Due to the large scale of facilities in the power, oil and gas industries, small improvements to operational efficiency can result in substantial productivity increases and cost reductions.

Vortices being shed by a set of 6 oil rig risers of different sizes.

Using advanced modelling techniques, such as CFD and dispersion modelling, Synergetics engineers have assisted clients with a range of operations including:

  • heat exchanger modelling and optimisation;
  • wind loading on oil rig and flare tower arrangements;
  • improved ventilation in natural gas compressor stations;
  • modelling and assessment of site location and configuration for novel wind and hydro turbines;
  • energy assessments to minimise consumption and to identify opportunities for green energy generation, such as photovoltaic solar panels;
  • optimisation and simulated performance assessment of thermal energy storage systems;
  • optimisation of combustion processes to reduce burner fuel consumption;
  • feasibility assessment of a proposed cogeneration facility; and
  • dispersion modelling from power generation and refining plumes for licencing and OHS purposes.
