Anything moving fast takes a lot more energy to cover the distance, (Drag::V^2) anything lifted off the ground by wings or thrust is inefficient, so resupply of our island (called BIHI, pron. Bee-Hee - Beyond Infinity Horizon Island) with Hydrogen or an H-N compound should be by ship.

OR, there is a mirror in space, renewable energy is beamed from shore and used to electrolyse seawater to make the Hydrogen, Ammonia, Hydrazene...

Sig, may I suggest limiting discussion of SpaceX ideas like the above to the SpaceX thread, at least until they become actual solutions and not just ideas or promises.

Discussion of ideas is what this forum is about. 

In truth, I was expecting someone to reply that 1 million cubic liters of hydrogen is not enough to supply even one ocean-going ship.
At 700 bar it gets smaller. One wonders whether the shipping industry is under enough pressure to do a Tesla on fuel storage and propulsion systems#, because elsewhere....

The US Office of Energy Efficiency and Renewable Energy has been working on H2 as fuel for yonks. But it has been focused on systems for ordinary autos. But the data is useful even though old.  From https://www.energy.gov/eere/fuelcells/physical-hydrogen-storage

Quote
Physical storage is the most mature hydrogen storage technology. The current near-term technology for onboard automotive physical hydrogen storage is 350 and 700 bar (5,000 and 10,000 psi) nominal working-pressure compressed gas vessels—that is, "tanks."


While low-pressure liquid hydrogen, near the normal boiling point of 20 K, is routinely used for bulk hydrogen storage and transport, there is currently little activity in developing it for onboard automotive use. While compressed hydrogen typically is stored at near-ambient temperatures, "cold" (sub-ambient but greater than 150 K) and "cryogenic" (150 K and below) compressed hydrogen storage are being investigated due to the higher hydrogen densities that can be achieved at reduced temperatures.

TECHNICAL TARGETS AND STATUS
The cost of current compressed gas systems for automotive applications is dominated by the carbon fiber composite with a significant impact from balance of plant (BOP) components. Current physical storage research and development efforts focus on reducing the cost of the fiber reinforced composite portion of the pressure vessel to help meet DOE targets. These pie charts show cost distributions for 350 bar and 700 bar Type IV single-tank compressed hydrogen systems at 500,000 units. See DOE Fuel Cell Technologies Office Record 15013.


Finally, DOE has determined potential pathways to reduce the cost of compressed tanks. This includes reducing the cost of carbon fiber composites and/or developing lower cost alternative fiber reinforced composites, better utilizing and therefore reducing the amount the fiber reinforcement included in the tank, and reducing the amount and cost of balance of plant components. This chart shows one potential cost reduction strategy for 700 bar compressed systems.

In truth, I was expecting someone to reply that 1 million cubic liters of hydrogen is not enough to supply even one ocean-going ship.  Is it?  The SpaceX idea is no crazier than the mid-ocean seaports suggested by others.  It simply has a brand — with an (almost) working prototype!
And discussion is preferred to stay in relevant topics.

I'm pretty sure rocket fuel to the future Spacex floating spaceports will be supplied by ships, not the other way around.

Haha. Yes, an example of why I was hoping for a discussion!  I guess the question becomes: how far could an ocean-going ship travel using 30,000kg of hydrogen?

World's First HightTemperature Ammonia-Powered Fuel Cell for Shipping
https://techxplore.com/news/2021-03-world-high-temperature-ammonia-powered-fuel-cell.html

At present, hydrogen is the primary focus in the area of sustainable energy: there are plans in place to use hydrogen to fuel buses, commercial vehicles, and even cars. However, the Fraunhofer Institute for Microengineering and Microsystems IMM in Mainz is working on another promising possibility. As part of the ShipFC project, the Fraunhofer Institute is collaborating with 13 European consortium partners to develop the world's first ammonia-based fuel cell for shipping. Fraunhofer's researchers are responsible for developing the catalytic converter, which prevents the production of emissions that would harm the climate.

When used as fuel for ships with electric engines, ammonia is as eco-friendly as hydrogen, but easier and safer to handle.

The ShipFC project is intended to prove that the new emission-free propulsion technology works safely, reliably, and smoothly, even in large ships and on long voyages. The project is being coordinated by NCE Maritime Cleantech from Norway, an organization that aims to develop eco-friendly technologies in the maritime sector.

The advantages of ammonia

... "Ammonia has significant advantages over hydrogen. Hydrogen has to be stored at -253 degrees Celsius as a liquid, or at pressures of around 700 bar as a gas. Liquid ammonia can be stored at a reasonable temperature of -33 degrees Celsius at standard pressure, and +20 degrees Celsius at 9 bar. That makes storing and transporting this energy carrier considerably easier and more straightforward."



