Hvar - Korcula

Asso.subsea completed the installation phase of HOPS’ 110 kV submarine cable replacement project in Croatia, including the southern section that links Prapatna–Medvidbad and Travna–Slatina between the islands of Brač, Hvar and Korčula. Working for contractor Končar on behalf of transmission system operator HOPS, the company transported and installed four 110 kV cable systems totaling about 30 km and approximately 30,500 m of new 630 mm² submarine cables, replacing the old links; HOPS separately noted that the Brač–Hvar–Korčula submarine cable replacement was realised in the same campaign.

As part of the completion of the 110 kV submarine cable project serving, among others, the Travna–Slatina route between Hvar and Korčula, Asso.subsea finished all cable landfall operations at the island landing sites, including those on Brač, Hvar and Korčula. The contractor reports that onshore pull‑in works and three consecutive landing activities were successfully executed despite steep coastal gradients, using preparatory works, HDD pipes at two sites, and specially designed rollers to bring the new cables ashore and secure the shore crossings.

On 22 January 2024, Hrvatski operator prijenosnog sustava (HOPS) commenced works to replace the 110 kV submarine cables between Brač–Hvar and Hvar–Korčula, including associated onshore cable sections and the revitalisation of cable houses. The construction campaign, running until mid-June 2024, replaces ageing oil-insulated cables with more environmentally friendly technology to improve long-term security of electricity supply and support renewable energy integration for the islands, including Korčula.

On 22 January 2024, Croatian transmission system operator HOPS commenced works to replace the existing 110 kV submarine cable between the islands of Hvar and Korčula, as part of a project also covering the Brač–Hvar link. The activities include laying and jointing new environmentally friendlier 110 kV submarine cables, replacing the old oil‑insulated cables, and associated works on land sections and cable houses, with the installation campaign planned to continue until mid‑June 2024 to enhance security of electricity supply and support renewable integration on the islands.
