Applications / User Benefits

Innomar's narrow beam parametric sub-bottom profilers are used worldwide for many tasks and applications during marine explorations and investigations:

• Geological and geophysical explorations
• Soil investigation campaigns for dredging projects
• Route surveys for pipeline and cable laying projects
• Detection of sediments for dredging tasks
• Search for mineral resources
• Surveys in small and (very) shallow waters, harbours, flood gates, shore zones
• Search for objects like wrecks, pipelines, sea cables, navigation obstacles, boulders
• Archaeological investigations for wrecks, historical buildings and settlements

Advantages of Parametric SBP / User Benefits

Using nonlinear acoustics for sub-bottom profiling gives the following advantages compared to linear sound generation:

• Narrow sound beams at low frequencies with small and portable transducers, the half-power beam width is nearly the same for all generated frequencies.
• There are no side lobes for the low-frequent sound beam during transmission.
• Very short sound pings without significant ringing effects can be transmitted.
• Detection of sediment layers and objects with high resolution plus accurate water depth determination due to high-frequent channel of primary frequencies.
• Good sediment penetration (depending on material, water depth, frequency and environmental conditions).
• Mobile systems with user-friendly control software for the employment on small ships, usable also in shallow waters and in complicated areas.
• Digitally stored data with excellent, reliable results with online data analysis and extended post processing capabilities.
• Saving of ship costs and expensive soil samples.
