Scanning device to assess caisson conditions offshore Qatar
Offshore staff
ABERDEEN, UK– North Oil Co. (NOC) has contracted AISUS to perform two caisson inspection programs on facilities at the Al Shaheen oil field offshore northeast Qatar.
Al Shaheen, 80 km (50 mi) north of Doha in the Persian Gulf, produces around 100 MMbbl/yr through 33 platforms.
AISUS will use its ultrasonic scanning tool, SIRIUS-X for the campaign. This is a tethered system which, when deployed from the topsides, allows inspection data to be captured above, within and below numerous obstacles and diameter variations that are commonly encountered within caissons, without the need to remove the tool.
The system, which according to the company minimizes the duration of inspections, features a high torque rotary drive with a scanning speed of up to 5 m/hr (16.4 ft/hr).
