Older information construction phases of the gas compressor station

April 2023: Pressure test successfully carried out; integration of the valve group into the Nordschwarzwald pipeline completed

April 2023: Pressure test successfully carried out; integration of the valve group into the Nordschwarzwald pipeline completed

In March, a pressure test of the fittings group and fuel gas pipeline was successfully carried out.
The construction of the new valve group as a link between the Nordschwarzwald pipeline and the gas compressor station is almost complete.

The connection of the fittings group to the existing Nordschwarzwald gas pipeline (NOS) of terranets bw was successfully completed at the beginning of April.The connecting pipeline from the fittings group to the compressor station has also already been laid. The connection is scheduled for April 2023.

In the past few weeks, the roof work on the operations building and the energy centre was completed. The interior work is progressing; floors, doors and stairs are being installed and painting work is being carried out.

In the coming weeks, the interior work on the operations and workshop building and the energy centre will continue at full speed. The pipe construction of the compressor station should essentially be completed by summer.

February 2023: Interior works in the buildings start, pipe construction for integrating into the Nordschwarzwald pipeline progresses

After a short winter break, construction works for the gas compressor station in Rheinstetten were resumed at the beginning of the year. The facade works on the machine hall progress. The roof work on the operations building and the energy centre is expected to be finished in March, at the same time interior works begin. In February, the last pipe material for the pipe construction was produced and will now be delivered step by step to the construction site.

Welding work has now started on site to construct the connection line to the Nordschwarzwald pipeline (NOS) as well as for the fuel gas pipeline. Welding of the fittings group has almost been completed. Integration of the gas compressor station into the NOS is expected to occur in April. At the same time, reforestation of woodland areas in Rheinstetten begins with the planting of oak trees and robust shrubs in February. These measures were defined as ecological compensation measures for the construction of the station.

December 2022: Delivery of the electric compressor, integration into the Nordschwarzwald pipeline is prepared, first compensation measures have begun

With completion of the four compressor halls, they are now ready for installing the compressor units. In December, two of the three gas compressors as well as the electric compressor were already delivered. The turbines for the compressor units have already been delivered and the last compressor will be delivered in January 2023. Parallel to this, construction works on the operations building and energy centre are progressing: the first floor of the operations building has been completed, structural works for the energy centre will be finished in January 2023.

The civil works for the fittings group as well as the connection lines to the Nordschwarzwald pipeline (NOS) have also been completed. The pipes are ready for the pipe construction, which will begin at the beginning of next year. Foundations for the piping of the compressor station were also poured. Simultaneously, the first ecological compensation measures for the construction of the gas compressor station were initiated.

November 2022: Compressor halls, filter systems and gas coolers are erected, integration into the Nordschwarzwald pipeline is prepared

All four halls are erected where the compressor units will be installed in the next months. Construction of the operations building, in which both the repair shop and the offices for terranets bw employees will be located, has made great progress. This means that the landfill of the site to reduce the incline to the Panzer street could begin.

In addition, integration of the gas compressor station into the existing Nordschwarzwald gas pipeline (NOS) is prepared. The civil works of the fittings group required for this will be completed by the end of the year. Parallel to this, connection lines to the NOS are being built. The filtersystems through which the gas is cleaned prior to the compression process have already been assembled and the gas coolers that will cool down the gas to transport temperature after compression have also been installed in the meantime.

September 2022: Construction site opening day, delivery of turbine for the first compressor unit

On 24 September, as part of the Baden-Württemberg Energy Transition Days, terranets bw enabled all interested parties to gain an insight into the construction of the gas compressor station. At different stations, visitors could learn about the construction, function and importance of the gas compressor station for the energy transition.

In addition , experts were available to answer questions and exchange information on the project at information boards as well as at vantage points over the construction site. At the end of September, theturbine was delivered that forms part of the first compressor unit.

August 2022: Mayor of the City of Rheinstetten visits construction site

In the middle of August, Sebastian Schrempp, Mayor of the City of Rheinstetten, visited the construction site and together with Managing Director Katrin Flinspach, the Technical Project Leader Nils Höger and the Commercial Project Leader Susanne Kurschat, was able to gain an impression of the construction progress on site.

In August, the gas cooler is installed as planned and in the meantime, great progress has also been made on the interior works in the compressor halls. Installation of the first compressor unit begins in autumn and by the end of the year, the remaining three compressor units will be installed. With the erection of the operations building and the energy centre, structural works for all buildings are also to be completed by the end of the year.

July 2022: Three compressor stations are built; inlet pipe is being prepared

Structural building work of three of the four planned compressor halls has been completed. The fourth compressor hall is expected to be finished at the end of the year. Finishing works in the halls have also begun in the meantime along with preparations for installing the machines.

The compressor units will be delivered and assembled by autumn 2022. Additionally, work has started on the station piping together with preparations for fitting the gas cooler in August 2022.

May 2022:Construction of the machine hall has begun

May 2022: Building construction of the machine hall has begun

Now that foundation work for the machine hall and the operation building have been completed, structural work for the machine hall has begun. After fitting the ground slab, the columns for the hall have been erected. After that the wall elements, delivered as prefabricated parts, will be installed.

Commercial Project Manager, Susanne Kurschat, and Technical Project Manager, Nils Höger, inform themselves weekly about the progress of the construction measures with an on-site inspection.

January 2022: the setting up of the construction site completed, preparation of the foundations

Construction works for the new gas compressor station in Rheinstetten are progressing. Recently, setting up of the construction site was completed. This means all storage, handling and traffic areas are prepared. Equipment, machines and containers for the workers as well as for weather-sensitive building materials are also ready. terranets bw´s technical project manager, Nils Höger, who is regularly on site, also has a permanent working place on the construction site. In these weeks, foundations for the planned buildings such as the machine hall, the energy centre and the administration building are being prepared.

For this purpose, the previously braided rebars are filled with concrete. The surrounding formwork ensures that the concrete can harden without any negative external impact.
In the next step, the ground slabs are also made of reinforced concrete and will later support the prefabricated walls. And what is indispensable in all this: both 25-metre-high construction cranes used for construction site logistics.
