Messina II 380 kV HVAC interconnector submarine cable crossing of the Strait of Messina, with associated mattress protection works along the subsea route.
Asso.subsea carried out mattress installation works on the Messina II interconnector to support and protect the 380 kV submarine cables across the Strait of Messina. Acting during the construction phase, the company deployed its specialist seabed preparation and mattress‑laying equipment to stabilise and shield sections of the cable system where additional mechanical protection was required. This scope formed part of the wider offshore installation and protection campaign for the Messina II HVAC link between Sicily and mainland Italy.
