A cone penetration test (CPT) approach to cable plough performance prediction based upon centrifuge model testing
نویسندگان
چکیده
Cable ploughing is an important technique for burying and protecting offshore cables. The ability to predict the required tow force plough performance essential allow vessel selection project programming. Existing models require calibration against full-scale field testing determine empirical parameters, a requirement that may hinder their use. In this study factors controlling resistance were investigated using series of dry saturated 1/50th scale model cable tests in sand geotechnical centrifuge at 50g range target trench depths, relative densities, velocities. An improved predicting separates out key components allows prediction without use field-derived coefficients presented. It demonstrated parameters can be easily determined from situ cone penetration (CPTs), allowing it used where site investigation techniques more limited compared onshore locations. validated tests, demonstrating correctly both static (dry) rate effect (saturated) forces.
