Abstract

To simulate the prototype installation behaviour of screw piles at realistic confining stress lev-els, a new installation and loading rig, consisting of two independently-controlled servo-motor drive systems was developed to allow screw pile models to be installed and axially load-tested inflight in one operation at 50 g. This system was developed around the Scalable Actuator Control System architecture (SACS) recently installed on the Dundee centrifuge, based around a National Instruments compactRIO controller with modu-larly scale-able servo drive interfaces. 1:50 scale model screw piles were manufactured from mild steel with 10 mm diameter cores with 25 mm diameter flanges welded on, representing a new generation of larger screw pile proposed for offshore marine renewable applications. These were installed up to 200 mm depth in dry dense sand to demonstrate the performance and capabilities of the new actuator. This paper details the design philosophy and operation of the servo motor actuation system for inflight screw pile installatio
