Hamburg. For efficient and smooth operation of the port of Hamburg all infrastructure must be kept continuously available, steadily rising requirements demand regular port expansion. For this purpose, extensive maintenance measures and innovative construction projects are necessary which are planned and implemented by the Hamburg Port Authority.
Since 2019 ONP experts have supported the Hamburg Port Authority AöR (HPA) in the planning of various infrastructure projects in the Hamburg Harbor.

ONP supports HPA Projects listed in the following
The project is characterized by the challenging boundary conditions with Hamburg's deepest berth and Germany's largest transshipment site for coal and iron ore.
ONP supported the setting up of a monitoring system for automated real-time monitoring of the deformation behavior of the existing combined sheetpile wall.
Since 2020, ONP has been supporting the HPA in the coordination of planning and the technical matters of the HOAI service phases 1 to 4, i.e. from the basic investigation to the approval planning.
The City of Hamburg pursues the goal of sustainably improving air quality in the city and reducing CO2 emissions. In compliance with the defined clean-air target of the environmental planning for 2025 the use of shore-side power supply for seagoing ships during berthing in the Port of Hamburg is of great importance.
In the process of achieving the set goals, shore-side power supply facilities for container and cruise vessels are planned to be built and operated. The Hamburg Port Authority (HPA) was assigned by the City of Hamburg with planning and construction of this shore-side power supply facilities.
ONP is supporting the HPA project team during the planning and design process until approval planning, the tendering and contracting phase until construction and implementation management.
As a lift bridge the 1934 built Rethe-bridge was a significant element of the infrastructure in the port of Hamburg. The bridge managed by the Hamburg Port Authority (HPA) and crosses the Rethe at the mouth of the Reiherstieg. An economic maintenance of the bridge was no longer possible, so new construction of the road and track connection was indispensable. As a substitute for the old lift bridge the new Rethe-Doppelklappbrücke (double folding bridge) was built directly west, which was commissioned in 2016 for car traffic and in 2017 for railway transport. As from mid of September 2018 the old lift bridge was demolished, leaving the foundations in place so far.
Due to the close vicinity of the two bridge structures and the fact that the new bridge is already in operation, extensive planning and monitoring measures are required in the course of the reconstruction of the substructures of the old bridge and the interactions on the new double folding bridge.
In form of a subproject management ONP performs the following services: Coordination of planning for the dismantling of the foundations of the old bridge, additional investigations on alternative demolition methodologies, development of a task and interface matrix to consider the interactions for the removal of the old bridge with the operation of the new double folding bridge as well as the coordination of the implementation. In addition, ONP coordinates the procurement procedure and supervises the required continuous construction monitoring.
When the Köhlbrandbrücke was inaugurated in 1974, no one would have ever thought that the traffic would be as high as it is today, and thus the increase in strains the bridge would be succumbed to. When the first container ships came onto the scene, the transport of heavy goods, in particular, experienced a drastic boom. Today, around 38,000 vehicles cross over the bridge daily, and despite the extensive refurbishment in 2016, the ability of the bridge to remain in operation will end in 2030. A restriction on overtaking for trucks has already been in place since 2012. In January 2019, HPA took additional measures for protecting the bridge permanently – as a result, trucks in the area of the river bridge now have to maintain a distance of 50 metres from one another. This distance rule will be in force until the necessary reinforcements of the steel bridge have been made.
On 13 February 2020, Federal Transport Minister Andreas Scheuer and Hamburg's First Mayor Dr. Peter Tschentscher signed a declaration of intent in Berlin, which states, among other things, that the federal government will contribute financially to a new Köhlbrand crossing and that this will be upgraded to a federal road for this purpose. On the basis of various studies prepared by HPA, the order for general planning of a drilled tunnel as a substitute construction for the bridge was commissioned by HPA in October 2019.
In June 2019 ONP was awarded to support HPA during the forthcoming project phases. In addition to the tasks of the overall planning coordination for the project in the HOAI Performance Phases 1 - 4, ONP supports the various tunneling subprojects as well as associated construction logistics and brings in tunneling and technical expertise into the project. Furthermore ONP is responsible for the planning coordination in the area of civil engineering and bridge construction (new and reconstruction). In addition ONP supports the HPA project management during procurement and tendering processes and contributes to specific technical issues and risk management.