... Ultimately, the only end products are water and nitrogen. An optimal reaction process will not even produce environmentally harmful nitrogen oxides.

... "We see ammonia not as a direct competitor to hydrogen, but rather as an additional option in the area of sustainable energy. With its storage advantages, this environmentally friendly technology for power generation certainly has a role to play. Using it in ships is just the beginning."

The IMM team is planning to complete an initial, small prototype by the end of 2021, to be followed by an actual-size prototype by the end of 2022. In the second half of 2023, the first ship with an ammonia-powered fuel cell will put out to sea—the Viking Energy, a supply vessel owned by the Norwegian shipping company Eidesvik. After that, other types of vessels, such as cargo ships, will be equipped with ammonia-powered fuel cells.

A huge container ship has accidentally blocked the Suez Canal, one of the world’s most important shipping lanes
https://www.theguardian.com/world/2021/mar/24/huge-container-ship-blocks-suez-canal-evergreen


https://www.vesselfinder.com/?imo=9811000

https://mobile.twitter.com/jsrailton/status/1374468169784459267

Ever Given, one of the largest cargo ships in the Suez Canal, has been stuck for almost a day.

The 200-foot-wide, 1,300-foot-long cargo ship has caused a massive logjam in one of the world's most important trade routes.

The ship had traveled through Taipei and Malaysia and had planned on arriving in the Netherlands on March 31 before winding up perpendicular and blocking the canal and  hundreds of cargo ships from both sides

Pictures and maps below show the state of the bottleneck.

Massive container ship EVER GIVEN stuck in the most awkward way possible.

Ongoing for hours.  Every tug Egypt could spare appear to be trying to pull it free.





A zoomed-in shot shows the tiny excavator used earlier to try to un-wedge Ever Given from the Suez Canal bank it is stuck on.

Mega-traffic-jam

https://mobile.twitter.com/TankerTrackers/status/1374481630505541634

... a lot of fully-laden tankers blocked from traversing in either direction. Tankers carrying Saudi, Russian, Omani and US oil are waiting on both ends.

Update: A severe dust storm and poor visibility are to blame for the 220,000-tonne, 400-meter (1,312 feet) container vessel turning sideways near the Southern end of the canal on Tuesday morning.

Egyptian officials at the Suez Canal Authority confirmed they are still trying to refloat the ship, named Ever Given, after it ran aground on its journey from China to Rotterdam in the Netherlands.

Several rescue attempts to dislodge the ship have so far failed.

Shows up on Sentinel playground. That's a pretty big screw up in these days of radar and GPS.

And the image shows it is on a straight part of the canal, not on one of the 8 major bends.

Definitely a major whoops.

Slow But (Almost) Ready – Suez Salvage Team May Be Postponed 5 Or 6 Days
https://gcaptain.com/smit-suez-salvage-team/

... A rough estimate shows the blockage is snarling about $9.6 billion worth of traffic a day, based on calculations from Lloyd’s List that suggest westbound traffic is worth around $5.1 billion a day and eastbound traffic approximately $4.5 billion

On Wednesday, 185 vessels were waiting to cross the canal, according to shipping data compiled by Bloomberg, while Lloyd’s estimates there’s 165.

About 34 container vessels chartered by Maersk Corp. and other shipping lines are either stuck in the canal or en route, according to project44. Preliminary reports show 10 crude tankers carrying a total of 13 million barrels could be affected by the disruption, according to Vortexa Senior Freight Analyst Arthur Richier.

It’s still in the same position as when it ran aground, according to Inchcape.

-------------------------------------

Ever Given, the massive cargo ship that ran aground in the Suez Canal, could take 'weeks' to clear
https://www.cnbc.com/amp/2021/03/24/ever-given-a-massive-cargo-ship-is-still-stuck-in-the-suez-canal.html

... "We can't exclude it might take weeks, depending on the situation," said Peter Berdowski, CEO of Dutch company Boskalis. Berdowski, whose company is helping in the salvage efforts, made the comments on Dutch television, according to Reuters.

At 8:30 a.m. ET Bernhard Schulte Shipmanagement, which is the technical manager of the vessel, said an earlier attempt to re-float the vessel had failed, and that another re-float attempt would be made later on Thursday.

To make matters worse the whole container shipping industry is already struggling handle the volume of pandemic-era cargo. 

When Suez Canal is eventually cleared there is a long queue of vessels heading both directions and reaching their already congested destination ports all at the same time. This will force them to change port rotations and omit some ports because they cannot get berthing windows. Expect delays and additional costs.

