Strukton to help protect Venice from flooding

The Dutch engineering company Strukton is going to help protect Venice from flooding. Strukton Immersion Projects, the Strukton company specialised in tunnel immersion technologies, has been commissioned by Venice authorities to engineer and execute a storm surge barrier that will seal off the Venice lagoon in case of high water.

Storm surge barrier system

The storm surge barrier system is made up of movable barriers being constructed at the three entrances to the lagoon, near Lido, Malamocco and Chioggia. The barriers will only be closed in the case of extremely high water; the system is comparable to the Maeslant barrier in the Netherlands. The barrier will be made up of eight concrete caissons, each weighing 21,000 tons.

Venice spans a group of small islands in the middle of a lagoon. For centuries it has suffered flooding from the Adriatic Sea, but these floods are becoming more and more frequent. Not only is the sea level rising, the city is also sinking into the soft soil.

Strukton will perform this work for Clodia, an Italian contractor alliance, as part of the MOSE project (Modulo Sperimentale Elettromeccanico). Engineering will commence immediately. Work will be executed and completed summer 2014. Strukton specialises in immersion and has previously been involved in numerous tunnel projects, including the immersion of tunnel elements for the Busan-Geoje Link in South Korea and the Limerick tunnel in Ireland.
