Island harbor Prerow

The "Inselhafen Prerow" project is one of the most important hydraulic engineering projects on the German Baltic coast. Commissioned by the Rostock State Office for Agriculture and the Environment, a completely new replacement port for the Darßer Ort emergency port was built between 2022 and 2025. This was built on the seaward side off Prerow - around 650 meters off the coastline - as a horseshoe-shaped island port. The overall project has a contract volume of 34.4 million euros and was carried out by several construction companies in a joint venture, including Ed. Züblin AG with a 28% share of the work.

The construction of the new island port is a key infrastructural measure for maritime safety in the Baltic Sea region. As the existing Darßer Ort port of refuge was becoming increasingly silted up and its functionality could no longer be guaranteed in the long term, a sustainable replacement was created with the construction. The core of the project was the construction of the longest pier in the Baltic Sea - 720 meters long after the extension - which ensures the connection of the offshore port to the onshore transport network. At its end, the new island harbor was created, which covers a wide range of uses: from rescue operations and fishing to tourist shipping and pleasure craft seeking protection.

The extensive technical work included massive hydraulic engineering works. A total of 800 tons of structural steel, 400 tons of sheet piling and 700 tons of reinforcing steel were used. The use of 140,000 tons of fill material and 52,000 tons of armourstone formed the artificial island structure and protected the facility from erosive loads. In addition, 240 driven piles, 73 steel pipes and dolphins and a 3,024 m² concrete slab were constructed. Around 40,000 m³ of sand and sediment were moved as part of the dredging work. Corrosion protection measures on 16,400 m² coated the steel components and ensured their durability in the maritime environment.

Once completed, the island harbor itself will have a total of 44 berths. These include a permanent berth for the DGzRS rescue cruiser with additional space for a dinghy or a damaged ship, a berth for the DLRG and eight berths for local fishermen - two for fishing boats and six for smaller boats. The offer is supplemented by 33 berths for pleasure craft seeking protection, three berths for local businesses and an emergency berth for larger vessels up to around 30 meters in length.

A modern operations and functional building with a roof terrace, which serves both port logistics and rescue and monitoring functions, was built at the same time. A new passenger ship jetty was built in the northern area of the pier, which complements the tourist use and further strengthens the region around Prerow.

The new construction of the Prerow island port has created a state-of-the-art, multifunctional and safety-relevant port structure. It significantly improves the region's maritime infrastructure, strengthens coastal protection and offers long-term safe conditions for sea rescue, fishing, trade and water sports.