Obviously things will be very different if the canal is cleared tomorrow or in a fortnight.

Those ships cannot stay there, it's not the safest place to park a ship that's carrying that much stuff.   Not really.   Going round the Cape of Good Hope (or Cape of Storms) will add two weeks to the journey, but will increase the wear and tear on the ships and a few containers will be lost due to passing those sea lanes at this time of year.   It should take some time for the full cost to be measured.

I do like to check in at the Barents Observer (Norwegian) from time to time.   Possibly more appropriate in Northern Sea routes, but ... 

Making fun of Suez traffic jam, Rosatom promotes Russia's Arctic route as an alternative

https://thebarentsobserver.com/en/industry-and-energy/2021/03/making-fun-suez-traffic-jam-rosatom-promotes-northern-sea-route

Quote
The Northern Sea Route provides much more space if you want to use your giant ships to “draw peculiar pictures” Rosatom jokes in another tweet and links an article showing the AIS track of “Ever Given” forming a giant penis in the Red Sea before entering the canal.

There are 3 sarcastic tweets in the post. 

Myself, definitely agnostic about Northern route versus other routes.   Will be interesting to see what small fraction of testing the waters via  shifting this year to northern route occurs, but possibly the real winner down the road will be the Belt and Road initiative.

Maritime Historian Sees 'Ominous' Signs That the Suez Canal Blockage May Take Time to Fix
https://www.cnbc.com/amp/2021/03/25/maritime-historian-sees-ominous-signs-that-the-suez-canal-blockage-may-take-time-to-fix.html

Former Merchant Mariner Sal Mercogliano said Thursday he sees new and ominous signs that the 220,000-ton mega ship blocking Egypt's Suez Canal may take a lot longer to remove than initially thought.

"One of the most ominous things we are seeing, right now, is the parent company, Evergreen, has started to route two of their vessels around Africa," Mercogliano said. "That's telling us this may take a lot longer than they were initially expecting."

Mercogliano explained with that extended route, "you're talking about adding 3,500 miles on a route from Singapore to Rotterdam, you're talking about 12 to 14 days."

... while the Ever Given's misfortune has already impacted oil prices, factories might be next.

"There may be production plants, automobile factories, for example, will have to shut down, waiting to get parts," he said. "We don't live in a society today where we store a lot of parts."

------------------------------------------

Shipping experts remain concerned about the situation, with a CEO of a salvage company saying that the ship was "stuck rock solid."

The senior canal pilot at the Suez Canal Authority (SCA) told CNN Wednesday that re-floating the massive vessel is "technically very complicated" and could take days

... Dredgers are hard at work removing sand and mud from the bow of the ship -- and they will need to move between 15,000 to 20,000 cubic meters (530,000 to 706,000 cubic feet) of sand in order to reach a depth of 12 to 16 meters (39 to 52 feet), which could allow the ship to float, the SCA said on Thursday.

-------------------------------------------------

Shipping Backing Up; Rerouting
https://www.theguardian.com/world/2021/mar/26/suez-canal-ship-stuck-crisis-shipping-companies-rerouting-blocked-ships



The Japanese owner of a container ship that has been blocking the Suez canal for more than three days says it aims to free the vessel by “tomorrow night Japan time” but cannot guarantee that the effort will be complete by then.

The Japanese firm Shoei Kisen said the refloating work was ongoing but no firm end point was yet in sight. “We don’t have an estimate for when the work will succeed,” a spokesperson told local media.

... Seven tankers carrying liquefied natural gas (LNG) were diverted on Friday after the blockage caused traffic to be suspended.

Three of the tankers were being diverted towards the longer route around Africa, via the Cape of Good Hope, the data intelligence firm Kpler said, adding that most of the diverted tankers originally destined for Suez canal were now headed elsewhere.

“A total of 16 LNG vessels’ planned transit via the Suez canal will be affected if the congestion persists until the end of this week,” said Rebecca Chia, a Kpler anlayst based in Singapore.

... The international shipping company Maersk said on Friday it was “looking at all alternatives” for its nine container ships stuck in the queues.

“Everyone is making contingency plans as we speak,” said Peter Sand, chief shipping analyst at BIMCO

... “If you go to Suez you might expect to be 20th or 30th in line perhaps because there are about 50 ships in each direction every day,” he said. “But now you could be number 250 so that means you will be waiting three to four days to get through even when it reopens.”

Maersk’s main international rival, Hapag Lloyd, was also reported by Agence-France Presse to be considering sending shipping round the Cape of Good Hope, on the southern tip of Africa, in order to ensure that goods could reach Europe without even greater delays.

