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.
Function
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.
