Remotely operated vehicle for eliminating man-entry

Page last modified
Tuesday, March 30, 2021 - 15:57

Purposely built to fit through standard manways, Rover is a remotely operated vehicle that minimises and frequently eliminates exposure of personnel to hazardous environments. Rover’s sturdy tracked design and ability to operate in all conditions makes it ideal for unloading catalysts as well as cleaning and inspecting all types of confined spaces. Rover helps to reduce schedules, as it can start work earlier and doesn’t need frequent rest breaks, unlike its human equivalent.


Proven commercially since 2017
Recent experience with offshore and onshore end users including hydroprocessing reactors
Significantly minimises inert and confined space entry
Reduces catalyst replacement and cleaning schedules
Operates in all conditions including hazardous atmospheres and underwater
Zone 0 certification pending
Currently requires a 20 inch manway or larger
Requires customised attachments to break up heavily fused catalyst


Areas of Application Offshore and onshore | Catalyst unloading | Tank cleaning | Vessel inspection | Inert entry
ATEX certified Zone 0 certification pending.
Capabilities Rover is equipped with lights, camera and a vacuum hose. An additional mechanical arm can be customised for specific applications, such as removing fused or coked catalysts.
Non man entry Rover significantly minimises and frequently eliminates the need for technicians to enter confined spaces — substituting risks to personnel with innovative technology.
Operating conditions Rover operates under all conditions including hazardous environments, underwater and in temperatures up to 100 degrees Celsius.
Power 3-phase power pack.
Speed Rover reduces schedules as it can start jobs earlier and does not need to take frequent rest breaks, unlike its human equivalent. For large reactors, multiple units can be used simultaneously to minimise schedules further.
Temperature Withstands temperatures up to 100 degrees Celsius.
