Repair & maintenance - Import export

The safe and efficient construction and operation of gas transmission systems calls for complex decisions; there are a number of prerequisites that must be met. This applies to many areas such as material selection, component design and sizing, well-founded assessments of the condition of pipelines and facilities based on various test procedures, the determination of the repair and maintenance work required as well as quality assurance for materials, procedures and personnel. We offer a comprehensive service portfolio in this area, based on the experience and know-how gained from the operation of our pipeline network and the technical infrastructure available for this purpose.

Maintenance and repair work on the natural gas network is generally carried out with the pipeline being gas-free, so the relevant pipe sections are isolated by installing valve assemblies and the gas in the isolated section is vented to atmosphere. By using our mobile compressors – individually or in highly efficient parallel operation – the network operator can transfer the gas from the isolated pipe section to another part of the system so it does not have to be vented to atmosphere. Connection points for the mobile compressors are available e.g. in the area of the main line valves or can generally be retrofitted. It makes economic sense to transfer the gas to another as this guarantees responsible handling of this primary energy source and makes a substantial contribution to protecting the environment.
