Record-Breaking Submarine Cable Installation at 2150m
material based on High Modulus Synthetic Fibers, shapes the new generation of cable technology. The use of an innovative armoring solution that in water can be 50% lighter than steel, combined with the state-of-the-art Leonardo da Vinci cable-laying vessel, will enable the installation and maintenance of Terna’s Tyrrhenian Link at a water depth of more than 2,000m, the deepest ever reached with a power cable.The success of the sea trials is the result of many laboratory tests and proves once more the solidity of Prysmian innovations. The same light weight armor technology had been in fact used in
Prysmian Performs Record Deep HVDC Subsea Cable Installation
armored cable has been designed with a composite material based on High Modulus Synthetic Fibres.The use of an innovative armoring solution that in water can be 50% lighter than steel, combined with the Leonardo da Vinci cable laying vessel (CLV), will enable the installation and maintenance of Terna’s Tyrrhenian Link at a water depth of more than 2,000 metres, the deepest ever reached with a power cable.The success of the sea trials is the result of many laboratory tests and proves once more the solidity of Prysmian innovations.The same light weight armor technology had been in fact used
NextGeo Concludes Tyrrhenian Link's East Section Survey for Prysmian
support service provider Next Geosolutions (NextGeo) has completed all the pre-installation survey tasks for the Tyrrhenian Link East branch on behalf of Prysmian.The works entailed extensive marine detailed geophysical, geotechnical, UXO, archaeological and environmental survey activities along the Terna’s submarine power line connecting the landing points in Sicily and in Campania with two HVDC cables, approximately 485 kilometres long each.Additional survey tasks have been executed in the nearshore sections of the corridor, including boreholes, HDD survey, topography and geoelectrical investigatio
Italy's TSO Tests Subsea Drone for Marine Geophysical Surveys
Italian transmission system operator (TSO) Terna has launched an autonomous underwater vehicle (AUV) Gavia as part of a collaborative project with U.S. start-up Terradepth.Terna and Terradepth are working together on the Odisseo project, whose aim is to advance the technologies and methods for marine geophysical surveys related to the development of important subsea infrastructure and its security.As part of the Odisseo project, the first offshore tests were conducted near the port of Casamicciola Terme, on the island of Ischia.During geophysical surveying of the seabed, Terna’s technicians were

Eni-led Group to Build Wave Power Stations
Italian oil group Eni is joining forces with shipbuilder Fincantieri, power grid group Terna and state lender Cassa Depositi e Prestiti (CDP) to develop wave power stations.The agreement, which follows the understanding signed last 19 April, will launch the first phase of a joint project to convert the Inertial Sea Wave Energy Converter (ISWEC) pilot project, an innovative system that transforms energy generated by waves into electricity, into an industrial scale power station, making its application and use immediately available.The partnership agreement will focus on two phases: during the first
Submarine Power Cable Links in the Venetian Lagoon
Venetian Lagoon After having built the previous high voltage submarine cable link connecting Venice, Murano and Mestre, Energy and telecom cable systems company Prysmian Group has now secured a project for submarine power cable links in the Venetian Lagoon. Prysmian announced that Terna Rete Italia has confirmed a series of additional work that was originally included as an option to be added to the Venetian Lagoon submarine power cable links project, a contract awarded to the group last year following a European bid. The new work scope is worth approximately €20 million
