Dave Singleton will describe company's role in rescuing Chilean miners
Dave Singleton, president of Layne Christensen Co.’s Water Resource Div., will describe the dramatic drilling operation that rescued 33 trapped Chilean miners last year as part of the June 13 Opening General Session of the American Water Works Assn.’s (AWWA) Annual Conference and Exposition (ACE11) in Washington, D.C.
The session, which begins at 8:30 a.m. at the Walter E. Washington Convention Center, also will feature a presentation from Yoshihiko Misono, executive director of the Japan Water Works Assn., on the earthquake and tsunami recovery efforts in Japan. Singleton, who helped organize the rescue from Layne Christensen’s Western Region offices, will relate how Layne Christensen Co. repurposed a Schramm T130 tophead drill to create a 26-in.-diameter hole through which the miners emerged. The scheme, known worldwide as “Plan B,” helped cut two months off the estimates for a rescue and safely reunited all the miners with their families.
