As part of a general overhaul, Siemens Energy has equipped two drilling platforms owned by Transocean of Houston, Texas, the largest offshore drilling company in the world, with a reliable, high availability power supply. The new system based on the direct current network link Siplink replaces the former power supply for the drilling platform drive units.

The Siemens solution not only increases the reliability and availability of the drive units but also offers savings of up to a third of the fuel costs for the diesel generators accompanied by a reduction in CO2 emissions. Generator maintenance costs can also be cut because the generators can run at a considerably more effective operating point controlled via a fail-safe energy bus.
