Conductor Installation Services Completes Pile-Driving Ops

Conductor Installation Services Ltd (CIS), an Acteon company, announced that it has completed a pile-driving operation in conjunction with construction of a major gas production and processing development in Australasia.  Working in the jungle, CIS performed a series of pile-driving operations in order to form the foundations of three new bridges, a jetty and two wharves.  The CIS hammer services crew of four commenced the first phase of the pile-driving operation, which was associated with construction of two wharves on a river. With one of its 90 kJ hydraulic hammers located offshore on a barge in depths to eight meters (26 feet) and a second positioned onshore, the CIS crew operated the two hammers simultaneously.  CIS drove 12 x 48-inch abutment piles and 116 x 18-inch ground support piles to ensure that the new wharves would be built on solid foundations. Following completion of the wharf pile-driving phase, CIS went on to drive 30 x 18-inch and 18 x 48-inch bridge support piles as part of the construction of three bridges. CIS drove the bridge support piles with the aid of surveyors and the hydraulic hammer on the piling crane.  All piles were driven to their specified target depths.
