ABSTRACT: Driven steel tubular piles are most commonly used for offshore structures and are becoming popular onshore as well. Typically, offshore piles are required to support large loads and are bigger in diameter, wall thickness, length, use high performance steel and require high-energy impact hammers to install. Pile drivability predictions are critical for selecting the appropriate hammer(s) to successfully install the pile to the required depth. The pile drivability assessment is carried out using a combination of a wave equation analysis and the soil resistance to driving (SRD). However, the methods to estimate SRD and the drivability analysis vary between offshore and onshore. This paper presents some selected experiences for both onshore and offshore locations for estimating SRD and carrying out drivability analysis. The procedures for SRD estimations for offshore include use of CPT data and friction fatigue concept during installation. The similarities and dissimilarities between the onshore and offshore situations are demonstrated for SRD predictions and drivability analysis.
