After replacing DC UPS systems on a number of Statoils platforms (Gullfaks A, B and C, Statfjord B and C and Draupner, to mention a few), ComPower have gained solid experience in this field.

The new UPS systems that were delivered on this project are both modern and well developed systems that utilize alarm- and rectifier modules from Eltek Valere with more than a 96% power ratio.

In addition to this, ComPower also supplied their newly developed discharge test unit for regular maintenance testing of the system. This unit returns the battery power to the mains supply rather than dissipating it in a load, saving a lot of work and energy.

The systems were delivered according to specifications from Statoil, and according to the standards in NORSOK T-100
