Produced Water Beneficial Use Program – Multidiscipline Engineering Design

October 2023

Project Scope

In 2023 Biggs Design Engineering (BIGGS) completed two facility and packaged equipment skid designs for a coal seam gas (CSG) produced water beneficial use program that achieved an environmentally positive outcome. The project achieved a successful outcome by blending the output from a water treatment facility with produced water to provide a blend suitable for the end user. As one of our first multi-discipline projects, we are very proud to have helped one of Australia’s largest energy providers achieve a successful project outcome.

BIGGS completed the full multi-discipline engineering design of two facilities and packaged equipment skids including process engineering, electrical design and instrument selection, facility layout, piping system design in DN150 to DN300 CL150 piping, stress/flexibility analysis to manage the above ground piping to buried pipeline interface, and structural design of the skids. We also provided project management from scope definition through to procurement support of instruments and equipment, and skid fabrication. In partnership with trusted service providers, BIGGS was able to successfully deliver this project from a Qld based team.

The services provided by BIGGS on this project included:

Full multidiscipline engineering design and project management of the design team
Workshop facilitation for multidiscipline plant layout and 3D model reviews.
Process engineering design including hydraulic calculations, flow control valve sizing, and P&IDs.
Mechanical and piping drawings including plot plans, skid general arrangement drawings, Plant 3D model, and piping isometrics.
Development of Plant 3D piping specifications on the client’s behalf.
Piping system design and stress analysis in Caesar II to ASME B31.3.

Structural skid design to AS4100.
Electrical and instrumentation design including:
- Selection and procurement support for flow meters, pressure transmitters, and flow control valves.
- Drawings and calculations including cable block diagrams, termination diagrams, loop diagrams, panel drawings, power and heat calculations, and cable sizing.
- Hazardous area drawings and calculations.
- Automation scope of work for the control system designer.
