What is the status of MOSES in Venice?



With Wednesday's emergency flooding in Venice, where high water reached 187cm touching the historic peak observed during the 1966 flood, we returned to talking about MOSE, the imposing structure now under construction for over fifteen years to complete. repair the city from the high tide. According to its designers, MOSE, which stands for Electromechanical Experimental Bodies, is almost over: but even the last five years of its history are marked by long delays and unexpected events that have increased skepticism about a work that is already controversial.

Currently the work is being done at 94 percent, according to its builders, and the date announced for its commissioning is the end of 2021. Earlier on Wednesday, after high water, the Mayor of Venice, Luigi Brunjaro, reiterated the urgency of putting the plant into operation.

The latest delays are very recent. Only at the end of October was it actually postponed to a date to define a test that would require the complete abolition of one of the barriers that make up the moat dam, that of the port of Malamoko, one of the three passages linking the lagoon of Venice beside the sea, along with those of Lido and Yogogia. The problem was that the test saw vibrations considered dangerous, which caused the general test originally scheduled for November 4, the anniversary of the high water in 1966, to blow up.

The last phase of inspection of the ports of entry – what are called the 78 huge barriers that make up MOSE – from other port mouths were conducted between April and July this year. Roberto Borasso, Venice's Mobility and Transport Adviser, said last July that work was "done at 94 percent", adding that "on 29 October[[[[2018 ed] , when extremely high water of 156 centimeters was recorded, we might already have been able to use it. "

The next stage, after completing the tests on the last ports, should be the completion of the final systems of the system, which according toAnsa is scheduled for June 30, 2020, followed by the final phase of experimental management. It is estimated that the total cost of the project will reach 7 billion euros.

MOSES is one of the most famous Italian infrastructure projects of the last twenty years, built since 2003: initially, work was to be completed in 2014, but then the date was postponed several times for various obstacles. The most famous came in 2014, when a major investigation hypothesized a huge round of corruption offenses, including the arrest of former Veneto region president Giancarlo Gallan, who then negotiated a sentence of 2 years and 10 months. The realization of the offenses is entrusted to Consortia Venice Nuova, a union of local and national companies and co-operatives, which was the state's police station following the scandal.

Specifically, MOSE consists of a kind of huge floating pad installed on the three port mouths – ie. three passages – separating the Venetian lagoon from the sea: that of Lido, that of Malamoko, and that of Zigogia. To block the high tides, there are 78 entrance gates, ie metal wardrobes 18 to 29 meters wide, attached to huge concrete blocks at the seabed. Normally, the entrance gates remain stacked at the bottom, but they increase when the high tide exceeds the 110-cm threshold, protecting the lagoon. To facilitate the passage of boats, MOSE provides for navigation pools, or lock systems that allow entry and exit from the lagoon.
