Introduction

As a pioneer in air-insulated and gas-insulated switchgear, Siemens has 25 years of know-how in the development of switchgear and switching devices. Customers can take full advantage of this technology. Since the power demand for processes in the oil & gas industry is increasing, Siemens Energy is covering this high rated-current and short-circuits demand with air-insulated (up to 38 kV) and gas-insulated medium-voltage (MV) switchgear (up to 40.5 kV).

The MV gas-insulated switchgear at a glance:

Compact and modular design
Reduced footprint
Maintenance-free
Independent of pollution and humidity
Motor load for the oil & gas processes: In excess of 80% of the project power

The MV air-insulated switchgear at a glance:

Withdrawable design
Fused contactor feeder panels (only half the width of a circuit-breaker panel)

Both the air-insulated and the gas-insulated switchgear have an extremely good safety record with high reliability and availability.

The Siemens low-voltage (LV) switchboard has a modular design with high combination flexibility. Adaptations for new performance demands during operation can be carried out easily by exchanging the withdrawable units or changing the compartments. The LV switchboard is available in a fixed-mounted, plug-in and fully withdrawable design and as a Motor Control Centre (MCC).

Global capabilities for switchgear and switchboard

Siemens has global engineering and manufacturing capabilities for our medium-voltage and low-voltage switchgear and switchboard and holds important approvals and certifications for onshore and offshore applications in oil and gas.

SIPLINK, power transmission and power distribution

In this section you will also find information on SIPLINK and its application on drill ships to create fault-tolerant power supply systems for the thrusters to avoid drift-off of the ship. This keeps stability of the power plant high and in the event of a black-out brings power back to the thrusters within approximately 17 seconds. Additionally, there is a general overview of the Siemens portfolio in power transmission and power distribution products, systems and solutions in our Power Engineering Guide.

City Network Ulm “SIPLINK for Peak Load Exchange”, Germany

A new system for the city power districts was required to permit connection of different energy suppliers and networks, Siemens selected its SIPLINK (Siemens Multifunctional Power Link) system. Siemens’ scope of supply:

2 MVA power-link between two networks for power flow control
Improvement of voltage quality by reactive power regulation
Exchange of active power between both networks in case of peak-load
2 MVA in multi parallel service

Transocean – new enterprise class, Korea

A fail-safe energy supply for the consumer and a decrease in the number of running generators in low load mode were required. Siemens E D MV 3 developed a solution with inverters, which can provide energy from two different sources. Siemens’ scope of supply:
