Precision Cold-Cutting & BROKK Debricking within the Complex Geometry of a Large Refractory Vessel

Aperture after Cold Cutting - Brokk 180 with Extended Boom deconstructing Lobster-back Refractory

Precision Cold-Cutting & Robotic Kiln Deconstruction

Robotic demolition specialists Gnat-UK were entrusted with a highly complex project: precision abrasive cold-cutting on a massive industrial vessel, followed by a full robotic debricking of its interior.

Owing to the vessel’s sheer scale and intricate geometry, traditional access methods were impossible. Our cold-cutting phase created safe entry points through the vessel’s side, enabling the dismantling works that followed.

Once the access route was established, a Brokk 180 with an extended, custom-designed boom was deployed to methodically remove refractory brickwork and castable linings. This unique setup allowed us to reach even the most demanding areas, including the angled Lobster Back Section.

With the Lobster Back cleared, scaffolding and a hoist provided access to the vertical shaft. In this confined space, our compact Brokk 70 robot took over, progressing chamber by chamber until the final breakthrough was achieved at the vessel’s base.

The result: another technically challenging project delivered safely, efficiently, and on schedule.
