Asso.subsea transported and installed four distinct 110 kV cable systems, with the northern part connecting the landing sites Mali Bok – Merag and Osor bay on the islands of Krk, Cres, and Lošinj, and the southern part linking Prapatna – Medvidbad and Travna – Slatina between the islands of Brač, Hvar, and Korčula.
The project was carried out in collaboration with contractor Končar on behalf of the Croatian transmission system operator (TSO) HOPS, and the activities were performed using the Atalanti cable laying vessel (CLV).

The replacement of old cables along these routes with 3x 630 mm2 submarine cables, totaling approximately 30,500 meters, was also executed.
The company noted that onshore pull-in activities needed preparation works before pull-in activities to all sites, which together with pull-in operation posed significant challenges, with two operations necessitating HDD pipes measuring around 120 and 60 meters in length, respectively.
Additionally, due to steep slopes with turns at various sites, Asso.subsea said it had designed and manufactured specific rollers. Gradients of up to 40% were encountered at locations such as Prapatna and Slatina.
Atalanti and pull-in teams onshore executed three consecutive landing activities.
