Asset management for underground gas storage

Functions | Benefits | Range of Services

Securing the feed in and discharge capacity, reducing operational and maintenance costs, guaranteeing the reliability of geomechanics: these are the core aims of operations in underground gas storage.

You achieve these goals by using the solution zedas®asset for gas storage management. With zedas®asset you have all the cornerstones for efficient technical operations management:

  • Information about the plant's currently available feed in and discharge capacities
  • Reporting for authority engineering
  • Continuous diagnosis and forecast of plants' load case
  • Calculation of storage content for cavern and pore storage (SIB)
  • Diagnosis of overground plants (OGP, GDRA)
  • Further processing of process data to analyse condition and logging in technical machinery report
  • Forecast of energy demand using the energy data acquisition and analysis module (EAAS)
  • Planning and tracking of maintenance measures
  • Mobile workforce management

Technical asset management using zedas®asset is geared towards operators and service companies in the field of underground storage (UGS), gas storage, LNG storage, gas compressors and gas drying.




For maintenance

  • Monitoring the load and condition of plants and components
    (asset performance monitoring)
  • Forecasting wear and tear development of selected components as well as specific lifecycle costs (LCC, TCO) as part of asset lifecycle management (ALM)
  • Control of inspections and maintenance as well as the documentation and processing of results
  • Mobile recording and processing of malfunctions
  • Support of different maintenance strategies (condition-based maintenance, risk-based maintenance)
  • Analysis of operational data to determine the causes of faults and for benchmarking (balanced score card) in malfunction and damage analysis
  • Full lifecycle report for plants and components as the basis for asset management decisions (capex/opex)

For technical operations management

  • Assistance system to automatically instruct operator and maintenance personnel
  • Reporting on compliance with operational parameters when running the plant and components
  • Determination of storage content and storage reserves for cavern and pore storage
  • Determination and use of capacity reserves for operations
  • Selection of flow direction to guarantee feed in/discharge capacity taking into account the plant's load case
  • Monitoring and logging of geomechanical parameters for authority engineering
  • Determination of energy efficiency
  • Energy demand forecasts for energy management

For asset management

  • Automated reporting and functional cockpits (capex / opex)
  • Support of continuous improvement process (CIP) as part of plant asset management (PAM)


Benefits for the gas storage operations

Securing and improving plant performance:

  • Prevention of unplanned downtimes
  • Utilisation of capacity reserves
  • Optimisation of operation (operating point)
  • Guaranteeing plant availability and reliability

Reduction in operational costs:

  • Flexibility of maintenance according to operational requirements
  • Planning of maintenance measures depending on load

Shortening of planned plant outages:

  • use of preparation time in case of deterioration in condition
  • bundling and coordinating of maintenance measures (mechanical, electrical, hydraulic)


Optimisation of business processes:

  • Support of fast measurable decision-making processes
  • Transparency of operations management and authority engineering
  • Development and use of a basis of knowledge to improve plant operation and maintenance


Using zedas®asset you guarantee the asset performance management of plants and components, assured plant availability and increased plant reliability.
