“…Setup has been postulated to derive predominantly from an increase in shaft resistance (Komurka et al, 2003). According to Chow et al (1998), relaxation is more likely to aŠect base resistance than shaft resistance.…”

“…Pile setup for a pile installed in sand resulting from an increase of shaft resistance was ascribed to arching mechanisms by Robinsky and Morison (1964) and Chow et al (1998). Arching in the case of axially loaded piles means that load is not transferred along the shaft only through simple shear (Loukidis and Salgado, 2007) Salgado and Prezzi, 2006) can be used for calculating the increases in horizontal stress, provided that the dilation and soil stiŠness can be quantied.…”

“…Many researchers (Camp III and Parmar, 1999;Bullock, 1999;Long et al, 1999;Svinkin et al, 1994) suggested t0 ranges from 0.01 to 2 days. The parameter A is reported to be in the range of 0.2 to 0.8 (Chow et al, 1998;Axelsson, 1998;Bullock, 1999). There are other empirical equations available; they should be used with extreme care, as they are based only on site-speciˆc conditions and have questionable predictive ability.…”

“…For this reason, Axelsson (2002) and Chow et al (1997Chow et al ( , 1998 attribute pile setup mostly to Stage 3 (aging) and to a lesser extent to Stage 2. A portion of the setup may result from creep-induced breakdown of the driving-induced arching``structures'', resulting in increased shaft friction.…”

“…A portion of the setup may result from creep-induced breakdown of the driving-induced arching``structures'', resulting in increased shaft friction. The build-up of shaft resistance can continue for at least several months (Axelsson, 2002;Chow et al, 1998 Chow et al (1998), the marked setup in sand is due to weakening of the arching mechanisms surrounding the pile shaft by creep/relaxation, which leads to an increase of radial eŠective stress. According to Chow et al (1998), capacity reductions with time are limited to 1) short-term relaxation due to the recovery of pore pressures following dilation during driving, 2) relaxation for piles founded on rock, 3) relaxation for piles in closely-spaced pile groups.…”

Pile foundations for offshore structures can be installed in different ways, with this article focusing on two main pile types: (i) driven; and (ii) drilled and grouted. An overview of simplified mechanics‐based concepts for issues affecting analysis of pile installation is provided. For driven piles, the concepts considered include soil resistance to driving, dynamic soil models, and pile damage. For drilled and grouted piles, attention is focused on methods to avoid hole collapse and hydraulic fracture. With these concepts in mind, a designer can minimize the potential for costly remedial activities that may be required during pile installation if the above issues have not been adequately addressed.

This article summarizes design methods for pile foundations subjected to axial and lateral loading. It addresses the main factors that need to be considered in a basis of design, focusing on driven steel pipe piles, which are almost universally used in offshore practice. The response of less frequently used piles grouted into stronger sediments, such as calcarenite and other weak rock, is also considered. Modern design approaches based on data from cone penetration testing are outlined. For lateral response, the main focus is on load transfer methods. Reference is also made to elastic solutions that can provide a useful approach for operational loading, particularly for large diameter monopiles such as are used in the offshore wind industry. Just as for axial loading, the potential use of cone penetration data as the basis for deriving lateral load transfer curves is also discussed. Underlying principles of the effects of cyclic loading are presented. The article concludes with brief comments on scour and seismic design, two other considerations for the design of offshore piles.
