This subproject develops generic methods, models and digital tools for analysis and optimisation of offshore energy systems with renewable energy supply, to enable cost- effective, reliable and stable design and operations of hybrid offshore energy systems with low or zero CO2 emissions. The focus is on power systems, but heat supply is also considered. A key output will be digital solutions that leverage computing power, digital ecosystems, and the huge amount of data among operators.

Main objective

Consider the integration of low-emission technologies into offshore energy systems and develop methods, models and tools to support design and analysis.

  • Optimal design and operation of hybrid energy systems with renewable energy integration
  • Models and methods for detailed analyses of electrical stability of proposed solutions
  • Integrated energy tools and data-driven methods supporting industry digitalisation

Results 2020

Created an open specification and energy and power system models of an oil and gas reference platform ("LEOGO") for research purposes.

  • Added operational uncertainty to the HyOpt investment planning model.
  • Improved the OffshoreOilandGasEnergySystemOperation (Oogeso) tool.
  • Estimated impact on CO2 emissions and other key indicators for a platform partially supplied with wind energy, using a power management simulator (PPSim) and the Oogeso tool.
  • Investigated inertial and primary frequency support by an energy storage system for an oil and gas platform with wind power supply (submitted for journal publication).
  • Preliminary integration of topside, reservoir and energy system models and analysis of water injection scenarios and impact on CO2 emissions
