Aurora was contracted by Archer to carry out a full set of power system studies for an upgrade of the Topaz offshore platform with a new modular drilling unit (MDU).

Aurora’s scope included modelling the entire network using DIgSILENT Powerfactory from the base data provided by the Client. ONce the model was created, Aurora then carried out simulations for loadflow, fault level, motor starting, harmonics, transient and dynamic stability and then finally carrying out a protection coordination study for the whole installation.
