Pile Driving Predictions for Pile Driving from Floating Installation Vessels
Offshore Technology ConferenceAbstract A common approach for offshore windfarms is the installation of the turbine on top of a steel monopile that is driven into the seabed with a vibratory hammer. The use of that hammer type has distinct advantages over that of an impact hammer.

Improved Pile Installation Predictions for Monopiles
2019As the world transitions toward more sustainable energy sources, there is an increased interest in renewables, with offshore wind well placed to provide significant grid-scale input. Historically, a key limitation has been the cost, with the first offshore wind farms in Europe costing $175 to $250 per megawatt-hour (MWh).

Pipe pile installation effects in soft clay
Proceedings of the Institution of Civil Engineers - Geotechnical Engineering, 2006The shortage of field measurements to examine existing predictive methods for pipe piles in clay prompted an experimental programme in Shanghai, China, in which displacements and stresses were measured in the vicinity of two pipe piles during their installation in a soft lightly overconsolidated clay.

Pile Driving Measurements on the Heather Platform Installation
Proceedings of SPE European Petroleum Conference, 1978Abstract The first leg piles of the Heather Platform were instrumented using strain transducers and accelerometers that were attached to the pile just below its top. The signals were processed in real time providing for a hammer blow a printed output of hammer energy in the pile, maximum pile top force and other ...

Vibratory Pile Driving Hammers for Pile Installations and Soil Improvement Projects
Offshore Technology Conference, 1987ABSTRACT The capability of hydraulic vibratory pile driving hammers and other techniques using the principles of vibration have so far been underestimated by offshore foundation engineers. In many installation projects vibratory hammers should be considered as a real alternative, in other projects as a complementary

Design of sheet pile installation by vibration
Geotechnical & Geological Engineering, 2004In The Netherlands 70% of the steel sheet piles are installed with vibrators. This is because vibrators have a high production rate and therefore a low installation cost. This method only works for soft peat and clay layers and saturated sand layers which are not densely compacted. During pile installation several problems might occur.

Visco-elastic consolidation subsequent to pile installation
Computers and Geotechnics, 2000Driven piles normally generate excess pore pressures in the surrounding soil. Dissipation of the pore pressures following driving is predicted currently by available elastic theory. However, viscosity is pronounced for many soft clays, therefore, its eAect should be suitably accounted for.
