Seatools Presents Carrera E Precision Flow Excavation Spread

Following an extensive R&D trajectory, Seatools is now introducing the Carrera E 3D motion-controlled precision flow excavation spread. 

“Seatools developed the Carrera E mass flow excavation spread leveraging its proven capabilities in heave compensation and ROV control technologies. The patent-pending spread features 3D motion control, which enables precision excavation operations at a minimum of seabed disturbance,” the Dutch subsea technology company stated.

“Thanks to the Carrera E’s incorporated dynamic positioning (DP) capabilities, the tool may follow a pre-programmed track (e.g., a cable route) with high precision and in a highly automated manner.”

Johan Sol, responsible for business development, said: “Early on in the development process we analyzed excavation operations as well as the direct and indirect cost drivers from a client point of view. Especially in terms of indirect cost drivers – vessel day rates, environmental downtime, survey costs, and crew costs – we found significant room for improvement: in some cases, total project costs could be cut by 50% while realizing reduced environmental impact and safety improvements.”

With over 500 kW of installed power dedicated to dredging, the spread takes on a wide range of soil conditions.

The LARS, including tool, only requires a 20-foot container footprint and a minimum of vessel interfaces. Combined with the fact that no tugger wires are required, all this means the Carrera E can be deployed from a wide range of vessels, including smaller, low day rate vessels.