Suez Blockage Sets Shipping Rates Racing, Oil and Gas Tankers Diverted Away
https://www.reuters.com/article/uk-egypt-suezcanal-ship-idUKKBN2BI0G3



Black Sea to Mediterranean fuel shipping rates jump as traders try to bypass blocked Suez canal

... The cost of shipping clean products, such as gasoline and diesel, from the Russian port of Tuapse on the Black Sea to southern France increased from $1.49 per barrel on March 22 to $2.58 a barrel on March 25, a 73% increase, according to Refinitiv.

The shipping index benchmark for LR2 vessels from the Middle East to Japan, also known as TC1, had climbed to 137.5 worldscale points as of early Friday, compared with 100 worldscale points last week, said Anoop Jayaraj, clean tanker broker at Fearnleys Singapore.

Similarly, the index for freight rates for Long-Range 1 (LR1) vessels on the same route, known as TC5, stood at 130 worldscale points on Friday, up from 125 at the end of last week. Worldscale is an industry tool used to calculate freight rates.

Sailing around the Cape is in effect a capacity reduction on the affected trade lanes. This will cause problems because the container market is already squeezed hard.

I remember reading somewhere (possibly here) about scattered problems with the new low sulfur bunker fuel.   

Myself, I found out that for automotive; that running the E-85  fuel in a company vehicle can cause some ragged performance and noise during the winter.  And people related their tales to me of their problems also.   (I know apples and oranges)   

Quick search with articles from 2017 - 2020  yielded
marked increase in microbial growth

https://www.bimco.org/news/priority-news/20200819-industry-survey
Quote
increased sludge discharge, clogging of fuel pipes, preheaters, fuel separators and fuel filters, fuel pumps getting stuck, problems with fuel injection and poor ignition of fuel oil. It also focuses on other issues regarding incomplete combustion, wax appearance and increased wear and tear of cylinder liners. These are problems that may lead to loss of propulsion and/or black out.
The survey indicates global challenges with fuel characteristics and limits being off specifications most frequently when it comes to total sediment, aluminium plus silicon, pour point, ash, flash point, acid number and viscosity.

It also indicates that most common operational problems experienced are increased sludge deposits and wax appearance after switching to the compliant fuel oils with a sulphur content not exceeding 0.50%.

Lastly, the survey indicates that when commercial fuel oil samples are tested after bunkering, sulphur content is among the most frequent parameters to be indicated as off specifications and consequently, an indication of potential non-compliance with MARPOL annex VI.

and similar at
https://www.maritime-executive.com/article/bimco-survey-reveals-widespread-problems-with-new-low-sulfur-fuels

Of course there are numerous other possiblities that caused or contributed to.    Let's hope it was not a fisticuff, that would make two occasions of things going off the rail in Egypt in a short time (the rail crash that just happened).

Releasing Container Ship From Suez Canal Could Capsize It
https://www.thedailybeast.com/releasing-container-ship-from-suez-canal-could-capsize-it

While the global shipping industry bleeds $400 million each hour the massive Ever Given container ship stays stuck in the sand of the Suez Canal, an elite team of salvors on the ground in Egypt is facing an entirely different problem: How do you make a top-heavy ship stuck in shifting sands weigh less without capsizing it?

... “The worst case is that the ship is presently supported over her bow and stern areas, meaning possible sags in the middle.” ... “The risk is that it could also become top-heavy and capsize,” Captain John Konrad, founder and CEO of gCaptain shipping industry website, said. “And that would be catastrophic.”

But before anyone can even think of lightening the massive vessel—which is 1,312 feet long and 194 feet wide, with 50 feet of the ship below the water—they would need to download the schematics of the ship and run them through a series of computer-generated programs to determine what offloading will do to the balance. And then, they would have to somehow get a maritime crane to Egypt since the country does not own one tall enough to reach the top of the Ever Given’s 20,000 containers.

The information used to determine how to lighten the 200,000 metric-ton ship enough to nudge it out of the sand, which buries the vessel a little more with each passing tide, will be largely based on the ship’s own records—assuming they are correct and were not fudged to pass what the Maritime Anti Corruption Network once called the most corrupt port system in the world.

Ship's data so far shows it was also traveling 13 knots in an 8 knot speed zone when the accident happened.

Several salvors have also said the most likely cause was a blackout power outage that compromised steering just as the wind gust came up. Coincidentally, this same ship was involved in an accident in Hamburg in 2019, when its owners rammed into a ferry and destroyed it. They had blamed the accident on a loss of steering power and high winds back then, too.

