HOUSTON – At the Offshore Technology Conference, Intertek launched a potable water tank inspection service that offers the option of using ROVs to inspect large-capacity water tanks.
Potable water tank inspection must be carried out periodically to mitigate health risks to those working on offshore platforms or other facilities. They can be used to detect evidence of contamination, biofilm deposits, corrosion formation, and the growth of Legionella.
Typically, potable water tanks are taken out of service to be emptied and inspected directly by personnel, a process which Intertek said can be hazardous and time consuming, sometimes taking up to three days.
The new service is designed to allow clients to instead send in a mini-ROV, which removes the need to drain and refill the tank, mitigates risks to personnel, and can ensure that tanks are back in service after 12 hours.
When evidence of corrosion or bacteria is detected, Intertek said it can make treatment recommendations, including operational advice, cleaning, patch recoating, or complete tank refurbishment.
Intertek is exhibiting at booth #3977.
