If you want to do your best to protect our salmon or other marine life while driving pile, why not choose a vibratory hammer to drive that next underwater pile? With such an emphasis on the environment these days, a recent definitive study commissioned last year by Caltrans on the issue of the effects of pile driving on marine life lists vibrating pile as the best pile driving method to protect Sea Life. In section 2.5 titled: Common Underwater Sound Reduction Measures, vibration of pile is listed as a preferred method to reduce sound in underwater pile driving compared to other pile driving methods. Evidence suggests it is the safest method for wildlife and the only method not to reach the dangerous 183db level. Attached is the entire report which is a must read for all you contractors driving underwater pile. There is also a ton of material about how to best handle underwater noise issues when driving any kind of pile with most types of hammers.

Steve Gough, Managing Director for APE International Sales, helps introduce the “Fat Man 220” the largest diesel hammer in the world to a contractor’s party held in Shanghai, China. The D220 (Fat Man) operated flawlessly while all the major Chinese pile contractors cheered. This was a historical moment for Steve Gough and for APE and SEMW. The D220 was sold to China Oil. Steve kissed the Fat Man D220 to give it good luck on its first job. The D220 has a twenty-two metric ton ram and is designed to replace large troublesome hydraulic hammers. The D220’s smaller brother, the D180 is currently driving piles for the new San Francisco Bay Bridge and another D180 just finished the piles for the Pitt River Bridge in Vancouver BC- Two of the largest pile jobs in the world. Thanks to Mr. Wong and Mr. Gong for innovations that have changed the world of pile driving forever.

APE Tandem 400 King Kong Installs Super Large Diameter Piles For Largest Bridge Ever Built by Mankind
On August 9, 2004 , MBEC ( CHINA ZHONG-TIE MAJOR BRIDGE ENGINEERING GROUP CO.,LTD) drove down the first steel casing into the Yangtzu River with APE Tandem Model 400 Vibro . The steel casing is 2.8 meter in diameter, 20 mm in thickness and 42 meters in length. The first part of the casing is 27 meter long. After driving down the first part, they welded up the second part which is 15 meter. The casing was driven 35 meter into the soil. MBEC will drive 40 casings ea for two piers of Su-Tong Bridge.
