WSDOT Symposium: Breakthrough in Mitigating Marine Pile Driving Noise

February 2, 2015

ORGANIZERS

Washington State Department of Transportation
University of Washington, Mechanical Engineering Department
Marine Construction Technologies, PBC

LOCATION

University of Washington, Husky Union Building, Seattle, WA

SUMMARY

A symposium and panel discussion about a new double wall pile designed to improve noise attenuation, focusing on impressive results from recent full scale testing in Puget Sound.  This innovation was developed and tested with support from WSDOT, the Federal Highway Administration, the Port of Tacoma, and several leading engineering and environmental consulting firms.

Panel Discussion

 

"Reinhall Piles provide a much needed and environmentally beneficial innovation in the arena of marine construction. This technology can significantly reduce the noise mitigation effort and setup time, and is far more protective."
Michael Spillane, PE, President Herrera Environmental Associates

Hear the difference

Recorded from hydrophone deployed at 10m during subscale testing of 8" steel piles in Seattle, Washington in 2013.

You are hearing 4 strikes of a standard pile followed by 4 strikes of a Reinhall Pile™. Notice the difference.
