SINGLE / MULTI-BORE HUB CLEANING TOOLS

Fugro-impROV’s Hub Cleaning Tools allow the cleaning
of sealing faces of various wellhead connectors using
a rotary cleaning assembly comprising of commercial
grade cleaning pads being driven by a hydraulic motor.
Standard versions are available for 13-5/8” and 18-3/4”
wellheads; however any hubs (size/ no. of bores) can
be catered for.
The motor is hydraulically supplied from the on-board ISO13628-8 Type A Multi-bore cleaning clusters
dual port hot-stab receptacle which incorporates dual low crack pressure
check valves. This allows bidirectional cleaning, while minimising water
ingress when not in operation. A set of in-line flow regulators are factory
set to allow a predetermined cleaning head RPM. The Tool features 3
off landing feet which help centralise it on the hub and sets the cleaning
pads at a pre- determined distance from the intended sealing faces to be
cleaned. This stops the ROV from being able to exert any unwanted force
on to the hub during operation and offers a much more uniform cleaning
result.
The cleaning is done by replaceable pads of ‘Scotchbrite’ type material
(available in varying grades) which conform to the sealing face and clean
without scoring. Integrated acid injection local to the pads can also be
incorporated. Cleaning Tool on hub
