Prolec's pcX system grows dredging business for Moray Council

Moray Council expands its dredging capabilities with Prolec's advanced guidance system, pcX-Pro

When Moray Council wanted to expand its dredging capabilities and promise a higher degree of accuracy to its customers while also maintaining all six Moray Council harbours, it approached James Fisher Prolec (Prolec) to assist with the advanced guidance system, pcX-Pro built in to its dredging vessel.

Now, thanks to Prolec's sophisticated system and expert training, the Moray team in Scotland is working closely with Forth Ports Ltd to develop annual dredging campaigns in a number of harbours in the Firth of Forth. Work has already been carried out in Newhaven to facilitate access for bringing passengers ashore from cruise ships, and in Methil to allow safe access for cargo vessels.

The pcX-Pro guidance system allows the user to see detailed digital terrain models and designs of the environment around them. On water-based projects this allows the operator to ensure they dredge the sea or riverbed to the correct depth – a process called ‘on grade’ - without actually seeing it.

pcX-Pro provides a digital calculation of exactly how much material has been removed from the sea or riverbed to ensure the operator consistently dredges to the correct depth.

Joe Lawson, project development lead at Prolec explains:

‘We were able to help the team from Moray Council make optimal use of pcX-Pro so they could really showcase its features to win this contract.’

The extra training has enabled them to expand their dredging services from small ports and sandbanks to much bigger contracts and to confidently assure Forth Ports that they could achieve the accuracies necessary for the job, and so build their reputation as an excellent dredging team.

Joe adds:

‘Dredging jobs are prone to over- and under-dredging where too much or too little silt and debris is removed. This can have serious implications in ports where vessels can become grounded if levels are not low enough, but over-dredging can affect water levels and can even destabilise foundations of walls and peers.’

Prolec is working hard with existing customers, such as Moray Council, to help expand the potential of their pcX and PME systems. In fact, the team will be upgrading the Moray Council pcX system to include the full Confident Construction suite of technology services on a trial basis which will automatically set height, reach and slew limits with minimal operator involvement and allow the dredger to override the operator and stop the bucket from dredging once it hits the desired depth.
