Datem Neptune 5000 CPT

Datem Neptune 5000 CPT

[Category: Ocean/ Marine Services-Construction (marine/port/harbor)]

The system utilises 5cm2 or 10cm2 digital Piezocones, including T-bar, ball cone and dissipation tests to penetration depths of up to 20m* below the seabed (depending on ground conditions) With real-time data capture and control from the topside vessel the system allows highly accurate evaluation of the subsoil stratigraphy and geotechnical & geo-environmental properties of the seabed. The Neptune 5000 CPT benefits from an innovative design comprising rods & drum creating a compact and modular system that can be easily deployed from smaller and more cost effective vessels.

High Powered Vibrocorer

[Category: Ocean/ Marine Services-Construction (marine/port/harbor)]

Our systems have proven to achieve possibly the best penetration and recovery statistics of any high-powered vibrocorer operating in the UK in the last few years. With over 20 years of operational experience we have adapted and re-designed the vibrocore barrels to build on reliability and strength as well as improve speed of deployment turnaround. All of our systems have their own real-time topside display ensuring accurate deployment and operation of the system, which when coupled with the operational knowledge of our geotechnical team, delivers an unrivalled package of high quality, accurate and cost effective results every time. We firmly believe in minimising sample disturbance and the realtime surface display of penetration allows the experienced operator to cease the test when all useful progression has been completed.
