BRUCE ANCHOR® TRACKER

The Bruce Anchor Tracker is mounted on a drag embedment anchor and has a pivoting probe which automatically aligns with the embedment trajectory of the anchor and measures drag distance and depth of embedment. The system incorporates a microcomputer which reads the inclination of the probe from an internal inclinometer at fixed distance intervals along the anchor trajectory. The distance intervals at which measurements are taken are set by a soil turbine mounted on the rear of the probe body. As the anchor moves forward incident soil rotates the turbine to operate an internal switch which makes the microcomputer read the inclinometer outputs once per revolution. Knowing the distance interval per revolution allows a full embedment trajectory to be constructed.

The Bruce Anchor Tracker enables rapid assessment of a proposed mooring site using an anchor handling vessel. By recording multiple radial trajectories, a three dimensional display can be constructed to identify the presence and extent of stratification at a given site, enabling the question, "Is this site anchorable?" to be answered from detailed trajectories previously unattainable. The Bruce Anchor Tracker offers cost-effective site appraisal which may eliminate the need for geotechnical investigation.

With the introduction of the Bruce Anchor Tracker, it also becomes feasible to monitor directly each anchor in a mooring pattern on a continuing basis to measure any movement due to storm loading.
