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.

Marine Pipeline & Facility Construction

CSU has specially designed barges, dry welding caissons, and boats made for dynamic conditions to lift, lower, repair or transport pipeline in hard to reach areas. Pipeline stabilization

Bank Stabilization

Pipeline Bank StablizationCSU utilizes historical data charts and flow readings to identify and map the waterway over time. With this data in conjunction with our knowledgeable staff and advanced technology, CSU has the ability to stop erosion and even move the waterway back to its original course. With over 35 year of experience throughout the United States, CSU has completed bank stabilizations that range in size from small creeks to the Mississippi river. Let us show you how to fix it the right way the first time!
