Instrumenting offshore piles with strain gauges and accelerometers to monitor the driving performance of hammer, dynamic stresses, pile integrity, and pile/ soil response to measure mobilized compressive capacity has been one of SGES’s core competencies.

A pre-installation drivability study for various driving conditions (i.e., SRD’s- soil resistance to driving) will be performed (using GRLWEAP software) to choose the optimal hammer size necessary to drive the pile safely to the intended target penetrations. The force and velocity signatures captured by the PDA are further analyzed using signal matching software, CAPWAP, to confirm the mobilized compressive capacity (together with resistance distribution along shaft and toe) and arrive at dynamic soil constants.

A team of qualified, experienced, and PDCA/PDI-certified geotechnical engineers/technicians with advanced to expert ratings will be mobilized on every project. The rich experience gained over several offshore pile driving monitoring projects of various oil companies enables us to make good field measurements and engineering judgments/ interpretations required for pile acceptance. The same test method can also be used to monitor pre-cast driven piles for hammer/driving system performance, driving stresses, and soil resistance to driving for the construction of on-land projects.
