On 31.05.2022 by the company GEOmar d.o.o. a hydrographic survey of the actual condition was carried out on the route of the submarine part of the construction - submarine three-core oil 110kv cable on the section from KS Surbova (island Krk) to KS Stojan (island Rab), and on 01.06. on the section from KS Tiha (Kraljevica) to KS Šilo (Krk island).

The measurement was carried out for the purposes of designing a new submarine cable, detecting the existing submarine power cable and entering the subject cable into the official maritime charts and publications of the Croatian Hydrographic Institute. As part of the project, a geodetic survey of the land part of the route is also carried out.
