Project description
swb Services GmbH is planning to build two river water heat pump systems in the “Vordere Neustadt” district of Bremen, each with a thermal capacity of 2 × 5 MWth and 2 × 2 MWth. The aim is to use environmental heat from a branch of the Weser River or the Weser itself, through heat pump technology and feed it into the municipal district heating network. INP was ordered with the project-specific engineering including the review and refinement of existing urban development preliminary plans and convert them into plans that are suitable for approval and tendering.
INP was ordered to verify and supplement the existing preliminary investigations. This included the planning of the intake and discharge structures, the sizing of the heat pumps, the routing of the media supply lines, the connection to the district heating network, and coordination with the approval authorities and specialist planners. In addition, the tender for the plants was to be structured and prepared. The collaboration took place in close cooperation with the swb project management team.
