Operational Planning and Power Management System for Offshore Platform With Wind Energy Supply – Impacts on CO₂ Reduction and Power Quality

This paper considers the operation of offshore oil and gas platform energy systems with energy supply from wind turbines to reduce CO₂ emissions. The study is conducted through simulations of a case that reflects a “typical” oil and gas platform on the Norwegian Continental Shelf, with energy demand for gas lift and gas export compressors, separator train, oil export pump, water injection pumps, accommodation and utilities.

The study case with wind energy is compared to a base case with only gas turbines, and both cases have been implemented and analysed in multiple simulation tools. Results have been compared and used to assess the impact of wind integration on CO₂ emissions, gas turbine fuel usage and wear and tear, power system frequency stability and other key indicators.

The results are consistent between the modelling tools, and indicate a potential for CO₂ emission reduction of 20–25 % for this case with a wind energy share of 26 %. There is some variation depending on the amount of reserve power required and the rules for when to start up and shut down gas turbine generators.
