UPDATE II – Neoliner Origin

This picture from a webcam at the Baltimore, Maryland harbor shows Neoliner Origin being welcomed and led into port by the seagulls. The seagulls are shown in the yellow circles. Others have disappeared behind the ship.

This article is an UPDATE to two previous articless having to do with using wind power on modern ocean-going cargo ships. The first article was posted on October 1, 2018 (Cylindrical Sails) and a First UPDATE to that article was posted September 18, 2020 (UPDate – Sails from Sweden).

The discussion in this Second UPDate article celebrates the arrival of a wind powered “Roll On – Roll Off” (Ro-Ro) vessel that arrived in the Port of Baltimore on 30 October 2025.

In line with the concept of an UPDate, a future discussion of the cylindrical sail concept may be found on The Maritime Page that may be found at https://maritimepage.com/rotor-sails-on-ships/. As discussed in that article the concept of cylindrical and rotating sails has been around since 1920. The concept continues to be studied and numerous ships have been fitted with cylindrical sails in the past two decades.

Regarding the sails being developed by Swedish company Wallenius Marine and Danish company KNUD E. HANSEN in the First UPDATE, they are reinforcing their position in sustainable shipping with the development of the Sleipner RoRo. The Sleipner RoRo may be fitted with “wing sails,” which are rigid aerodynamic sails.

This Second UPDate could have been written as a stand-alone article on the maiden transatlantic voyage of the Neoliner Origin, but I feel it is an UPDate to the original article regarding the concept of wind power for ocean-going cargo vessels.

The Neoliner Origin is a 5,300-ton sailing roll-on/roll-off (Ro-Ro) cargo ship especially fitted for carrying cars. It was commissioned by Neoliner, a French company and was designed by the French naval architecture firm, MAURIC. It is a medium-sized ocean going vessel, and is discussed by M. Jean Zannotini, the CEO of Neoliner in an interview which may be found at https://youtu.be/dUdaBnJ58jI . The interview also contains a description of the vessel and its purpose in combating global-warming which is driving climate change. The design of the Neoliner Origin reduces the emissions of it transatlantic voyage by 80% to 90% from a typical voyage for delivery of cars and machinery. Ocean shipping moves the vast majority of goods manufactured from the country of origin to markets around the world. According to the United Nations Conference on Trade and Development (UNCTAD) ocean shipping is responsible for 3% of the global greenhouse gas emissions.

Neoliner Origin’s propulsion is provided by two sets of sails mounted on two 90-meter (295 feet) masts. There is 3,000 square meters (more than 32,000 square feet) of total sail area. The ship’s speed under sail is 16 knots (more than 18 miles per hour). A ‘knot’ is the nautical term (nautical mile per hour) for the speed of a vessel. A knot is approximately equivalent to 1.2 miles per hour. It is noted that ocean cargo ships have an average speed of 18-20 knots.

The masts can be lowered/tilted (with sails furled as pictured in video) to less than half their height to enable the ship to pass under bridges as it enters and leaves ports. While in port the ship uses a diesel-electric hybrid propulsion system for maneuvering. This same diesel-electric hybrid system may be used if the sails are damaged during crossings. This was the case on the Neoliner Origin’s maiden voyage to North America and Baltimore as a storm at sea damaged the aft sails.

The following websites were visited and were utilized in the development of this article.

(*Just_A_Note) – Cold Moon / True Moon

It was the last full moon of the year – and the decade.

Our calendars and our clocks do not make any variance in the movement of the stars, or the planets, or their moons. Our clocks and calendars allow us to track the procession of the heavenly bodies, but they do not guide them. Never the less, when a celestial event happens on a meaning-filled date it is remarkable; that is in the sense that the juxtaposition may be remarked upon.

For me the 12th day of December is a meaning-filled date. When an event is forecast for that date for me it is remarkable.

So it was with the Full Cold Moon on an early morning of mid-December. I went outside and took my picture in the light of the last full moon of the decade just at the peak of its brightness.

Or so I thought.

Having herein proclaimed that the celestial bodies do not care about our watches or calendars, I must say I was 24 hours off.

I stood outside, bundled against the cold, watching the moon creep towards its zenith, and I thought its brightest. My watch told me that the time was approaching 12:15 AM on December 13^th. At that moment, I turned so that I was not in the Moon’s shadow and took my picture, with the full moon in the background masked by light clouds.

The peak of the full moon, I later discovered, had been a full day before on 12 December. I was standing outside on the morning of 13 December.

But this was not like the transit of Mercury which happens and then is over. If I missed the fullness of the moon on the 12th of December, I could still take my picture of me and the moon 24 hours later. And I could still declare that the event and the picture were meaningful to me.

A picture of me with the moon at the actual time of the event would be more preferable, but I was ok. It was a grand night. It was cold and partly clear. I could see the moon and a star or two shining through the thin clouds. I could hear the dogs in the neighborhood barking, perhaps at a fox, or a stray cat, or maybe at the moon.

