Hydrographic Surveying Services

Hydrographic Surveying Services

Measuring and mapping navigable and non-navigable water bodies and accompanying shorelines and beaches is an essential part of our hydrographic surveying practice. We understand that life does not stop at the shoreline and our clients often need to know the location and condition of their assets in and around water bodies of all sizes.

Our hydrographic surveyors provide the surveying and mapping tools necessary to locate and map submerged obstructions, prepare for underwater construction, monitor coastline erosion, provide data for hurricane recovery programs, measure depths and compute volumes for dredging projects. Our hydrographic surveying services also routinely include pipeline route surveys, depth of cover surveys, and rehabilitative program support from our survey vessels.

Multibeam Sonar 

The advantages offered by our multibeam sonar are impressive. Like a single-beam device, multibeam sonar allows for fan-shaped coverage of the ocean floor, but with substantially more detail captured in the process. Multi-beam systems measure the time that each signal takes to travel from the device to the seafloor and return again. By measuring the time, the distance to the seafloor can be calculated, and by knowing the angle at which the signal was sent from the device, the depth can be calculated.

When you put that tremendous amount of data together, a three-dimensional representation of the seafloor can be created, giving a much greater degree of accuracy to the resulting data and imaging. Blind spots can be eliminated. Hazards can be identified and avoided.

With the right equipment and people, like Whiteley Oliver’s multibeam sonar hydrographic surveying, survey time is shortened, and you save valuable time and money.

As a result, efforts that depend on accurate seafloor imagery and surveying, such as locating a pipeline in need of repair or maintenance, can become substantially more efficient. Dredging operations can be planned for maximum efficacy and profitability.
