as that of this press release from Rolls-Royce.
These two bullet points act as sub-headings.
- “Vittorio Morace” the world’s first hybrid high-speed ferry to IMO HSC standard with a length of almost 40 metres is fast at sea and emission-free in harbour
- A further 8 Liberty Lines ferries with mtu hybrid systems will enter into service in Italy, Slovenia and Croatia
This picture shows the first of the fleet.
This is the first paragraph.
On 27 June 2024, the Italian shipping company Liberty Lines ceremonially launched the world’s first hybrid fast ferry of this category and size in Trapani, Sicily, powered by an mtu hybrid propulsion system from Rolls-Royce. The 39.5 meter long ship has a capacity of 251 passengers, reaches a speed of over 30 knots and will significantly reduce the impact of ship operations on the environment. The “Vittorio Morace”, built by the Spanish shipyard Astilleros Armon and designed by Incat Crowther, is the world’s first IMO HSC (High-Speed Craft) hybrid fast ferry of this size and has been classified as a “Green Plus” ship by the Italian classification society RINA.
This ferry can truly be considered to be a Ship-of-the-World, with a design from an Australian-headquartered International company and German engines, that has been built in Spain.
This paragraph describes the power-train.
The battery-electric part of the drive is used for locally emission-free driving in the harbour area and as a booster. CO2 emissions are reduced by the particularly efficient mtu Series 4000 diesel engines which can also run on the renewable diesel (HVO, hydrotreated vegetable oil). Its use can lower the CO2 footprint by up to 90 per cent. Furthermore, the comparatively low overall weight of both the engines and the hybrid drive system contributes to high vessel propulsion efficiency, thereby reducing fuel consumption and emissions.
Over the last thirty years, I’ve been to several of the places served by Liberty Lines, so some excellent journeys, will be made faster, quieter and better.
Appropriate Nutrient Supplementation In Coeliac Disease
The title of this post, is the same as that of this article on PubMed.
I choose this article, as the abstract gave a good list of related problems to coeliac disease.
This is the abstract.
Reduced levels of iron, folate, vitamin B12, vitamin D, zinc, and magnesium are common in untreated celiac disease (CD) patients probably due to loss of brush border proteins and enzymes needed for the absorption of these nutrients. In the majority of patients, removal of gluten from the diet leads to histological recovery and normalization of iron, vitamin, and mineral levels. Iron deficiency anemia is the most common extra-intestinal sign of CD and usually resolves with adherence to a gluten-free diet. However, deficiencies of both folate and vitamin B12 may persist in some patients on a gluten-free diet, thus requiring vitamin supplementation to improve subjective health status. Similarly, exclusion of gluten from the diet does not always normalize bone mineral density; in these cases, supplementation of vitamin D and calcium is recommended. Resolution of mucosal inflammation may not be sufficient to abrogate magnesium deficiency. Since gluten-free cereal products have a lower magnesium content as compared with gluten-containing counterparts, a magnesium-enriched diet should be encouraged in CD patients. In this article we discuss the frequency and clinical relevance of nutrient deficiency in CD and whether and when nutrient supplementation is needed.
I am coeliac and was diagnosed at fifty, by by a mixture of the suspicions of an elderly locum, the very modern genetic test and the classic endoscopic test , in the last few years of the twentieth century.
I have to admit, that being diagnosed was a bit of a surprise.
Are Bodies Cleverer Than We Think?
Because, I had a serious stroke thirteen years ago, I am on Warfarin for life to thin my blood, so that I don’t have another stroke.
INR is short for International Normalized Ratio, which diverts on Wikipedia to the Wikipedia entry for Prothrombin Time, where these is the first two paragraphs.
