SUPPORT EQUIPMENT

Survey boats are equipped with the latest positioning, sounding, and data collection equipment and software. Data on seabed conditions is gathered by our survey boats and transferred to guidance systems aboard the dredge fleet. This information provides dredge operators real-time representations of seabed contours relative to the dredge’s position.