And I was outside enjoying it all.

Just a Note – An Opportunity

Where there is hope – there is Opportunity.

In June of last year, we were told by NASA that the 14 year mission of Rover Opportunity might be coming to an end. The rover was caught in a planet-encircling dust storm. This did not allow light from the sun to reach the rover’s solar panels, and her battery were becoming drained.

This year NASA tried to get Opportunity up and running, but their best efforts did not work. NASA sent one more transmission to Opportunity on 12 February, 2019, but no response was received. The following day NASA announced that the mission was concluded.

At least the roving part is completed. Years will be spent by scientists and geologists and engineers pouring over the treasure trove of data sent back by Opportunity. All that information will improve the likelihood of another outstanding success in a future mission to Mars – or beyond.

If Opportunity had a middle name it would be Success. The rover was originally planned as a 90-day mission. Opportunity lasted for 14 years. Her sister rover, Spirit, lasted about half as long, but also well beyond her planned 90-day mission

Why mentioned them now, nearly 6 months after the conclusion of the mission? Because they are a model for success, and we should always talk about success. Plus I’ve been hoping that we would hear from her.

Maybe someday an astronaut will walk up and dust off her panels, and Opportunity will say, “Welcome to Mars”.

(*Just_a_Note) – Wallace Broecker

News sources around the world have reported the death of Wallace Broecker. As a climate scientist, he penned an article that was published in the journal Science in 1975. This article was among the early warning calls of the effect of atmospheric carbon dioxide (CO2) to cause a rise in the global mean temperature. Dr. Broecker titled the article “Are we on the brink of a pronounced Global Warming”. Through his article, and many others that followed, the term “global warming” has come into common use and is readily understood by all to imply a continuing rise in the global temperature to the point that it has a detrimental effect on the oceans, wildlife, agriculture, and human society.

As Broecker stated in his 1975 article, “… the exponential rise in atmospheric carbon dioxide content will tend to become a significant factor and by early in the next century [the ‘next century’ started in 2000] will have driven the mean planetary temperature beyond the limits experienced during the last 1000 years.”

Further in the article Broecker predicted, “As the CO2 effect will dominate, the uncertainty … lies mainly in the estimates of future chemical fuel use and the magnitude of the warming per unit of excess atmospheric CO2.” When any of us is outside we can see and often smell the exhaust of the continuing use, and increased use, of fossil (chemical) fuels by the world’s expanding population.

So when in his article Broecker asks, “Are we in for a climate surprise?”, the answer is both yes and no. Yes, it is happening, CO2 continues to clog our atmosphere. But no, in 2019 it is not a surprise.

(*Just_a_Note) – GIORDANO BRUNO

The most recent lunar eclipse on 20 January 2019 included the sighting of a meteor crashing into the disk of the full moon. The flash of the purported crash was captured by Jose Maria Madiedo, a Spanish astronomer who filmed the eclipse. After he reported it others verified a similar sighting.

On June 18, 1178 a similar sight was seen on a crescent moon. That event was recorded by Gervase of Canterbury, “the upper horn of the new moon seemed to split in two and a flame shot from it. From the midpoint of this division a flaming torch sprang up, spewing out, over a considerable distance, fire, hot coals, and sparks.” The description has been thought to have been the creation of the crater Giordano-Bruno. But that crater is estimated to be at least a million years old. The event seen by the monks is now thought to have been an earthly meteor that happened to be juxtaposed over the moon as it flashed through the sky.

In both these instances an “on-the-moon” survey would answer the question. In either case viewing the moon is a worthwhile past time in summer or winter.

As interesting as these events are, an important aspect of the history of science is caught in the web of the craters of the moon. Giordano-Bruno was an outspoken Italian philosopher in the second half of the 1500s. He was a proponent of an infinite universe (1584) which was at odds with the teaching of the powerful universities and church movements of the time. For his trouble to shake the minds of the youth into new paths of thought he was burned at the stake on February 17, 1600.

(*Just_A_Note) – Chang’e-4 cotton seed sprout

On Tuesday January 15, 2019 the China News Agency, Xinhua, reported that the Chnag’e-4 experiment of growing plants on the moon had ended. Seeds of cotton, rape seed, and potato cuttings as well as eggs of the fruit fly had been carried to the moon in the recent landing of Chang’e-4. They were part of an experiment to see if terrestrial plants could be coaxed to grow in an enclosed and protected environment on the surface of the moon. The experiment was enclosed in a heated canister. Sunlight to stimulate plant growth was directed into the canister through a tube. Cameras were included in the canister to record the plant growth. Within days of the landing on the far side of the moon, the world was excited to learn that one of the cotton seeds had sprouted and its small stalk was the first plant to be cultivated on the moon’s surface. However, it was the only plant in the experiment to germinate and grow. The plant did not fully develop. Now that the lunar night, during which the dark side will not receive sunlight, has begun in the current phase of the moon, the experiment has been terminated.
