The Brush Cleaning Tool (P/N: RQ-021) is an ROV operated motorised rotary brush designed to clean out 12 ½ inch subsea wellheads.
The rotary brush is driven by a hydraulic motor capable of reaching speeds of up to 400 rpm. The motor is also bi-directional can rotate clockwise and counter-clockwise. A case drain port on the hydraulic motor prevents over pressurisation of the hydraulic motor during operation.
The rotary brush head has tough, but flexible bristles positioned to provide maximum cleaning. An acid injection port allows acid to be directly pumped into the wellhead through
