Go Back > Sonar Measurement and Modeling
Several sonar plots are joined in CAD with blueprint dimensions to produce models of debris buildup or structure deterioration. The sonar references the structure, and absolute measurements or relative measurements can provide a wide range of answers for a structure.
The ROV placed the sonar to plot
the debris buildup against a lower
outlet intake structure.

The structure was approximated
in
CAD and a diver-held sonar
was used
to map
out failures
inside a submerged support
colum. The sonar plots showing
material
loss
in the column
are in black.