Salvors say the next opportunity to move the ship will be during spring tides on Sunday and Monday. If that doesn’t work, it could take weeks to dig her out of the sand, hopefully while keeping her upright and intact.

Freighter Rams Ferry
https://amp.mopo.de/hamburg/frachter-rammt-faehre-knapp-an-der-katastrophe-vorbei-32016794?__twitter_impression=true

A huge container ship, a tiny jetty and in between a small Hadag ferry: on Saturday morning there was a loud bang at the Blankenese jetty. The freighter “Ever Given” collided with the ferry “Finkenwerder ”, which is now a total loss (MOPO reported). There are now many indications that the strong wind caused the crash - and only chance prevented a major accident.

Fortunately, there were no passengers on board

At the time of the collision, wind force seven (32–38 mph 50–61 km/h) prevailed off Blankenese - with gusts of force eight! Apparently too much for a ship the size of the "Ever Given". Because at Blankenese, the freighters usually travel at six knots - too slow to "weather" strong winds, as it is called in the language of seafaring.

In addition, the wind was blowing from the south-west, i.e. diagonally from the side - and pushed the tall ship towards the north bank of the Elbe.

Although two pilots were on board to support the captain, as is required in Hamburg, and even though the freighter was attached to the tug, the tall ships are very vulnerable in strong gusts and, according to insiders, difficult to control.

“It's like black ice when driving a car,” explains an experienced pilot to MOPO. "You can only be lucky there."

Oil Jumps 4% On Fears Suez Canal Blockage May Last Weeks
https://mobile.reuters.com/article/amp/idUSKBN2BI041

NEW YORK (Reuters) - Oil prices rose more than 4% on Friday on worries global supplies of crude and refined products could be disrupted for weeks as workers try to dislodge a giant container ship blocking the Suez Canal.

"Today the market is up again as traders in a change of heart decided that the Suez Canal blockade is actually becoming more significant for oil flows and supply deliveries than they previously concluded," said Paola Rodriguez Masiu, Rystad Energy's vice president of oil markets.

The Suez Canal stepped up efforts on Friday to free the stuck mega vessel, after an earlier attempt failed. Efforts to free it may take weeks, with possible complications from unstable weather.

Of the 39.2 million barrels per day (bpd) of total seaborne crude in 2020, 1.74 million bpd went through the Suez Canal, according to data intelligence firm Kpler. Additionally, 1.54 million bpd of refined oil products flow through the canal, about 9% of global seaborne oil product trade, Kpler said.

... At least 237 ships were waiting for the Ever Given to be cleared, including vessels near Port Said on the Mediterranean Sea, Port Suez on the Red Sea and those already stuck on a lake midcanal, said Leth Agencies, which provides services for the canal.

Using data from Automatic Identification System trackers on ships at sea, data firm Refinitiv shared an analysis with the AP showing that over 300 ships remained en route to the waterway over the next two weeks.

Sikorsky S64 sky crane heavy lift helicopters were designed for unloading container ships.  They need to get a couple of those put to work and they can unload that ship and lighten the load to float it high in no time.

someone's been figuring it out on the back of a napkin ...

How to Free the Ever Given—Using Buoyancy Force!
https://www.wired.com/story/how-free-ever-given-using-buoyancy-force/amp

... They need to remove a total mass of 23 million kilograms, that would be equivalent to ~605 containers—the Ever Given can hold 20,000 containers. ... How do you get a container off a ship in the middle of a canal? A heavy lift helicopter? That would work, but how long would it take? Let's say the helicopter can remove one container every 30 minutes. I mean, this seems like a reasonable time, since you have to fly over and then hook up a container then unhook it. Finding a level place for 600+ containers might be a trick. That would put a total unload time of 12 days (day & night).

The Big, Stuck Boat Is Glorious
Quote
I’m obsessed with the dang boat because people like me and you are not really supposed to be aware of what boats like her are up to. You’re not supposed to think about, or even notice, global freight, but the Ever Given has made cartoonishly noticeable some of the crucial infrastructure of global capital, which is usually invisible in most people’s daily life. She has done so with an absolutely sublime visual gag, improved by every new detail about the problems the ship is causing and every new photo of the impotent human measures being undertaken to fix them. ...

Truly massive shipping requires equivalent equipment to move.  That equipment is installed in very few places in the world.

Once there is a problem, it becomes apparent that places like the canal have no portable infrastructure to deal with it.

As a result of this issue things may change.
Being right too soon is socially unacceptable.

global trade is way too sensitive to minor disruptions. Just in time manufacturing has become we have to shut down car production due to a lack of computer chips. All of a product should not be made in the same region of the world. Multiple suppliers is better. Some stock on hand is a good thing. Two or three major competitors is not enough. Basically reverse most business trends of the last 30 years to fix things.