The prothrombin time (PT) – along with its derived measures of prothrombin ratio (PR) and international normalized ratio (INR) – is an assay for evaluating the extrinsic pathway and common pathway of coagulation. This blood test is also called protime INR and PT/INR. They are used to determine the clotting tendency of blood, in such things as the measure of warfarin dosage, liver damage, and vitamin K status. PT measures the following coagulation factors: I (fibrinogen), II (prothrombin), V (proaccelerin), VII (proconvertin), and X (Stuart–Prower factor).
PT is often used in conjunction with the activated partial thromboplastin time (aPTT) which measures the intrinsic pathway and common pathway of coagulation.
That is very technical and complicated, but what does it mean practically?
Those on Warfarin to thin their blood are generally supposed to keep their INR between 2 and 3.
I test the INR myself with a Coaguchek meter from Roche and have done so for nearly ten years.
Every, so often, I discuss the level of Warfarin with my GP and we adjust the level accordingly.
Typically, NHS patients on Warfarin have their INR checked every few weeks.
But as I am a Graduate Control Engineer, who has written control strategies for chemical plants, I feel this checking every few weeks, is not enough.
At times, I have checked at a higher frequency.
Four times, I have had minor operations.With the first operation, I agreed with the surgeon, that I would lower my INR to 2.1 for the operation and raise it back to 2.5 after the operation.
It all went well and I repeated the exercise for the three other minor operations.
I have checked daily since about the beginning of April, before which, I generally tested on Mondays and Thursdays.
There were two reasons for the change of frequency.
- Regular storms seemed to roll in and for some reason, they tended to lower my INR.
- I also wrote Do Thunderstorms Cause Strokes?, after reading a paper from the United States about the relationship between thunderstorms and strokes.
So I took the prudent decision to test my INR daily.
Then on the 30th May, disaster struck.
My Coaguchek meter found out it had the wrong firmware and Roche implored me to change it.
But I am not a hardware person, so I was left unable to check my INR.
Luckily, I remembered a story from the 1960s about one of ICI’s chemical plants.
This plant was one of the first fully-digitally controlled plants controlled by an IBM 1800 computer.
It also ran 24 hours a day, seven days week.
So in the middle of the night, the plant operators got out all the computer printouts, which showed how the computer had set all the valves and controllers.
One-by-one they reset all the controls on the plant to the settings that the computer had used for the last few days.
Using, this computer-assisted mode the plant was kept running, until engineers could fix the computer.
On the 30th May, my INR was a little bit high at 2.9 and I was using a dosage of Warfarin of 4 mg. one day and 3.5 mg. the next.
The strange dosage was one, that I know from experiment over time produces an INR of 2.5.
My actual average Warfarin dose was 3.73 over the last thirty days and my INR, as measured most days was 2.6 over the same period.
So, I did what the engineers did on the chemical plant, kept calm and carried on.
Yesterday my son fixed the Coaguchek meter and I was able to take my first reading for 17 days. It was 2.7 and only 0.1 higher than the 30-day average on the 30th May.
I had successfully jumped the gap in the readings.
Conclusion
Most systems have an equilibrium. Make sure you know it.
Wood To Optimise Hydrogen Storage For Centrica’s Rough Field
The title of this post, is the same as that of this press release from Wood plc.
These are the first three paragraphs.
Wood, a global leader in consulting and engineering, has been awarded a contract by Centrica Energy Storage (CES) for the redevelopment of the UK’s Rough field in readiness for future hydrogen storage.
The Rough reservoir, located in the Southern North Sea, has been used to store natural gas safely for over thirty years and has the potential to provide over half of the UK’s hydrogen storage requirements.
The front-end engineering design (FEED) contract, awarded to Wood, entails new pipelines, a new unmanned installation, as well as onshore injection facilities at the Easington Gas Terminal, is the first step in making the field hydrogen ready.
Offshore Magazine has this article about the deal, which is entitled Wood Assessing Hydrogen Storage Needs For North Sea Rough Reservoir.
This is a paragraph from the Offshore Magazine article.
Centrica aims to position the Rough Field as the world’s largest long-duration hydrogen storage facility, although FID on the redevelopment project would depend on government support.
