Special intervention in S. Erasmo: new MV SC Pizzo – SC Bubacco line with underwater cable laying

Following the  black out on the islands of  Burano and  Torcello, E-Distribuzione spa assigned to us the management of immediate repairs with  the construction of a new line of 1,300 meters in 10 working  days. The new connection line that supplies  the islands of Burano and Torcello with an underwater cable made it possible  to restore the electricity service  to users on the islands.

Following the Customer’s emergency call,  PSC participated in the  joint technical table with E-Distribuzione, the Mayor,  the Fire-fighting brigade and the Civil Protection, with a view to setting up communication and interface 24/24h operational points in  Venice, Limena and Marghera. Moreover, PSC  managed the emergency  by restoring the  temporary electricity service with generators.

The PSC Group coordinated the vessels (5 pontoons simultaneously and  6 support boats), arranged the  logistics of the heavy vehicles (cranes, trucks, equipped vans, generators), and collaborated with the technical underwater operators,  cabin operators and  specialized cable jointers.
