Muddy Water Dredging’s new cutter suction dredge With Vaneta Marie, the DSC team was able to match (CSD) Vaneta Marie “represents the future of dredging “unparalleled performance with forward-thinking designs”, technology”, according to Bill Wetta, senior vice president, Wetta said. Notably, the dredge features DSC’s survey-grade and chief technology of? cer of DSC Dredge, the Reserve, DSC VISION package and Dredge Rx remote monitoring

Christened during a ceremony in New Orleans earlier “DSC Vision is a multi-beam sonar that’s attached to the this year, Vaneta Marie is a fully customized Marlin Class dredge, and sonars typically don’t really work unless there’s dredge that measures 371 feet long, making it one of the movement. . . We use the motion of the dredge to create longest in its category. the motion for the sonar. So we’re actually looking at a line

Boasting the capability to dredge a 400-foot-wide cut perpendicular to the center of the dredge, maybe 100 feet with an 80-degree swing arc, it sets a new standard for forward of where the cutter head is, and all the way back operational ef? ciency, enhancing productivity by 5.9%. behind where the ladder pivots at the trunnion.
