Prolec system used for harbour decontamination 

Belgian dredging contractor Dredging International (via joint venture EDI), was first supplied a pcX-3D system for a harbour decontamination project in Castletownbere, Ireland. The company has subsequently gone on to be the largest user of the highly advanced pcX-3D.

The entire €9.5 million project involved the dredging of approximately 95,000 metres³ of sediment and the blasting of 15,000 metres³ of rock. PcX-3D was deployed because the dredging works were complicated by the presence of the now banned anti-fouling agent Tributyltin (TBT).

Over 34,000 metres³ of sediment was contaminated by TBT from depths of 750mm to 2,000mm. PcX-30 was installed on a long reach CAT375 fitted with an EGO bucket and when combined with RTK GPS was capable of achieving theoretical accuracies of better than 50mm.


The pcX-3D machine guidance system uses precision sensors to monitor the position of the bucket or blade to
give precise digging control.