It would be a very important project.
Why would Centrica be planning for this massive increase in hydrogen storage?
There could only be one reason.
There is going to be a massive increase in hydrogen production and use.
In Where’s The Plan, Rishi?, I laid out what I believe will happen in the next few years.
- In RWE Goes For An Additional 10 GW Of Offshore Wind In UK Waters In 2030, I detailed how RWE intended to add an extra 10 GW of offshore wind to the seas around the UK.
- As our current offshore wind capacity is around 15 GW, so another 10 GW would surely be very welcome.
- The Germans will develop H2ercules, which is their massive project to create a hydrogen network to bring hydrogen to Southern Germany.
- A hydrogen hub at Wilhelmshaven is being built by Uniper to feed H2ercules with green hydrogen from around the world.
But would it not be better, if instead of feeding H2ercules with hydrogen from around the world, some came from the UK, a few hundred miles across the North Sea?
- RWE are developing the 3 GW Dogger Bank South wind farm, which is not in the best place for a cable to the UK. So could this wind farm have an offshore electrolyser and send the hydrogen to Wilhelmshaven, by pipeline or coastal tanker?
- RWE are also developing the 4.2 GW Norfolk cluster of wind farms to the North-East of Great Yarmouth. It might be better, if the output of these wind farms took a hydrogen route to Wilhelmshaven.
- I also believe that a third offshore electrolyser might be situated North of the Wash to bring more hydrogen to Germany.
- Hydrogen could also be sent from the Rough facility to Wilhelmshaven.
The coastal tanker route gives flexibility, so green hydrogen could be sent as required to the UK mainland.
Rishi Sunak’s Manifesto Speech – June 11
I also reported on Rishi Sunak’s Manifesto Speech, which he made on June 11th. This is an extract
This document on the Policy Mogul web site is entitled Rishi Sunak – Conservative Party Manifesto Speech – Jun 11.
These are three paragraphs from the speech.
We don’t just need military and border security. As Putin’s invasion of Ukraine has shown, we need energy security too. It is only by having reliable, home-grown sources of energy that we can deny dictators the ability to send our bills soaring. So, in our approach to energy policy we will put security and your family finances ahead of unaffordable eco zealotry.
Unlike Labour we don’t believe that we will achieve that energy security via a state-controlled energy company that doesn’t in fact produce any energy. That will only increase costs, and as Penny said on Friday there’s only one thing that GB in Starmer and Miliband’s GB Energy stands for, and that’s giant bills.
Our clear plan is to achieve energy security through new gas-powered stations, trebling our offshore wind capacity and by having new fleets of small modular reactors. These will make the UK a net exporter of electricity, giving us greater energy independence and security from the aggressive actions of dictators . Now let me just reiterate that, with our plan, we will produce enough electricity to both meet our domestic needs and export to our neighbours. Look at that. A clear, Conservative plan not only generating security, but also prosperity for our country.
It is now nineteen days since Rishi made that speech and I can’t remember any reports about an energy security policy, which he outlined in the last paragraph of my extract from his speech.
He particularly mentioned.
- New gas-powered stations
- Trebling our offshore wind capacity
- Having new fleets of small modular reactors.
He also said we would have sufficient electricity to export to our neighbours. As I said earlier some of this energy will be in the form of hydrogen, which has been created by offshore electrolysers.
If we are exporting electricity and hydrogen to Europe, this is likely to have three effects.
- An improvement in Europe’s energy security.
- H2ercules will improve and decarbonise German industry, using UK hydrogen.
- The finances of UK plc will improve.
It looks like there will be winners all round.
Conclusion
Centrica’s plan for a massive hydrogen store at Rough, close to SSE’s existing gas storage in the salt caverns at Aldbrough, would appear to make sense, if the UK’s excess of offshore wind is converted into green hydrogen, which is then stored and distributed as needed.
