Through all phases of waterfront and underwater projects, hydrographic surveys provide critical information about the depth and character of the bottom. SeaVision provides hydrographic surveys around the world to clients in all phases of projects, often working in difficult-to-reach areas. Techniques we employ include:
• Real-Time Kinematic GPS Positioning
• Single Beam Echosounding
• Multibeam Echosounding
• Dual or Multi-Frequency Echosounding
RTK-GPS Positioning provides us with highly accurate horizontal and vertical positioning that also compensates, in real-time, for changing water level conditions. Single Beam Echosounding can be an effective tool for very precise depth measurements, especially in shallow environments.
Multibeam Echosounding generates very accurate, very dense data sets that provide nearly 100% coverage of the bottom and result in highly detailed bathymetric maps. And finally, Dual or Multi-Frequency Echosounding can be deployed to measure thicknesses of sediment layers or searc for buried utilities or objects.
In our Projects section, you will see sample projects that illustrate diverse applications of the hydrographic survey techniques that we employ. We find ourselves working through all phases of projects, including Design/Permitting, Construction, and Operations & Maintenance. Led by an ACSM-Certified Hydrographer, SeaVision provides these survey techniques in accordance with USACE and IHO Standards. Whether at a major container ship terminal or at a pumped-storage hydroelectric facility, SeaVision has the experience and the capability to deliver.
