The Transmission System Operator of the Spanish Electricity System, Red Electrica de Espana (REE), awarded Prysmian a contract for the second circuit of the interconnection between the Balearic Islands of Mallorca and Ibiza.
The project involves the design, supply and installation of a turn-key High Voltage Alternating Current (HVAC) cable system designed to transmit power of 118 MVA for the interconnection between the two islands that will enable integration of Ibiza in the Peninsular network system by ways of the existing 'Romulo' (Iberian Peninsula-Mallorca) cable system.
The submarine cable route length is approximately 117 km and is divided in two (2) sections: the shallow water section, 20-21 km on each side and the deep water section. The submarine power cable was installed at a maximum water depth of 790m.
Prysmian awarded ASDG with a subcontract for the laying of the cable at the shallow waters of Ibiza and Mallorca and the protection of the shallow and deep water sections in Ibiza and Mallorca. ASDG's scope of work included also the loading of the cable sections from Prysmian Factory in Italy, as well as an as buried-survey of the areas.
