Datem Neptune
5000 CPT
The Datem Neptune 5000 is a robust and compact coiled rod Cone Penetration Testing (CPT) system designed for subsea soil analysis. It delivers highly accurate, real-time data on key soil parameters, which reduces the need for time-consuming soil sample extraction. This streamlined process ultimately shortens project timelines and lowers operational costs.
Global CPT Site Investigations: Leading with the Datem Neptune 5000
CMS GeoScience stands as a leading marine geotechnical survey company, providing CPT site investigation services across the globe. We own and operate our Datem Neptune 5000 CPT system, ensuring accurate, reliable and cost-effective solutions for a wide range of seabed investigation projects.
Precision Data & Innovative Design
The Neptune 5000 CPT system utilises 5cm² or 10cm² digital Piezocones, offering comprehensive testing including T-bar, ball cone, and dissipation tests. This allows for penetration depths of up to 20m below the seabed (dependent on ground conditions). With real-time data capture and control from the topside vessel, the system delivers highly accurate evaluations of subsoil stratigraphy and the geotechnical and geo-environmental properties of the seabed.
Its innovative, compact, and modular design, comprising rods and a drum, makes the Neptune 5000 CPT easy to deploy from smaller, more cost-effective vessels.
MV Flatholm: Unrivalled Efficiency in a Compact Class
Complementing our CPT capabilities is our own 24m survey vessel, MV FlatHolm. Unique in its class for its manoeuvrability and exceptional lifting capacity, MV FlatHolm consistently outperforms larger survey vessels in terms of efficiency, speed, and cost, all while maintaining an unwavering commitment to safety.
