... frequency deviations from three offshore wind turbines in the Walney offshore wind farm 2. Review of the API p-y formulation The API p-y formulation for piles in sand (API, 2011), are based upon the recommendations from O Neill and Murchison (1983) and Reese et al. (1974). The lateral soil resistance (p...

.... The cyclic driving stresses ap- plied to the piles can also impact on the fatigue life of the steel. Factors which influence driveability in- clude the makeup of the hammer driving system, pile dimensions and soil resistance. Methods to estimate the soil resistance to driving that are commonly used...

... Abstract The disturbance of the seabed that comes from natural processes, like iceberg keels, presents a potential issue for the installation of pipelines. The zone of soil disturbed by the iceberg and the soil resistance force to the object movement is of interest to the offshore geotechnical...

... the application of drained or undrained conditions to be estimated for pipelines in clay/slit soils. The main purpose of the paper is to present a method for estimating the axial soil resistance using a relative roughness parameter, as well as making recommendations on the displacements necessary to mobilize peak...
