Construction of two highly complex feed systems for biomethane with a total of three main compressors, in a joint venture

Scope of Services:

Overall coordination, construction, installation, commissioning and maintenance of two fully modular plant systems, including analysis, measurement and control technology, entire associated pipeline construction work; packaging of the main compressors

Technical Details:

• Fully modular plants consisting of 11 sub-units in modern module and container construction technique, unit weights up to 90 t
• Pressure levels: PN 16, PN 84; flow rate: 3 x 1,400 Nm³/h biomethane

Particularities:

Plants for supplying up to three network sections of different pressure levels with dynamic load changes; construction process was significantly more difficult through upstream third-party plants: extensive coordination and planning effort, delay in commissioning => plant preservation necessary

Technical leadership in the construction of several gas pressure control and metering systems for the natural gas receiving station Lubmin 2

Range of Services in Detail:

• Planning, monitoring and coordination of all work during the project
• Manufacturing and assembling services as well as EMSR work
• Commissioning
