This case study examines the depth of burial survey of natural gas pipelines crossing the Columbia River near Portland, Oregon, using an Innomar medium-100 parametric sub-bottom profiler.
- This study demonstrates the capabilities of an Innomar parametric sub-bottom profiler system to detect buried pipelines in a river environment and determine their depth of burial
- A section of the Columbia River was surveyed with a few parallel lines (direction along the river) at water depths of 5 to 15 meters
- Additionally, the area was surveyed with a NORBIT WINGHEAD®i80S Long Range multi-beam system for high-resolution bathymetry.
Equipment used: - Innomar medium-100 parametric sub-bottom profiler
- NORBIT WINGHEAD®i80S Long Range featuring integrated Applanix Oceanmaster INS/GNSS and AML SV sensor
- NORBIT PORTUS pole mounted over the side on an 8m survey vessel
- AML-3 sound velocity profiler
