The execution of a jetty using Symmetrix system to install piles into the bedrock level was a big challange for the contracting consortium. To overcome these challenges, Symmetrix large diameter DTH system, worked as a perfect innovative solution.
"Symmetrix requires only one barge, whereas we need two for conventional piling. We achieve four piles in a 12 h-day, compared to two using conventional piling techniques."

Challenge
To drill beneath the waves to install the bridge piles.
Products
The piling system comprised a Birminghammer, BHD 40 rotation head, a QL200S DTH Hammer, a Symmetrix system with reverse circulation drilling string and three Atlas Copco XRHS compressors.
Benefits
Using Symmetrix Large Diameter system in Leixoes harbour enabled:
• Fast drilling through unconsolidated, fissured ground down into the hardest bedrock
• No changes of bit to drill the socket below the casing
• Saving time enabling four piles to be installed per a 12 hours shift compared to two piles using conventional methods
• Drilling a metre in twelve minutes instead of sixty minutes when using conventional methods
• One barge whereas in conventional piling two barges are needed
Conclusion
Drilling with Symmetrix saves you time, lowers your cost and leaves a job that you can be proud of!