I got confused for a moment, and thought this was the Humor thread.

In 1979 I waded in Lake Timsah (City of Al Ismailiya) - near the canal's mid-point.  I viewed the canal from a "defenders of the canal during WWI" monument on a hill a few kilometers north of the city (with Egyptian soldier 'guides' - they made sure to point out the damage [made by guess who] inflicted during the 1967 Six Day War).  I later took a bus from Al Ismailiya (north) to Port Said, and saw the canal occasionally. 

The Ever Given is stuck near the southern (Red Sea) end of the canal.

Despite suggestions that the grounded 20,000 teu Ever Given could soon be moved by salvors, container lines' are warning the backlog of ships and requirement to redirect services mean the disruptions could be felt throughout the second quarter.

The world's top two box lines join others in diverting ships round Cape of Good Hope and warn of supply chain disruption ahead as Maersk begins to reject bookings

Cheniere and Shell Oil Tankers Change Course to Avoid Suez Canal as Ships Divert Routes
https://www.cnbc.com/amp/2021/03/27/suez-canal-cheniere-and-shell-fuel-tankers-change-course-to-avoid-logjam-as-oil-tankers-divert-routes.html

Companies are scrambling to reroute shipping vessels to avoid the logjam at the Suez Canal, including at least two U.S. ships carrying natural gas for Cheniere and Shell/BG Group, according to data provided by MarineTraffic and ClipperData.



At least ten tankers and containerships are changing course as the Ever Given, one of the world's largest containerships, remains stranded across the canal along Egypt, MarineTraffic spokesman Georgios Hatzimanolis told CNBC in an interview.

According to MarineTraffic, there are 97 vessels stuck in the upper portion of the canal, 23 vessels waiting in the middle and 108 vessels in the lower portion. The logjam stretches through the Red Sea, past the Gulf of Aden,  all the way to the Border of Yemen and Oman.

Suez Canal: Syria 'Rations' Fuel as Efforts to Free Stuck Ship Fail
https://www.theguardian.com/world/2021/mar/28/suez-canal-ever-given-stuck-ship-syria-rations-fuel

Syrian authorities say they have begun rationing fuel as the blockage of the Suez canal stretched into a sixth day, delaying vital shipments and worsening the country’s oil shortages.

Syria’s oil ministry said Saturday the trade route blockage had affected oil imports and slowed arrival of a ship carrying fuel and oil products from government ally Iran.

Pending a resolution, “the ministry is rationing the distribution of available oil products” to assure the continuity of essential services, such as bakeries and hospitals, the ministry statement said.

Oil minister Bassam Tomeh told state TV the cargo was due to arrive at the port of Banias on Friday. He added that if the blockage at the canal persisted, the ship may re-route around the southern tip of Africa, an expensive detour many companies have been forced to consider due to the blockage.

Before Syria’s war, the country enjoyed relative energy autonomy, but in the past decade an estimated $91.5bn in revenue has been lost from hydrocarbons, Syria’s oil minister said in February.

Pre-war production was 400,000 barrels a day, compared with just 24,000 in 2019.

Up to 80,000 barrels a day used to come from Kurdish areas outside government control, where more than 90% of the country’s reserves are located.

Nice article in the Financial Times about the hydrodynamics of the situation.

There is a bank effect that can cause the ship to yaw. The bigger the ship, the more pronounced the effect.

Egypt’s President Orders Preparations for Unloading the Ever Given Blocking the Suez Canal
https://www.nbcnews.com/news/amp/ncna1262271

Lt. Gen. Osama Rabie told Egyptian television channel Extra News the country's President Abdel Fattah el-Sissi had ordered the Suez Canal Authority (SCA) to prepare for all options, including taking some of the 18,300 containers off the 1300-foot long Ever Given, according to the Associated Press. Without elaborating, he added that officials had been in talks with the U.S. about the possibility of removing some of the cargo.

... Unloading some of the 18,000 containers from the towering ship would require special equipment, so the president authorized its acquisition even as dredging continued, Rabie said. So far, 27,000 cubic feet of sand have been removed from around the vessel to a depth of 18 meters, or about 59 feet.

"His excellency has ordered that we should not wait for the failure of the first and second scenarios to start thinking about implementing the third one," he said, referring to unloading.

Egyptian Prime Minister Mostafa Madbouly on Saturday thanked foreign partners for offers to help refloat the ship. The U.S. military has accepted a request for assistance to free the stuck ship.

... On Sunday, six more ships entered the canal, bringing the number of vessels trapped in the massive maritime congestion to 327, according to Leth Agencies.

