More than 200 patents sit behind the platform, which combines high-pressure systems, vacuum extraction and intelligent remote operation under full control from the surface.

  • Improved safety and faster vessel turnaround.
  • Safer and faster robotic cleaning, without chemicals.

Robotics & Industrial Solutions

Robotics Division

Entrance Robotics builds AI-powered, explosion-proof robots that strip sludge, mud and contaminants out of tanks and confined spaces. Cleaning cycles close faster, assets go back into service sooner, and operators stay outside the vessel.

THE PROBLEM

The Hidden Risks of Manual Tank Cleaning

Manual sludge removal in confined spaces exposes workers to extreme hazards, including toxic gases, heat stress, and physical injury. Cleaning cycles are slow, inefficient, and highly dependent on human performance, leading to downtime and increased operational costs.

More info

Industrial Tank Cleaning Robots

Do your robots require confined-space entry permits?

No. The robots are deployed through existing manways and operated remotely from outside the vessel, which removes the need for personnel to enter the confined space during cleaning.

Are the robots certified for explosive atmospheres?

Yes. The equipment is certified for ATEX Zone 0 and Zone 2 environments and carries CE marking, so it can operate inside hydrocarbon storage tanks.

How much sludge can be removed per hour?

The Wallhiker HD-01 handles between 5 and 30 cubic metres per hour depending on sludge density, with a maximum vacuum of 0.09 MPa.

Are chemicals used during the cleaning process?

No. Cleaning relies on high-pressure water, mechanical agitation and vacuum extraction, which avoids chemical handling, disposal costs and the associated environmental permits.
