ROSON seabed CPT system
With over four decades of offshore experience, the ROSON is a reliable seabed Cone Penetration Test (CPT) system that combines compact design, high performance and maximum operational flexibility. Designed for safe and efficient geotechnical investigations, ROSON systems are widely used in nearshore, offshore and ultraādeepāwater environments. ROSON seabed CPT systems are manufactured by A.P. van den Berg and are proven worldwide in demanding marine conditions.
Seabed CPT system since 1982
The ROSONā1D, ROSONā2D and ROSONā3D are compact and versatile seabed Cone Penetration Test (CPT) systems, designed for efficient and reliable geotechnical soil investigations without the need for drilling. Deployed directly on the seabed, the ROSON systems combine high pushing capacity with operational flexibility, making them suitable for a wide range of offshore projects. These systems have been successfully applied worldwide for nearshore, offshore and deepāwater CPT campaigns, delivering consistent, highāquality data even under challenging marine conditions.

ROSONāST ā For safe & fast seabed CPTs
The ROSONāST configuration is specifically developed to improve operational safety and efficiency during seabed CPT operations. By eliminating the need for a support CPT string, the system reduces handling risks and significantly accelerates installation and operation.Ā Thanks to its optimized deployment concept, ROSONāST can achieve a production increase of more than 30%, making it a highly efficient solution for timeācritical offshore projects.
Safe and efficient Why the ROSON-ST?
-
-
- Enhanced operational safety ā support CPT string eliminated
- Fast deployment ā >30% increase in production output
- Suitable for vessels of opportunity
- CPT penetration depth up to 50ā80 m
- Ć 40 mm CPT rods for straight and continuous penetration
- Designed for offshore and deepāwater applications