New York’s Ever Given Crisis Is Bigger Than Egypt’s But Buttigieg Sits Silent

...

The cost of the mega containership Ever Given blocking Suez Canal traffic exceeds $9B a day but the cost of bringing these ships into poor and highly populated cities like Newark, New Jersey is much higher.

gCaptain (OpEd) When a mega containership like the Ever Given docks in the United States its over 20,000 TEU’s of containers are dumped on our cities and the environmental and health consequences and road damage is enormous. Our poorest children are dying, climate change is accelerating, and bridges are collapsing under the weight of heavy cargo boxes. This problem is bigger because in a few weeks the Ever Given will disappear from Suez but our cities will continue to be forever choked with boxes.

...

When a mega containerships like the Ever Given docks at Newark it’s over 20,000 TEU’s of containers are dumped on our cities and the environmental and health consequences and road damage is enormous.

In 2008 gCaptain first reported on the billions of dollars New York and New Jersey (or Los Angeles, Long Beach, Oakland, Savannah, Jacksonville, Miami…) taxpayers will spend for the privilege of letting mega containerships like the Ever Given dump tens of thousands of shipping containers at a time on our roadways and bridges which will tear up our roads and bridges and run over pedestrians and spew toxic emissions across our highway system.

...

In 1956, the Federal-Aid Highway Act, launched a  $25 billion program to build the Interstate Highway System. The law, which encouraged highway construction across the country by offering 90% of the funding needed to build them, left behind a horrific legacy. 

How horrific? Led by the infamous New York urban planner Robert Moses, cities took the money and paved highways along waterfronts and through neighborhoods. According to the Pulitzer prize-winning book The Power Broker, men like Moses ultimately brought down on the city the smog-choked aridity of our urban landscape, the endless miles of (never sufficient) highway, the hopeless sprawl of Long Island, the massive failures of public housing, and countless other barriers to humane living.

According to Stanford, toxic truck emissions costs the country over $790 billion per year in health care. 90% of city children breathe toxic air every day and smog kills 600,000 kids globally each year. That is over 1,600 dead children every single day.

The site is lobbying for local shipping but this is an interesting insight into all kind of facets we tend to ignore.

Pentagon: Suez Canal Stoppage May Impact Transit of Military Vessels
https://thehill.com/policy/defense/navy/545292-pentagon-suez-canal-stoppage-may-impact-transit-of-military-vessels?amp

Pentagon officials confirmed Sunday that the ongoing stoppage of traffic caused by a grounded container ship in the Suez Canal would affect the movement of U.S. military vessels, but stressed that the Defense Department had alternative means of supporting operations in the area.

... "We are not going to talk about specific operational impacts. The Suez Canal is an essential maritime choke point, and the longer passage is suspended, the more impact it will have to civilian and military transits. However, we have alternate capabilities to mitigate impact and support to our operations in U.S. Central Command's area of responsibility throughout any extended blockage," said Rebecca Rebarich, a public affairs official with the Navy.

"If more and more ships are going along the coast of Africa because of this incident, security arrangements would need to be tightened" around areas where piracy is known to occur, especially the waters surrounding Somalia and Yemen, said Paul Sullivan, an international security expert and professor at the National Defense University. ... "It is time to rethink and bolster international security arrangements related to these choke points. They are called choke points for a reason," he added.

Ever Given Ship Refloated After  Blocking Suez Almost a Week
https://www.theguardian.com/world/2021/mar/29/suez-canal-attempt-re-float-ever-given-delay-salvage-tugboats

The huge container ship MV Ever Given has reportedly been freed from the banks of the Suez canal, raising hopes that the vital waterway will soon reopen and global shipping backlogs will be cleared.

After almost a week of failed attempts to free the vessel, multiple reports on Monday morning said that it had been dislodged from its position lodged on the bank of the canal. Inchcape added that the ship was now being secured.

The 400-metre (1,300ft) long Ever Given was successfully re-floated at 4.30 am local time (0230 GMT) and was being secured, Inchcape, a global provider of marine services said on Twitter.

Video posted on social media appeared to show the ship’s stern had swung around, opening space in the canal.

https://mobile.twitter.com/jsrailton/status/1376377412859142149



At least 369 vessels are waiting to transit the canal, Rabie said, including dozens of container ships, bulk carriers, oil tankers and liquefied natural gas (LNG) or liquefied petroleum gas (LPG) vessels.

https://www.cnbc.com/amp/2021/03/29/cargo-ship-blocking-suez-canal-has-been-refloated-says-inchcape.html

Experts told CNBC that problems caused by the Suez blockage will not immediately ease when the Ever Given is freed. ... this is an enormous traffic jam, which is at both ends of the canal," ... "This will take quite awhile for the whole supply chain to get back to normal and that's gonna have an impact on manufacturers, retailers right across the board," said Huxley.

