Viktor Lenac repairs, converts and refits ships at Kostrena, on the approach to Rijeka in Croatia. It is a member of the Italian Palumbo Group. The site runs to 670,000 square metres including water, with 11,000 square metres of workshops and warehouses and a separate offshore construction area of 130,000 square metres served by a 300-metre heavy-lift loading pier. Sixteen cranes lift up to 100 tonnes: seven ashore, seven on the docks, one floating and one bridge crane. No newbuilding is done here.
Three graving docks are in service, taking vessels up to Suezmax size and rated for 160,000, 60,000 and 20,000 deadweight tonnes respectively. Dock 11, the largest of the three, took its first ship on 4 September 2024 after an extended renovation. Four ultra-high-pressure water systems are in use.
The business runs in five lines: ship repair, conversions, offshore, long reach support and specialised services. Long reach support means sending teams out to vessels away from the yard, which together with the offshore line explains the unusually broad trade coverage the yard maintains in house.
The reference list leans towards offshore and specialist units rather than merchant tonnage: the semi-submersible drilling rig Scarabeo 4, the floating production unit Helix Producer I, the cable ships Cable Enterprise and C/S Giulio Verne, the heavy-lift crane vessel SHCV Sampson, the K3000, and the vessels Atlantic Navigator and Seminole. Naval work for the United States is a distinct strand: the yard completed the five-year Extended Service Life Programme on USS Mount Whitney (LCC-20) on time and on budget while absorbing an additional 35 per cent of work arising from discoveries during the docking, and its cooperation with the US Navy's Military Sealift Command is long standing. A passenger ship overhaul and refit contract was signed in February 2022.
