Seismic reflection surveying is a technique that generates high-resolution images of the seabed profile by triggering and receiving seismic wave signals. This method can precisely locate the burial positions of seabed installations (such as pipelines, cables, and mattresses) and detail the morphology and depth of seabed trenches. Such information is crucial for ensuring the accuracy of facility installation and geological safety, providing essential geological data for subsequent construction and maintenance activities.

Innomar SES-2000 Standard Parametric SBP System

The Innomar SES-2000 is a high-precision sub-bottom profiler that utilizes Secondary Low Frequency technology, widely used for underwater geological surveys. This equipment offers multiple center frequency options, allowing for flexible selection between 4 and 15 kHz based on the survey environment to adapt to various underwater geological conditions.

Key features include:

• High Resolution: The Innomar SES-2000 provides a sampling resolution below 1 cm, with a range resolution reaching up to 5 cm. This ensures precise imaging of shallow sediments and subtle geological structures, offering clear data support for geological research.

• Penetration Depth: The signal can penetrate sediment layers up to 50 meters deep, with the exact depth depending on sediment type and environmental noise conditions. This deep penetration capability is suitable for areas with thick sediments, such as seabed trenches and sediment studies.

The Innomar SES-2000, with its high resolution and deep penetration capabilities, is an ideal tool for marine geological surveys and underwater archaeology. It meets the diverse detection needs for both shallow and deeper structural exploration.

Towed shallow seismic reflection surveying

The AA251 Boomer Plate and 20-element hydrophone array are high-resolution shallow seismic reflection devices designed for high-frequency shallow reflection surveys, suitable for marine and shallow water environments, providing clear images of shallow strata. The AA251 Boomer Plate serves as a high-frequency short-pulse source, ideal for studying shallow sediments from 10 meters up to several tens of meters. The 20-element hydrophone array, as the receiving device, enhances the signal-to-noise ratio through an array design, making it well-suited for detailed sediment, stratigraphic surveys, and underwater archaeology.
