The world most powerful seabed excavator


The Seabed Excavator is the most powerful, multipurpose subsea tool carrier and dredging vehicle of its kind and capable of working down to 4000 meters water depth.

Seabed Excavator – Raising the bar

With its proven technology the Seabed Excavator sets a new standard for underwater efficiency and safety for subsea excavating operations.

A true multipurpose platform

The main roles of the Seabed Excavator are: excavating & dredging, decommissioning, drill cutt and rock dump removal, cutting and grinding,  scour protections and handling of cargo from ship wrecks. 

Minimal environmental footprint

The excavator is an electric multitool platform with a technology that ensures no oil spill or fluid leakage.

Compact rubber belts leaves a minimal environmental footprint.  

Proven technology

The Seabed Excavator uses hardware and software from a Perry Slingsby XLX ROV, combined with Kaiser Excavator body, to make a robust and versatile subsea system.

The dredging system, is amongst the most reliable and is manufactured with minimal parts to increase operational dependability.

This subsea excavator is capable of removing up to 230 – 400 ton  of seabed sediments per hour through the ejectors.
