Croatian Knowhow Vital Role In Saving Venice

 

 

Italian city of Venice is under serious threat due to the rise in sea level and sinking of land at an alarming rate. The MOSE project will protect the Venetian Lagoon from being submerged by the Adriatic Sea and protect the famous city of Venice and the neighbouring areas from flooding. MOSE, the Italian word for Moses, is an acronym for Modulo Sperimentale Elettromeccanico, which means Experimental Electromechanical Module. The name aptly alludes to the story of Moses parting the Red Sea.

After being successful at its tender to undertake the building of steel barriers/gates that are an important part of the very complex MOSE project, Brodosplit from the city of Split (Split Shipbuilding company) is well on the target and course to complete the building of 41 steel barriers worth 50 million Euro, reports the daily newspaper Slobodna Dalmacija. 2 barriers have been completed and are ready for delivery while 19 are in various stages of completion.
“The buyer requests high precision in the making of the steel gates and long-term anticorrosion protection. Very limited tolerances, the highest quality class and the amount of accompanying documentation make this Project much more demanding in technical-technological sense than what shipbuilding is. Brodosplit will deliver gates with dimensions 27-30 x 20 meters, 4.5-5 meters height and with weight of 300 tons.

Project is an integrated protection system consisting of a number of mobile gates that are capable of closing off Venetian Lagoon from the Adriatic Sea when the tide exceeds established level (110 cm) up to maximal three meters. These are mouths of Treporti, Malamocco, Chioggia and San Nicolo. For construction of steel gates for sea Mouth of San Nicolo, the tender is currently open and Brodosplit submitted its proposal.

A set-up of 78 gates designed as special reservoirs filled with air or water, is foreseen. They will lay at sea bottom when filled with water, and rise towards the surface to close the Lagoon entrances when filled with air. After air is released, they will get filled with water again and lie at the sea bottom. During these several hours, Venetian Lagoon would be closed and ships could not enter it freely.

Brodosplit is extremely proud of this Project, just as whole Croatia, because it will remain forever registered on the list of countries that participated in one of the biggest construction projects in Italian history with overall value of more than 7 billion euro and thus contributed to saving Venice from big problems caused by tide.

This project proves that Brodosplit is capable to build not only ships, but very complex and demanding steel constructions and that it can compete with majority of world shipyards with its knowledge and experience,” states on the Brodosplit/ Split Shipbuilding Co, website.

 

 

The natural-colour Landsat images above show some of the MOSE engineering efforts that are visible above the water line near the Lido Inlet. The top image was acquired on June 20, 2000, by the Enhanced Thematic Mapper+ on Landsat 7. The second image, from the Operational Land Imager on Landsat 8, was collected on September 4, 2013. In 2013, a curved breakwater stands just south of the inlet’s south jetty. On the lagoon side of the Lido Inlet, a new manmade island appears; it houses the buildings and plants that operate the gates, which are underwater in two arrays on either side of the island. On the north side of the inlet, a manmade harbour for small vessels includes a small lock system that allows boats to pass from the lagoon to the sea when the gates are raised.

Since the beginning of MOSE construction, five million cubic meters of sediment have been excavated from areas adjacent to the lagoon’s three inlets. The $8.8 billion dollar project has encountered some scientific, environmental, and political objections about disrupting the natural water exchange between the lagoon and Adriatic.
The Lido Inlet gates were successfully tested on October 12, 2013, and operators aim to have the MOSE system fully functional by 2016. Certainly, all indications are that Croatia’s Split Shipbuilding Company “Brodosplit” is keeping its role in the project to save Venice up-to-date and on time, having signed the contract to construct the steel floodgates with the Italian company Costruzioni Mose Arsenale, COMAR, in January 2015.
After international tender, Consortium Venezia Nuova decided that Brodosplit was the best tenderer among the strong competition and it was officially selected as builder of steel gates for the two mouths. Total project that will be executed by Brodosplit includes over 12,000t of built-in steel.

“Under threat of sea level rise, endangered architecture and numerous floods at Piazza San Marco and surrounding streets, Venice could become the dying relic. However, with Brodosplit in action there is a realistic and definite chance that this gem of culture in the Adriatic would be preserved for the centuries to come, “ Tomislav Debeljak, Brodosplit Chief Executive Officer, pointed out.
Well done, Brodosplit!

Croatia’s participation in saving Venice also has historically-emotional significance as several parts of the Dalmatian coast had once and for number of decades been taken over by the Republic of Venice (696 – 1797) where on the Island of Korcula, in 1254, Marco Polo was born to parents who were Venetian merchants living in the old town of Korcula for several of Marco’s early childhood years.
