RINA, in JV with the Tunisian subsidiary Comete Engineering, has been awarded a public tender for the marine feasibility study for the 600MW Italy-Tunisia Interconnection issued by ELMED ÉTUDES SÀRL, a joint venture between Terna and Société Tunisienne de l’Électricité et du Gaz (STEG), the two companies which, respectively, manage the Italian and Tunisian electricity transmission grids.

The Italy-Tunisia electric Interconnection is an important project for two-way electricity transfer between the two countries. Stretching over 200km with land and sub-sea sections to a depth of 800m, the ‘invisible’ cable will add resilience to power supply.

The submarine survey project, which started in April 2021, and will run for one year, will identify two possible landfalls at either end of the interconnection, determining which are the best options in terms of geological and environmental aspect. It will also establish possible routes for the underwater section identifying and evaluating constraints and obstacles.

Initial landfall and route studies will be followed by topographic, nearshore and offshore field surveys.
