Profiler software is used on board dredgers and barges. It is used to monitor, calculate and display the positions of all moving machinery on the vessel. This can include dragheads, the boom, stick and bucket of a backhoe, or other underwater machinery.Main screen showing a CSD working in head-up mode on a background map.
Main screen on a trailing suction hopper (in this case the Queen of Penta Ocean) dredger showing the plan view and a text display. The text display can be configured to show whatever information is most important to the user. The plan views will usually include the vessel (with moving parts), reference maps (DXF etc.), and surface models showing the design surface and pre-dredge survey. The models are used to display currernt and required depth at the current position, and to display real-times profiles at the digging or dumping location.
Second screen on a custom-built barge used in 'geotube' placing operations for reclamation in Singapore. Profiler supports up to 4 individually customisable display screens. This barge was positioned with RTK (providing accurate height instead of using tide) which also gave heading. Pitch and roll sensors completed the barge positioning. Sensors (optical shaft encoders) on the winches, coupled with laser distance measuring, provided information on the lowering of the central platform. Differential winch sensors were used to measure the opening angle of the shuttter doors when the platofrm was lowered.
Front, rear and profile views of a suction dredger showing the twin dragheads. Profiler can monitor any number of moving parts on the vessel. In this display, both dragheads are in the 'stowed' position.
