Global cleanup

Shell is cleaning up its image by improving the quality of produced water from its gas platforms. As part of a global scheme, the Gannet platform in the North Sea has installed a water quality improvement system using triple offset rotary process valves from Tyco Valves and Controls. The platform is the first in the Central Field to install an induced gas flotation system which claims to reduce overboard emissions by 50%. The bi-directional, zero leakage operation of the triple offset valve makes is applicable for primary isolation duties on the system’s inlet/outlet and by-pass pipelines.
