As part of a major state highway upgrade, a 300mm gas pipeline needed to be laid through sandy soils that were prone to a high water table and liquefaction. This raised the issue of the buoyancy of the pipeline under saturated conditions, and the need to ensure minimal movement to maintain the structural integrity of the system. A permanent buoyancy control solution was required that could be installed quickly and efficiently to keep pace with the project time line.
In order to achieve good loads the S8 anchors were driven 5m deep, through sand into a layer of gravel, and then locked in the gravel layer. Each anchor could then be proof tested immediately to give assurance to the designers that the required loads were being met. The whole installation process was streamlined by the use of specialist Platipus Installation Tools, and training from the Cirtex site support team.
The products used provided the following benefits to the project:
PlatipusBuoyancy Control Anchoring Systems have a number of attachments and tensioning devices to connect to pipes or tank being anchored.
