Contractor 4Recycling has been working alongside dredging specialist Land and Water Services to find a solution to treat and reuse more than 32,000 tonnes of PCB-contaminated sediment.
Land and Water Services' used their machine, a Hitachi ZX280, on an eight-piece Ravestein pontoon. To achieve the highest accuracy on this job and to reduce material overage, the machine was equipped with Prolec’s flagship dredging control system pcX-Pro. The system utilised marine grade AS7 angle sensors and a combination of one RTK GNSS antenna with Prolec’s unique CANBUS heading compass.
PcX-Pro's ability to define avoidance zones combined with highly accurate positioning meant the containment of sediment was much easier compared with other solutions available. In addition to this, a shadow mode system was also installed in the supervisor's office. Using this remote system, full access to all views and a clear image of job progress were available. Again showing the ability of Prolec to tailor our systems according to customers’ requirements.
