The Teledyne PDS software suite applied to construction and dredge

Teledyne PDS for construction and dredge is used to monitor the progress of your project. Inside the Teledyne PDS suite there are a number of specialized out of the box solutions for a variety of specific applications. But you also have the possibility to combine different applications and customize Teledyne PDS to the exact solution you need. We also use our 30 years of industry experience to build new applications together with customers to address their special needs.

The Teledyne PDS suite uses the same basic user interface and logic across all applications, which means once you are familiar with the suite it will be much faster to add new applications to your setup.

Here you can take a closer look at our out of the box applications for Dredge and Construction

Various sensors and information – one solution – one overview

Teledyne PDS dredge systems support hydraulic excavators, wire cranes, bucket dredgers, underwater ploughs, trailing suction hopper dredgers (TSHD),  cutter suction dredgers, jet dredgers, water injection dredgers and any other dredge vessel. Depending on the type of dredger the necessary sensors are interfaced and combined with information of your project such as the surveyed area, the design, charts,  it provides the complete overview. The modular setup of Teledyne PDS makes it easy to extend the standard dredge solution with additional features to carry out more complex projects. As an example you could combine digging and diking or placement of material in one dredging system, or integrate a multibeam with a dredge guidance system such as a TSHD or a cutter dredger.  Also a multibeam on a Pan/Tilt unit is a solution to monitor the area combined with an excavator or wirecrane.

Another example within construction would be to integrate an underwater crawler with a multibeam system and USBL for positioning of deep water dredging.

Let’s look at some real life examples…

Seabed reinforcement of the Little Belt Railway Bridge in Denmark

In the spring of 2014, Peter Madsen Rederi began work on the Little Belt Railway Bridge in Middelfart, Denmark. Due to settlement and scour, the bridge’s geotechnical stability had to be improved, which was done by carefully placing 169,000m3 of rocks within tight tolerances at a water depth of 40 meters.

During the work at the bridge, daily multibeam echosounder surveys were performed, which allowed Peter Madsen to continually evaluate the work carried out, and thus update and make new deployment files in their Teledyne PDS system. This way they were each morning able to provide feedback to the crane operators about the previous work and the current state of progress.

Caisson Placement and dredge solutions for the Mose project in Venice.

To protect Venice from contentious flooding the city is constructing the Mose Storm surge barrier. Teledyne PDS* was among other technologies used to help dredge parts of the area and guide the placement of the multi ton caissons in 25 meter of water.
