Fulton Hogan engaged AWMA to supply an isolating penstock for the pipeline inlet of Tasmanian Irrigation’s Arthur Supply Project as part of the Midland Water Scheme.
The penstock shall be manufactured from marine grade aluminium and engineered to withstand approximately 7.5m of on seating head pressure.
The penstock will be designed to allow operation via a handwheel or AWMA’s Portable Actuator.
In addition to the penstock, AWMA will design and manufacture a set of segmented stoplogs to provide secondary isolation to the inlet chamber for facilitation of maintenance activities. Each stoplog segment is designed to be approximately 2.0m wide, 1.5m high and fabricated from marine grade aluminium.
Insertion and removal shall be facilitated by AWMA’s self-engaging stoplog lifting frame which has been designed to effectively eliminate the OH&S risks associated with such infrastructure.
The Midlands Water Scheme is a large irrigation project designed to support the expansion of agriculture in the Tasmanian midlands through the provision of high surety water. This project is due for completion in December 2013.
