Near- & Offshore CPT systems

We build the future together

We deliver robust, modular CPT solutions for shallow to ultra-deep water, including the ROSON and WISON-APB systems. Through in-house engineering, continuous innovation, and dedicated support—from installation to after-sales—we provide customized offshore CPT systems that perform reliably under all conditions.

ROSON – compact, powerful, and proven

Since 1982, the ROSON seabed system has been the global standard for offshore CPT. With an extensive track record, it is suitable for water depths of up to 4,000 meters and available in multiple configurations.

The latest generation, the ROSON-ST, is a compact and safer evolution. By integrating our patented ST technology, the system operates without a CPT string, improving safety, accelerating deployment, and increasing productivity by up to 30%. The ROSON-ST is designed for offshore applications up to 4,000 meters water depth and CPT testing up to 80 meters below seabed.

WISON-APB – heavy-duty CPT performance

The WISON-APB is a wireline CPT system developed for geotechnical vessels equipped with a drilling tower. Designed for ultra-deep water operations up to 3,000 meters, it performs reliably in harsh offshore environments. With a fully electric drive, real-time data transmission and excellent performance in complex soil conditions, the WISON-APB delivers high accuracy and efficiency for demanding projects.

Quality from start to finish

Our strength lies in in-house engineering, continuous innovation, and comprehensive support—from installation to after-sales—allowing us to deliver tailored offshore CPT solutions worldwide.
