ABSTRACT
The application of bored pile foundations in offshore (marine) conditions poses unique challenges that engineers and contractors should be aware of with regard to their design and installation. The offshore (marine) environment is typically associated with the need for relatively long length, large diameter, foundation elements that must extend through significant water depth and poor, low strength soils to a competent bearing stratum. These conditions can affect the design of bored piles by offering limited shaft resistance and requiring deep embedment in order to develop pile fixity and resistance to lateral loads. High axial capacity demand usually requires these elements to significantly penetrate into dense soil and rock. Carefully planned site investigations are essential to obtain the requisite subsurface information needed for design and installation considerations.
