Rendered Sonar Data


This image shows a bathymetric survey of a High Density Polyethylene Pipe river crossing. The sonar mainly shows the saddle weights and not the HDPE pipe itself.

RIVER CROSSING DELIVERABLES

AutoCAD Drawing
The image above shows the pipe elevation under a river. The depth of cover can also be seen.

Side Scan Sonar Image
This image shows disturbed rip-rap pipe protection.
Side scan sonar illustrates bottom conditions and can alert
engineers to possible hazards to the pipe.

Pipeline risks are compounded by the fact that a scour, degradation, and lateral
movement risk assessments are seldom performed at most crossings

Combine underwater sonar with above water laser for a more complete picture.

Sub-bottom Sonar Image


This image shows the gas pipe exposed and above the river bottom. Sub-bottom profiling gives depth of burial in most conditions.

Exposed pipelines are vulnerable to long-term issues such as abrasion and
corrosion and short-term issues such as direct attacks from hydraulic forces or
debris during high flows. These issues are critical to maintenance costs.
