Think outside the box (culvert): How creativity sells more precast
Highlighting three important projects that are creating opportunities for producers of box sections, simply by utilizing an existing product in new ways and with new requirements.
Demolition of a former mine site - Luke Egan and David Wood
Liberty Industrial was engaged by Glencore to complete the demolition of a former coal preparation plant on a redundant mine site in Teralba NSW. While the mine was non-operational and formerly underground, many of the mine systems, plant pass-in and permitting requirements were based on on the site being an operational underground mine. Both Liberty Industrial and Glencore worked together during the planning phase to ensure that both parties understood the work, the design-related aspects and aspects of the Glencore systems that were not appropriate for this type of work. The teams worked together to develop a risk-based approach that satisfied the Glencore internal systems while maintaining efficient execution processes.
Ship dry docking
Dry docking involves docking a vessel to expose its entire wetted area for inspection, maintenance, and repair work. It is required by classification societies on a periodic basis to conduct docking surveys and maintain the vessel's class. The key areas inspected during dry docking include the ship's hull plating, sea suctions, propeller, rudder, and anchor system. Careful consideration of the vessel's stability is also important when positioning it on keel blocks in the dry dock and refloating it.
Horse Casing Slipstream
1) Original wells at Leland Horse field produced casing and tubing together but production decreased when casings were shut in due to friction losses in the tubing.
2) A casing slipstreaming system was developed to intermittently produce the casing to allow extra gas to flow while maintaining critical rate in the tubing to prevent liquids loading.
3) The system uses automation including SCADA to control a choke and monitor tubing flow from remote sites. It increased production by 5 to 25 million cubic feet per day with a payback period of less than 13 days. Casing slipstreaming is now standard for new wells in the area.
