Geothermal Engineering Support

Geothermal facilities can require highly specific engineering support across modelling, field supervision, electrical documentation, and protection systems. DAG supported multiple independent geothermal assignments, providing focused engineering capability across several disciplines and work scopes.

Case Study 03

Specialist engineering support across multiple geothermal assignments

DAG Service Specialist Engineering Support – Geothermal
Duration February 2018 – April 2020

The Challenge

The requirements were not limited to one discipline or one assignment. The work called for specialist engineering inputs ranging from pipe-network and hydraulic modelling to site supervision, as-built documentation, and electrical protection-upgrade drawings.

DAG’s Solution

DAG provided targeted engineering support for each assignment, matching the required technical capability to the specific work scope. This allowed different project needs to be addressed through focused engineering inputs rather than a one-size-fits-all delivery model.

Scope of Engineering Support

  • Pipe-system modelling and network de-bottlenecking studies.
  • Development of engineering information and hydraulic models.
  • On-site supervision for geothermal project activities.
  • Preparation of electrical as-built drawings for operating facilities.
  • AC schematic, DC elementary CAD, and cable-schedule drawings for protection-system upgrades.

Result / Value Delivered

Across the independent assignments, DAG demonstrated the ability to provide specialist engineering support from front-end modelling through field supervision and technical documentation. The portfolio reflects the breadth of DAG’s geothermal experience and its capacity to respond to different technical requirements across operating facilities.
