High-voltage (HV) substations (>52 kV) provide the necessary electrical energy e.g. for LNG plants or for refineries. Since processes in the oil & gas industry are becoming more and more complex and power-demanding it is nowadays often mandatory to use HV substations. Siemens Energy top quality gas-insulated switchgear covers the highest safety standards for operating personnel and provides extremely high reliability. It also holds important approvals from the oil & gas industry. The space-saving modular design of the switchgear allows tailor-made customer solutions and requires a minimum of maintenance.

Highly efficient large onshore power plants can provide the electrical energy to feed offshore clusters of production platforms with more cost savings and lower losses than the decentralized operating gen-sets on each offshore platform. On top of this, the centralized power generation onshore would markedly reduce CO2 and NOX emissions. Siemens offers solutions to bridge these distances and to provide the connection between the power plant and the offshore cluster by means of
