Germany – Radio stations – Ausrüstung des Neckars mit AIS-Landinfrastruktur

The subject of the tender is the supply, installation and operational handover of land-based infrastructures for the inland AIS system at a total of 18 locations along the federal waterway Neckar. The measure serves to expand the existing inland AIS service, which already comprises 120 stations nationwide. The new stations will be erected at existing lock and technical buildings. At most locations, joint accommodation with existing Nautical Information Radio (NIF) facilities will take place. The scope of services is divided into supply, installation and testing services. The contractor will provide the complete supply, the professional installation and the operational handover of all components for the land-based inland AIS infrastructure at 18 locations along the Neckar. Supply services: The supply service essentially includes the provision of telescopic antenna masts including all necessary fastening elements. Furthermore, the contractor will supply powerful VHF omnidirectional antennas for AIS and NIF radio as well as high-precision GNSS antennas including the associated spare antennas. For signal transmission, low-loss coaxial antenna and adapter cables are provided, whereby special Cellflex lines are used for longer cable routes. The accommodation of the technology takes place in new 19-inch equipment racks to be delivered, which are designed as combo-colocation racks or in standard version depending on the location. Finally, the supply includes the active system components such as AIS base stations, network switches and IP power switches as well as all installation material from power to data lines. Installation services: As part of the installation services, the specialist personnel will erect the masts and antennas while strictly adhering to all distance and height specifications. The craftsmen will erect the necessary wall and roof penetrations and seal them with standard-compliant fire barriers and weatherproof seals. All cable routes will be properly laid and permanently labelled. At the affected locations, the contractor will dismantle the old cabinets, integrate the existing NIF radio components into the new cabinets and put them back into operation. As part of the dismantling work, the contractor will take over the professional, environmentally sound and complete disposal of all dismantled old cabinets as well as the no longer needed old materials. The new 19-inch cabinets will be fully assembled, properly earthed in accordance with EMV and professionally connected to the on-site power supply and existing UPS systems. Testing and additional services: Before the installation of the antenna systems, the contractor must submit a qualified structural safety certificate for each location. After the installation, a metrological quality inspection of the antenna systems will be carried out to prove the required limit values of the signal quality. A qualified electrical expert will also carry out the legally prescribed DGUV Regulation 3 initial inspection and document it with test protocols and plates. For all height work to be done, the contractor will independently provide the necessary scissor lifts. The contract concludes with the handover of a complete, digital project documentation on five USB sticks within two weeks after successful commissioning.
