Pipeline Maintenance & Repair for Marine Division

Navigable Waterway Surveying (DOT Compliant)

FEATURING OUR NEW MULTIBEAM SYSTEM!Pipeline

CSU utilizes systems that allow for XYZ pin point on the bottom of the waterway, useful when dealing with government dredging operations and exposed pipelines. CSU uses RTK systems combined with static data to give you true elevation and location to the earth’s surface. The RTK system along with side-scan sonar combined with our drafting department ensures you get the best report in a timely manner (same day in some cases!).

Our new Multibeam System is an optional addition to the navigable waterway surveying giving the operator a more detailed look at the bottom of the water way.
