Tank-Inspection Service

Intertek introduced a remotely operated vehicle (ROV) potable-water-tank inspection service that offers clients the option of using ROVs to inspect their large-capacity water tanks. Potable-water-tank inspection must be carried out periodically to mitigate health risks to those working on offshore platforms or in other facilities that require their use. Inspections should detect any 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 that can be hazardous and time consuming, sometimes taking up to 3 days. Intertek’s new service allows clients to send in a mini-ROV instead, 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 can make treatment recommendations, including operational advice, cleaning, patch recoating, or complete tank refurbishment. In addition to tank inspection and potable-water-­management services, Intertek Production and Integrity Assurance provides clients with a range of related solutions, including Legionella management, water-system disinfection, microbiological surveys, molecular analysis, media test kits, and oilfield-­microbiology training.
