Overview

The rapid growth in offshore wind energy requires the use of effective and efficient foundation solutions for both fixed bottom and floating structures. Monopile and conventional hammer-driven tubular piles on jacket structures may be reaching their current design limits, and with growing concern over the noise caused by their installation, alternative foundation solutions need to be considered.

Screw piles have long been used onshore and if their design can be upscaled appropriately, the effectively silent installation and high axial loading capacities are just two examples of the benefits which screw piles could provide the offshore wind sector.

This presentation will cover experimental work using the geotechnical centrifuge at the University of Dundee to investigate the feasibility of using large screw piles for offshore wind energy foundations. Limitations of current installation and axial load design methods are discussed along with the proposal of new and improved methods.

Further insight into how the changing of installation parameters can reduce installation loading requirements and enhance tensile capacity are also presented using evidence from additional centrifuge and numerical modelling tests.

Buffet and networking from 17:30, meeting starts at 18:00.
