Control cabinet

As part of the Nordstream pipeline project, Netherlocks has provided an electro-mechanical control cabinet in combination with an interlocking system for the pigging process. A custom, explosion-proof and climate controlled control cabinet was designed and manufactured in close co-operation with Siemens AG.

A complex, dangerous process, pigging can be made safer using mechanical interlocks. However, Netherlocks says a standard interlocking system typically does not include monitoring, is not linked to the various pressure levels, and would not include the facility for remote operation of Motor Operated Valves.

The Netherlocks control cabinet combines all these aspects into one unit: remote MOV operation controls are included, and correct pressure and position of MOVs are conditional requirements to release the keys for each stage of the process.
