Prolec awarded contract to remove 32,000 tonnes of sediment as part of marina restoration project

Land and Water Services (LAWS) use Prolec’s latest dredging monitoring system pcX-Pro for Cornwall’s marina redevelopment scheme. 

Contractor 4Recycling has been working alongside dredging specialist Land and Water Services to come up with a solution to treat and reuse more than 32,000 tonnes of PCB-contaminated sediment. 

LAWS machine, a Hitachi ZX280, was used on an eight piece Ravestein pontoon. To achieve the highest accuracy on this job and not to remove more material than needed, the machine was equipped with Prolec's latest dredging monitoring system pcX-Pro. The system uses marine grade AS7 angle sensors and a combination of one RTK GNSS antenna with Prolec's unique CANBUS heading compass.

In addition, a shadow mode system has been set in place in the supervisor's office. Using this remote system, full access to all views and a clear image of progress is given, demonstrating Prolec's ability to tailor systems according to customer’s specifications.
