The Petroleum port is located approximately 0.5 M from the entrance to the Rijeka basin. The port is protected by a 235-m long breakwater on the south side. The breakwater was damaged in several places. The length of the northern wharf is 186 m (Berth 1). The wharf in the eastern part of the port is 80 m long (Berth 2). The port was used for the transhipment of petroleum products from the Mlaka refinery, which is no longer in operation.
