New sealing complement for Venice

Venice, with a exuberant palaces along miles of gondola-traveled canals, has drawn visitors for centuries. Threatened by rising tides, a ancestral city has embarked on an engineering plan to safety a treasures for destiny generations.


The tenure MOSE, recalling Moses and a interruption of a Red Sea, is a quite good name for a plan directed during saving Venice and a Venetian Lagoon from a hazard of ever-high tides. Concerns that a flooding is removing worse since of tellurian warming meant that a vast infrastructure plan is one of a many critical in a city’s history.

The MOSE, assembled by a Ministero delle Infrastrutture e dei Trasporti – Magistrato alle Acque di Venezia (Ministry of Infrastructure and Transport – Venice Water Authority) by a Consorzio Venezia Nuova, is partial of a critical systemic module of measures mixing earthy invulnerability with replacement of a morphological balance of a whole firth ecosystem. The final and many critical component in a designed involvement to guarantee a firth area, a MOSE construction is now about 80 percent complete. It was preceded by a work module desolate anywhere in a universe for a distance of a area involved, a inlet of a problems tackled and a scale and characteristics of a measures implemented.

Scheduled to be finished in 2016 during an estimated cost of 5.5 billion EUR, a MOSE plan requires 78 mobile barriers to be commissioned during a Lido, Malamocco and Chioggia inlets, a gaps by that a waves enters a firth and that apart it from a Adriatic.

The barriers include of steel gates commissioned end-to-end and are used usually when there is a risk of flooding. The gates are routinely totally invisible, resting in special housings in a bed of a firth inlets. When high H2O is forecast, they are temporarily lifted to besiege a firth from a Adriatic Sea. When a waves goes down, a gates are returned to their housing in a seabed. Trelleborg has been really concerned in a MOSE plan with contracts to supply a plan with tailor-made sealing solutions and mixed buffer systems.

Trelleborg worked closely with a consultant engineer, Technital, during a pattern proviso as good as with one of a project’s categorical contractors, Clodia SpA. “For such a large-scale infrastructure project, it was critical that we source a arguable resolution that would mount a exam of time,” says Diego Zandolin from Clodia. “Trelleborg betrothed a hassle-free designation routine and proven functionality. Its buffer systems and bespoke sealing systems yield an ideal solution. “Trelleborg granted a state-of-the-art Super Cone and Arch fenders after overcoming a plea of provision a vast apportion of fenders in a quite brief turnaround time,” Zandolin explains. “It also supposing a sealing complement solutions while assembly some intensely perfectionist guidelines. Although we knew a Trelleborg complement was already proven globally, Trelleborg was means to tailor it to broach a custom-solution that would precisely accommodate a project’s needs. The palliate of designation for a complement was also a critical cause in selecting Trelleborg.”

Zandolin explains what his association was looking for: “We indispensable mixed made-to-order sealing complement solutions, and Trelleborg was means to accommodate a mandate with a multiple of rarely volatile healthy rubber Seismic Gina gaskets, a molded and handmade sign made to a top tolerances, as good as Omega seals.”

The sealed Gina gasket will be trustworthy to a barriers and act as a energetic seal, ensuring watertight protection, while a Omega sign will act as a delegate sign between a sectional elements of a mobile barriers.

Richard Hepworth, President of Trelleborg’s sea operation within Trelleborg Offshore Construction, comments: “We’re gay we could rise effective solutions for such a poignant project, one that will positively assistance guarantee a destiny of Venice.” He points to Trelleborg’s industry-leading operation of products, technical imagination and end-to-end support as pivotal factors in a project’s success.

The MOSE complement is being assembled in a Venetian Lagoon inlets, a spaces between a separator island by that a tides enter and exit a lagoon. There are 3 firth inlets, Lido, Malamocco and Chioggia (800 m, 400 m and 380 m wide, respectively). The inlets are delimited by prolonged jetties built between 1800 and 1900. These have been formally combined in a 1990s and so offer as support to a high H2O counterclaim system.
