    Recently full-flow penetrometers (a cylindrical T-bar or spherical ball) have emerged as an alternative to the conventional cone penetration test (CPT). The T-bar was originally developed for strength determination in the centrifuge (Stewart & Randolph 1991) and its success in the lab led to its use in the field (Stewart & Randolph 1994). The potential of the T-bar for use offshore was shown by Randolph et al. (1998). The ball penetrometer was later developed to reduce the likelihood of non-symmetrical loading on the T-bar which would result in bending of the penetrometer shaft (Watson et al. 1998).