Container ship in Suez wrenched free, says canal services firm
Quote
SUEZ, Egypt (AP) — Salvage teams on Monday set free a colossal container ship that has halted global trade through the Suez Canal, a canal services firm said, bringing an end to a crisis that for nearly a week clogged one of the world’s most vital maritime arteries.

Helped by the peak of high tide, a flotilla of tugboats managed to wrench the bulbous bow of the skyscraper-sized Ever Given from the canal’s sandy bank, where it had been firmly lodged since last Tuesday.

After hauling the fully laden 220,000-ton vessel over the canal bank, the salvage team was pulling the vessel toward the Great Bitter Lake, a wide stretch of water halfway between the north and south end of the canal, where the ship will undergo technical inspection, canal authorities said.

Satellite data from MarineTraffic.com confirmed that the ship was moving away from the shoreline toward the center of the artery. ...

More containers have fallen off ships in the past four months than are typically lost in a year. Blame heavy traffic and rolling waves.
...
All told, at least 2,980 containers have fallen off cargo ships in the Pacific since November, in at least six separate incidents. That’s more than twice the number of containers lost annually between 2008 and 2019, according to the World Shipping Council.

You can blame the weather, a surge in US imports tied to the pandemic, or a phenomenon known as parametric rolling.
...
Plus, the ships are packed. “Not only do we have large vessels, bad weather, but we have, in many cases, vessels that are chock-a-block full,” says Jensen, the shipping consultant. A full container ship can be the length of four football fields, able to carry as many as 24,000 20-foot-long containers stacked five or six high. These are more likely to experience a phenomenon called parametric rolling, a rare but scary violent motion that can send blocks of containers tumbling to deck—or into the sea. ...

World’s first hydrogen cargo vessel set for Paris debut
Wednesday, 07 April 2021
Robin Whitlock

European innovation project Flagships will deploy the world’s first commercial cargo transport vessel operating on hydrogen, plying the river Seine in Paris with the vessel’s operations due to start sometime this year.

The hydrogen cargo transport vessel will be owned by French inland shipowner Compagnie Fluvial de Transport (CFT), a subsidiary of the Sogestran Group. The company is currently developing a new business for urban distribution with transport vessels in the Paris area.

The vessel will operate on compressed hydrogen produced from electrolysis, enabling not only zero-emission operations, but also creating a solid base for more local zero-emission transport, both at sea and on land. The power generation system for Zulu will be supplied by ABB Marine & Ports, with fuel cells from Ballard. LMG Marin is responsible for detail design drawings, with hydrogen provided by suppliers in the Paris region.

Ever Given ship forbidden to leave the Suez Canal until its owners pay up to $1 billion in compensation for the chaos it caused

The figure would cover the expense of the equipment and machinery used to clear the way and damage to the canal itself by the dredging while also compensating about 800 people who worked to release the 200,000-ton ship, Rabie said.

It would also refund the costs from the blocking of the canal, which ended up causing an epic traffic jam of more than 400 ships on either side of the channel. ...

Something else bottling up another waterway ...

Cracked Memphis Bridge Indefinitely Closed, Disrupting Supply Chain
https://www.npr.org/2021/05/12/996407481/cracked-memphis-bridge-remains-indefinitely-closed-disrupting-supply-chain



Traffic on and below a major bridge over the Mississippi River near Memphis, Tenn., could be halted for several days or longer, causing significant disruptions to motorists and shipping, officials said Wednesday.

Authorities in Arkansas and Tennessee, along with the U.S. Coast Guard, indefinitely stopped all traffic related to the Hernando de Soto Bridge on Interstate 40 after inspectors discovered a crack in the steel structure Tuesday, and Tennessee officials said repairs could take some time.

The bridge connects Memphis to West Memphis, Ark., and is above a crucial waterway for barges transporting crops to export markets. Crews have begun emergency repairs.

Arkansas Department of Transportation Director Lorie Tudor said it had the potential to become a "catastrophic event," adding, "The bridge was closed to vehicular traffic and the river was closed to barge traffic as a safety precaution."

Authorities said barge traffic can't resume unless engineers determine that the bridge can stand on its own despite the rusting crack. They said it could take a couple of weeks just to complete a full inspection of the nearly 50-year-old bridge.

Inspectors have to figure out whether the bridge can hold its own weight and the weight of construction crews, according to The Associated Press.
