A Thickness G1auge for measuring metal thickness in locations previously inaccessible to divers, other ROVs and underwater inspection systems, AND a Laser Scaling head for the relative measurement of surface defects, anomalies or anything within its view. Thickness Gauge Thickness measurement is an established integrity monitoring technique in industry. Offshore or onshore, the AC-ROV can now deploy a thickness sensor in support of your maintenance, safety and survey requirements of anything metal and underwater. The vehicle mounted probe reduces inspection time and diver costs. There is no specialist training requirement and this means fast, accurate and repeatable results. Measurements can be taken through coatings as there is no need for special surface preparation, coating or corrosion removal. Measurements can also be electronically stored for report generation. • • • Greatly Reduce Inspection Time and Costs No special surface cleaning or preparation required Accepted by major Classification Societies Inline with the AC-ROV ethos of mobility, portability and robustness the solution is an integrated arrangement of the Cygnus multiple echo diver and ROV deployable thickness sensor. The outcome retains the clean, robust and snag free shape of the AC-ROV, whilst the top side hardware and interface is 100% Cygnus standard. The market leading mobility of the AC-ROV enables complete “ORBITAL” thickness measurement. A capability never before available by ROV without a manipulator. The first truly comprehensive small ROV thickness inspection capability. • • • Unrivalled Ingress and Inspection Capability Robust, Serviceable and fully Integrated Design Unique “ORBITAL” Inspection Capability Laser Scaling The AC-ROV Laser Scaling system is a fully integrated twin laser unit that projects two parallel laser beams onto any target giving an exact indication of scale. In a market first, the AC-ROV Laser Scaling system utilises variable intensity lasers so beam strength can be adjusted according to the conditions without compromising video quality. • • • Variable Intensity Simple ‘no modification’ Retrofit Recordable Results Another integrated and simple retro-fit AC-ROV capability solution combining proven technologies.
