Bendeela Pipeline Control Structure

February 8, 2017 by

The Bendeela Pipeline Control Structure is an integral part of the Shoalhaven water supply and power generation scheme.

The control structure isolates the Bendeela Pipeline from water contained in the Bendeela Pondage, protecting the Bendeela Power/Pumping Station from flood events and allowing internal pipeline inspections and maintenance works.

AWMA were engaged to design, manufacture, supply, install and commission:
• 1 off 4300mm wide x 8000mm high marine grade aluminium segmented stoplogs (4 of 2m segments) including a 200mm venting valve inserted into 20m deep guides
• 1 off marine grade aluminium, stopboard selfengaging lifting frame
• 1 off marine grade aluminium storage rack

AWMA’s Stoplogs and ancillary equipment (lifting frame and storage racks) provide double isolation for the control structure.

When isolating the Bendeela Pipeline during maintenance, four of the stoplogs are fitted one on top of the other, in the existing concrete chambers.

The top sealing stoplog segments provide complete sealing against a water depth of 16m and inserted in 20m deep guides Venting of the internal chamber to prevent a vacuum was provided via flexible pipe connected to the surface.
