Pipeline Surveys


(SUBMERGED, BURIED)

 

Subbottom

Pipe in Subbottom Record

Sea Surveyor has over 25-years experience at surveying submerged pipelines located on, or buried beneath, the seafloor.  We use Sophisticated geophysical sensors to determine a pipeline’s exact location and depth-of-burial, including side-scan sonar, subbottom profiler, marine magnetometer, and EM probes.  Divers inspect exposed pipelines, and use jet-probes to measure sediment depth over buried pipelines.
