sembra un akula

Mi sembra che sia il relitto dell'Explorer, un sommergibile sperimentale Americano, antecedente la prima guerra mondiale, se ricordo bene, era uno dei primi progetti dell'Ing. Holland, lo avevano provato proprio a Panama, ma non ricordo bene per quale motivo, era affondato arenandosi su un basso fondale.

Dovresti cercare in Internet c'è un sito in Inglese che ne parla, mi sembra sia il sito della ditta produttrice dei sommergibili classe H.

Vado a vedere se lo trovo poi ti dico.

Quando è stato scoperto?

 

 

...scoperto forse è un parolone, si nota abbastanza direi...

[Keltos]

Ciò che ha detto Luciano penso sia la verità.

 

Link sito Ansa

Sul sito dell'Elettric Company non l'ho trovato, quindi penso di aver letto, qualcosa, sul sito dove parla dell'ALLIGATOR, e della Guerra di Secessione Americana.

Quando ero sul sito e stavo leggendo forse avrei dovuto tenere il Link, peccato!!!

Trovato!!! , mi sbagliavo non è stato Holland il costruttore ma Julius Kroehl immigrato tedesco, molti anni prima, come vedrete, è davvero L'Explorer, usato a Panama per la ricerca delle perle. quello che dicono sia stato preso come modello da Jules Verne, per la storia di 20.000 leghe sotto i mari e il suo Nautilus del Capitano Nemo.

Posto tutto l'articolo storico in Inglese:

 

You will have to endure a bit more submarine history. After writing the four-part series on the submarine force, I read about another re-discovered Civil-war era American submarine, the "Sub Marine Explorer," the remains of which were found on the coast of Isla San Telmo, one of the Pearl Islands, off the east coast of Panama.

 

It was designed and built by Julius Kroehl, a German-immigrant engineer and Union naval officer in 1864-65. Sea trials and operational demonstrations in 1866 in New York harbor showed that it worked, that the number of surfacings could be made to equal the number of submergings.

 

What was unique about the boat was that the crew compartment was pressurized to whatever depth the boat achieved, thus allowing crew members to "lock out" submerged. The operational concept for the 36-foot long boat was that it would sail submerged into a harbor, then crew members would lock out and attach delayed-detonation explosives to ship hulls or piers.

 

Not understood at the time, was that a pressurized crew compartment committed the crew to a painful malady and potentially signed their death warrant.

 

Kroehl knew that the U.S. Navy, having decided to go with the "Alligator," would not fund construction, so he went into business with the Pacific Pearl Company, touting the boat as the means to harvest pearls from extensive pearl beds off the Panama coast. The boat was transported to Panama in 1866, and was used to work the pearl beds for three years.

 

There apparently was no problem with crew members surviving, but after a period of working for 10 straight days on a pearl bed 100 feet down, for four hours at a time, crew members became deadly ill. Kroehl, after one dive, had the same symptoms, and died. The cause was said to be a "fever," or malaria. (Kroehl had contracted malaria during the Civil War.)

 

In hindsight, the crew members' malady, and the cause of Kroehl's death, was the bends - an unrecognized hazard at the time - no provision was made for decompression as the boat ascended from the 100-foot depth.

 

"Sub Marine Explorer," abandoned and forgotten in 1869, is now a rusty hulk partially-buried in the sand. Marine archaeologists, lead by James Delgado, have surveyed the wreck, and are making an effort to round up funding to rescue the boat, and bring it to a facility where it can be investigated and preserved. The Warren Lasch Center in Charleston, where the CSS Hunley is being preserved, has been named as a possible location for the work.

 

Lieto di essere stato utile
