CRD100 Seafloor Drill

Quick Information

Description:

The CRD100 is a state-of-the-art, self-contained, remotely-operated drill that can case, core, and Cone Penetrating Test (CPT) to between 65-120 meters below the seabed depending on the sampling configuration and soil characteristics. The CRD100 can operate in water depths down to 3000 meters. 

Tool handling is performed automatically, improving drilling efficiency, and accurately tracking all tools and cores as they are recovered.

The drill includes maneuvering thrusters, navigation sensors and a suite of cameras which allow the surface operator to accurately position the drill, even in highly challenging terrain.

Design Highlights

Suite of Drilling Tools

Cellula drills are designed to handle changing conditions during a drilling campaign. If an unexpected hard feature is discovered during a geotechnical CPT profile, the drill can switch tools, core through the feature and continue the CPT profile.

Relays Information With Precise Measurements

With the CRD100 deployed directly onto the seabed, precise downhole depth measurements can be made with respect to the mudline. Coupled with a precision digi-quartz depth sensor, CPT data can be accurately tied to existing data sets.  All measurement data is, in real time, transmitted to a dedicated Cellula-provided control van.

Outrigger Legs for Soft Ground depLoyment

The CRD100 can be fitted with four outrigger legs to prevent sinking in soft soil conditions. The legs keep the drill above the seafloor around the sample site, preventing ground compression where sampling is taking place.

With the outrigger fitted, the drill can be deployed onto soft ground and on slopes up to 15 degrees.

Cellula's patented foot design allows for passive suction release, ensuring the drill can be recovered even during a system failure.

Benefits

Improved Sample Quantity

Decoupling the vessel motion provides a stable drill platform on the seafloor.

Precise Seafloor Positioning

Four thrusters, navigation control and leveling legs provide accurate positioning on the seafloor, even on challenging terrain.

Universal Deployment

The CRD100 can be deployed from virtually any suitable DP vessel, allowing for flexibility.

Increased Safety

All tool handling is carried out remotely with no human intervention, eliminating the risk of danger and injuries.
