TROUBLE AHEAD ??? : Expanded Panama Canal Fundamentally Flawed Says Veteran Ship Pilot


Image: Panama Canal

Captain Jose Claus, a Panama Canal pilot with 22-years of experience guiding ships along this vital passage, strongly believes the locks for the new Panama Canal have a fundamental design flaw that may have extraordinarily far-reaching and highly negative implications. 

In short, he believes they are under-engineered for the task they are about to perform.

Initial engineering studies for the new Panama Canal brought engineers to Port of Antwerp to visit the largest Post-Panamax locks in the world, Berendrecht and Zandvliet. 

 At these locks, tugs are used maneuver the ships in and out of the locks rather than locomotives (mules). Both locks measure 1,640 feet long and are 223 feet wide and 186 feet wide, respectively.

The dimensions of the locks in Belgium are critically important because not only do they consider the maximum size of the vessel that will transit, but also the maneuvering tugs which will accompany these vessels alongside. In the case of Berendrecht, the added width of the lock allows much larger Post-Panamax vessels to transit through with the assistance of tugs both fore-and-aft, as well as port and/or starboard. Under flat calm conditions, a Post-Panamax ship could probably transit through the Zandvliet lock as well, however they don’t because of the difficulties in keeping the ship laterally centered in the lock while hooked up to the tugs fore-and-aft.

This is the situation facing the new Panama Canal which will measure 1,400 feet long and 180 feet wide. With new Panamax-sized ships designed to have a maximum beam of 161 feet, that leaves only 19 feet to spare on either side of the vessel, which is about half the beam of a typical tugboat. Tugs will simply not be able to operate alongside Panamax vessels transiting the new Panama Canal.

There are other consideration as well, notes Captain Claus.

“The new Panamax lock on the Caribbean side is aligned more in the west-east direction which puts transiting vessels more broadside with respect to the prevailing winds. In our dry season, 21 knots is normal and some days reach 30 knots, however in Antwerp, thenavigation regulations note that maneuvers should be postponed above Beaufort Force 5, or 21 knots of wind.”
Considering the windage inherent to LNG tankers and large containerships, this is a major consideration.

Without the use of locomotives such as those currently being used, Captain Claus is deeply concerned the new Panamax ships will not be able to be safely maneuvered through the canal. “Instead of an hour and a half transit times, we may be looking at four hours in order to do this safely,” he notes in a phone call.

More than doubling the transit times would subsequently half the number of ships that are able to transit and potentially ruin the business case for the canal, he notes.

“Major delays on the Panama Canal would be catastrophic to Panama,” 
notes Claus.

And indeed the entire shipping industry. In speaking with a shipowner today, the biggest industry question is, “What will the rates be to use the canal once expanded?”

If Claus’ warning comes true, transits through the canal will fall while rates rise proportionally.

While "Flavor" is very subjective, and each country that grows mangoes is very nationalistic, these are the mango varieties that are the most sought after around the world because of sweetnesss (Brix) and demand.

The Chaunsa has a Brix rating in the 22 degree level which is unheard of!
Carabao claims to be the sweetest mango in the world and was able to register this in the Guiness book of world records.
Perhaps it is time for a GLOBAL taste test ???

Alphonso (mango)
From Wikipedia, the free encyclopedia

Alphonso (हापुस Haapoos in Marathi, હાફુસ in Gujarati, ಆಪೂಸ್ Aapoos in Kannada) is a mango cultivar that is considered by many[who?] to be one of the best in terms of sweetness, richness and flavor. 

It has considerable shelf life of a week after it is ripe making it exportable. 

It is also one of the most expensive kinds of mango and is grown mainly in Kokan region of western India.

 It is in season April through May and the fruit wei…

Mangoes date back 65 million years according to research ...

Experts at the Birbal Sahni Institute of Palaeobotany (BSIP) here have traced the origin of mango to the hills of Meghalaya, India from a 65 million year-old fossil of a mango leaf. 

The earlier fossil records of mango (Mangifera indica) from the Northeast and elsewhere were 25 to 30 million years old. The 'carbonized leaf fossil' from Damalgiri area of Meghalaya hills, believed to be a mango tree from the peninsular India, was found by Dr R. C. Mehrotra, senior scientist, BSIP and his colleagues. 

After careful analysis of the fossil of the mango leaf and leaves of modern plants, the BISP scientist found many of the fossil leaf characters to be similar to mangifera.

An extensive study of the anatomy and morphology of several modern-day species of the genus mangifera with the fossil samples had reinforced the concept that its centre of origin is Northeast India, from where it spread into neighbouring areas, says Dr. Mehrotra. 

The genus is believed to have disseminated into neighb…
