Safe transport of oil and gas

Pipelines

Reliable operation of pipe heating

Pipelines

Pipelines are used to transport oil and gas across long distances. Pipe heating systems and other heating systems are also required in the process. These are monitored by type “B” Bender fault current systems. Any faults are reported immediately before a system shutdown becomes necessary.

Compressors and condenser stations

Secure compression with RCMS

Compressors and condenser stations Secure compres

In a compressor or condenser station, a compressor compresses the natural gas in order to compensate for pressure losses. The natural gas is stored at high pressure, and the pressure in the pipeline falls because of flow losses. The compressor is driven by a drive machine at up to 30 MW. These drive machines can be either gas turbines or gearless electric motors. For electric motors, frequency converters are required, which need to be monitored for their insulation levels or existing leak currents.

Pump stations

Pumps with inverters - safety at all frequencies

Pump stations

In order to cover relatively large distances, there are pump stations to pump the oil or gas. Since the pressure in the raw material to be transported is reduced due to flow losses, the aim of the pump stations is to increase pressure again. The pump is powered by gearless electric motors. This means frequency converters are required, and these need to be monitored for their insulation level or any fault current present.

Tank stores

Electrical safety for strategic reserves

Tank stores

Tank stores are stores in which fuels can be stored. Materials in the tank stores are often pumped around using large pumps powered by gearless electric motors. Frequency converters are normally used in the process to monitor insulation levels or existing leakage currents.

Tank ships

Transporting oil and gas safely over the seven seas

Tank ship

A tanker transports liquids or gaseous materials such as crude oil, oil as a finished product, fuel or liquid gas. Tankers have pumps for unloading and pumping around the load on board. These pumps are powered by gearless electric motors for which frequency converters are required to monitor for insulation levels or existing fault currents. One of the key components of shipping engineering is the main machine with its auxiliary generators, kettle systems, auxiliary diesel and the generators for power generation and loading pumps. The main distribution board on-board the tankers are generally designed as unearthed systems which are monitored with ISOMETER®s and fault locators.
