The project provides for an unprotected pier on the outer side of the rubble-mound breakwater and the extension of the existing quay wall on the inner side of the breakwater. The area is intended for high-speed lines (catamarans) for passengers arriving at or departing from Split Airport, shifting road traffic to the sea and thereby contributing to environmental protection, particularly by reducing greenhouse gas emissions. Kaštela Basin D – Resnik consists of a land and a sea section. The land section includes the access plateau and road along the entire breakwater up to the operational quay, as well as part of the breakwater with a final layer of protective rock armour extending from the operational quay. The current quay structure consists of an operational quay approximately 40 metres long on the inner side of the breakwater, which is about 250 metres long in total and protects the berthing area from waves generated by the bora and sirocco, the most frequent winds in the area. The planned works include an unprotected pier on the outer side of the breakwater with dredging to a depth of -5.30 metres and the extension of the existing quay wall on the inner side of the breakwater. The new pier will provide a seasonal landing for two high-speed vessels (catamarans) up to 40 metres long. The pier will be 53 metres long and six metres wide. Its body is generally formed of dolphins and "bridges", i.e. prefabricated reinforced concrete beams monolithically joined with a reinforced concrete slab. At the root of the pier, underwater and above-water walls (1.50 metres wide) will be added on both sides to widen the pier and provide a turning area for fire engines. The works also include the pier on the outer side of the breakwater (perpendicular to the existing quay, as a summer berth). The seabed will be deepened over a length of about 170 m (measured perpendicular to the shore) to provide manoeuvring space for vessels at the outer berth. The existing quay wall will be extended by 52.27 metres, retaining the existing quay width of nine metres, providing a berth for one vessel up to 40 metres long. As the existing water main lacks capacity for the port's future needs, it will be decommissioned and a new water network will be built along a new route with a new connection to the municipal water main. Four utility cabinets supplying ships with water and electricity are planned. The project is worth EUR 2.5 million (including VAT) and is planned to be co-financed from EU funds.
